Which side is up?

The Fel-Pro Break Room Forum has had several postings recently regarding which direction a gasket should face when installed. Some gaskets are asymmetric and the correct orientation can be visually distinguished. Sometimes gaskets for the same engine might appear very similar, but will not function properly if installed in the wrong direction. It is important to install these gaskets in the correct orientation.

 

Then you will find other gaskets can be installed with either side facing up and the gasket will seal either way.

 

So how do you know which way a Fel-Pro gasket is supposed to face when it’s being installed? Fortunately, in the case of head gaskets and intake manifold gaskets, Fel-Pro gaskets have directional markings to help install them correctly when the gasket’s orientation is critical to the repair.

 

Before we take a look at the different markings you’ll find on Fel-Pro gaskets, let’s talk about what we mean when we say front, left, right, top, and up. Front, left, right, top and up – why so many? Different nameplates use different nomenclature in their OE service manuals for directional markings. For consistency in leveraging repair information, Fel-Pro works to follow the nameplate reference.

 

Front:
What is the front of the engine? This can be confusing, especially when dealing with a transversely mounted engine (which most front-wheel-drive vehicles have). The answer is quite simple though – the front of the engine is the end where the drive belts are located.

 

front

 

Left and Right:
Left and right are determined from the driver’s perspective. That’s the industry standard. If you were to install your gaskets on the left and right side based on looking at the engine from the front of the vehicle, the gaskets would be incorrectly installed.

 

left_right

 

Top / This Side Up:
“Top” or “This Side Up” means that’s the side of the gasket that should be facing you once it’s installed.

 

top_this side up

 

Up:
This stamp is found on Fel-Pro head gaskets for Subaru engines (which have horizontally opposed cylinders). The edge of the gasket with the “Up” stamp must be kept up toward the top of the engine block.

 

Up

 

Non-Directional Gaskets:
In some cases, head gaskets or intake gaskets won’t have any directional indicators on them. They may have Blue Stripe® coating, or be a different color. In these cases, it does not matter which direction the gasket is installed. If it were crucial it would be marked.

 

doesnt matter

 

For example, the Small Block Chevy and the GM 3.4L V6 head gaskets (pictured above) can be installed with the Blue Stripe coating facing the cylinder heads or the engine block. There are no directional markings on the gaskets.

 

Water Outlet and Thermostat Gaskets:
Water outlet/thermostat gaskets can be installed with the striping facing either direction as well, again as long as there no directional indicators. If there are bypass holes (as seen in the image below), the gasket must be installed in the correct orientation to allow coolant flow.

 

water outlet

 

Exhaust Manifold Gaskets:
Exhaust manifold gaskets are another gasket type we get questions on. When installing Fel-Pro exhaust manifold gaskets, if there is a smooth, metallic side and a composite side, the metallic side should be installed facing out, meaning toward the exhaust manifold. This smooth surface of the shiny side will allow the flange of the exhaust manifold to slide as it expands and contracts during heat cycling from engine operation.

We hope this help address your questions on which way is up. Remember, if a Fel-Pro head gasket or intake manifold gasket does not have directional markings on it, it doesn’t matter which way it faces (even if there are stripes on one side but not the other). If you are unsure of the correct way to install a gasket on a particular application, leave a comment below or post a question in the Break Room Forum (registration not required to post).

    Hello
    I have a 05 trailblazer 4.2 and bought a gasket set , everything is going well but the exhaust gasket I do not know what to do . Only markings are felpro and some numbers (96302) both on one side . Do they face the block or exhaust

      Hi Patrick,

      Any time a gasket can be installed in more than one direction and still match up with the castings but needs to a face a certain way, we’ll mark it to show which way it needs to face. This gasket can be installed either way and you’ll get the same seal! If one side is smoother than the other (this may not be the case) you can place the gasket so the smoother side is facing the exhaust manifold. Otherwise install the gasket clean and dry with no RTV or other sealants.

        Thank you for your reply ,
        I was wondering if the beveled edge of the inside of the gasket holes needs to face exhaust or the head . In the past I had changed a thermostat and did not pay attention to the gasket . When i put it back together I cracked the housing because the beveled edge was upside down , i didn’t know if this applied here . I was not there when it was taking a part and I was told to use copper spray that I put on last night . should I remove it or will it be fine and the beveled edge face the exhaust or the head ?

          Patrick,

          That’s understandable! Rest assured this gasket can face either direction.

          We do not recommend applying any sort of spray sealants or adhesives to our gaskets. If you already have it installed you can leave it. The exhaust manifold gasket still requires proper installation, but this particular gasket doesn’t have any sort of coating the copper spray could interfere with. In the future, we recommend not using any sort of sealant or coating on our gaskets unless the factory repair manual calls for it.

    Hi Team,
    I’ve installed Fel-Pro 8548PT2 gaskets on my ’69 Ford 302 Windsor and due to overheating issues I want to double check if I have the gaskets installed the right way.
    If I stand in front of the car, looking from above I can see the number 8548PT2 on the front corner, exhaust side of the right bank. (thus, the number is on the head side at the front of the engine)
    If I look from underneath the engine, looking up I can see the number 8548PT2 on the front corner, exhaust side of the left bank. (thus, the number is on the block side at the front of the engine)
    Could you please assist?

      Hi Johan,

      As long as these gaskets were lined up properly with the engine block and cylinder head castings and the alignment dowels, they are installed correctly. The direction the Blue Stripe coating faces doesn’t affect sealing, it’s just our trademark. The same is true with the stamping for the part number.

    Hello & happpy Easter ! I am replacing my gaskets on a sbc 355 with edelbrock performer aluminum heads, i believe that my heads are fine but going to have them checked anyways which brings up my questions: .A. If I don’ t need them “decked” what gasket is best .B. If I’d. Have to have them cut, I would probably want to use a thicker gasket since I have a supercharger & want to avoid bumping up my compression ratio . Motor has about 5K on it since build , & heads were new right out of the box. Thanking you in advance, Jeff

      Hi Jeff,

      We need to ask you a few questions before we can recommend which head gasket to use.

      The Edelbrock heads should be smooth enough to use a MLS head gasket – was the block deck surface refinished? If so, was it finished smooth enough for MLS head gaskets? 60 RA or less is desired.

      Are these the 64cc or 70cc chamber heads?

      If the block was not resurfaced and still has the O.E. original surface finish you’ll need a composite head gasket. Our 1003 head gasket would work for this.

      If the block deck surface is smooth enough for a MLS head gasket, our 1142 gasket would be a good choice.

      Hi Roberto,

      Either side can face the engine. One side of the gasket may have a rounded edge while the other is flat, this is because of how the gaskets are stamped out during the manufacturing process and will not affect sealing.

    Hi. I purchased the ms 96789 gasket for a 2005 grand prix with 3800 series 3 with supercharger. I have seen 2 different versions of this gasket. The one I have has the blue sealant bead but the other has a different bead and metal grommets like the factory gasket had plus the yellow o rings. Mine does not have the grommets but does have the yellow o rings and a water gasket that I don’t know where it goes either. Do I need the grommets or do the o rings replace them?
    Thank you .

      Hi Robert,

      This design has changed over time. This latest design uses the 2 yellow O-rings fitted into the lower intake manifold grooves. The intake gasket, #96789, lays flat on the lower intake with the yellow O-rings in the center of the 2 coolant passages.

      I believe the “water gasket” you are referring to is actually a gasket for the PCV valve. There is a metal plate on top of the upper intake plenum and this is the gasket that seals the plate to the plenum. The black O-ring in the bag with the yellow O-rings is to seal the PCV valve in the upper plenum.

    Recently purchased MS 95702 exhaust manifold set for a 98 Ford Escort ZX2. Single item (gasket) in the box (as indicated by list of contents printed thereon), as opposed to a “set”. When I removed the exhaust manifold, there appeared to be 2 gaskets (or a gasket and a backing plate on the cylinder head side). Are these likely just the separated layers of a single old gasket ? Thanks for any clarification you can provide.

      Hi Grant,

      It sounds like the gaskets may have been doubled up (you don’t want to do this, doubling up gaskets to compensate for a warped flange will result in a leak), or that the gasket has separated. In either case, you’ll be good to go with the MS 95702 exhaust manifold gasket. Install it clean and dry and torque the exhaust manifold to the OE specification in 3 even steps.

    I have a 96 camaro rs 3.8. I just replaced the head gaskets with fel-pro I made the mistake of looking at the engine and thinking left and right was correct. Now I see it was wrong and it should’ve been from the driver seat left and right. I torqued them last night and used a little rtf to keep them in place… however everything lined up just fine.. other than the true left side… in front of driver seat having the blue striped face down. What should I do? Take off and put them in the order posted or will I be ok? Reuse the gaskets?

      Hi Tyler,

      It does not matter which direction the Blue Stripes face, they are applied as our trademark and for identification. However, the gaskets are manufactured as left and right because they must be installed on the correct cylinder bank. Also – RTV, adhesives or other sealants should not be applied anywhere on the gaskets, the block or the heads. There are alignment dowels which the gaskets fit over that hold them in place and keep them properly located during installation.

      The gaskets should be removed and discarded. The coating we apply conforms to the micro-imperfections in the sealing surfaces when the heads are torqued down, and reusing them can create leak paths. The gaskets only compress once, so you will not get a reliable seal if you try to reuse them. RTV and other sealants can interfere with the effectiveness of the coating we apply, so do not apply anything next time.

      It would be in your best interest to start with fresh gaskets and install them clean and dry on their respective cylinder banks.

      Hi Eric,

      The head gaskets in that set are not symmetrical, so if they are lined up with the castings and on the dowels, they can only be installed one way. As long as they fit on the dowels and everything lined up properly, you are in good shape.

      Hi Aldo,

      Your English is very good considering it’s not your first language!

      You are correct, the blue fiber side of the gasket should face the cylinder head, and the metal side should face the block.

      On the metal side only, you should apply an even coat of spray sealant such as copper spray or spray-tack. No sealant is needed on the fiber side.

      EDIT: We pulled this gasket from stock to take a look at it – the metal side has a gray moly coating on it – no sealer is required. If you already used sealer, it should be fine but it is not required. Do not apply sealer if you haven’t already.

      Good luck with your project!

    The gaskets that i have are MLS and both head gaskets are identical and are not marked Right or Left.
    Does the head gaskets with the small hole face or orientated towards the front?
    With the larger coolant holes towards the back of the motor?
    Is the left the drivers side and right is passenger also?.

      Hi Leo,

      What part number gaskets or gasket set did you purchase, and were the gaskets new in their original packaging when you received them? The gaskets should be marked left and right, and also top/front on one end – they are specific to the side they belong on and the position they should be installed in. The markings would be on the “ears” of the gaskets.

      The left side requires part # 9250 PT, or 26505 PT if you opted for the version which is .010″ thicker which is used to compensate for material removed if the heads and/or block was machined.

      The right side requires part # 9253 PT, or 26506 PT if you opted for the version which is .010″ thicker which is used to compensate for material removed if the heads and/or block was machined.

      It is the automotive industry standard to identify the left and right side of a vehicle (and therefore the cylinder banks of the engine) from the driver’s perspective, sitting in the vehicle, facing the front of the vehicle.

    I have ordered the FEL-PRO MS98011T1 intake manifold gasket set for my 2001 Ford Windstar. The Haynes Repair Manual says to “install the rubber in seals to the block using a thin layer of RTV sealant” and also shows a picture of the end seals with the caption, “Install the rubber end seals over a this bead of RTV sealant then apply a thin bead on top”.

    Is this accurate?

          Hi David,

          The gaskets are designed to help control the flow of coolant through the intake manifold. The passages in the gasket need to be a certain size to keep going flowing properly and at the right speed in order to regulate the temperature. Install the gaskets as they are.

          This is one of the few instances where it would be ok to reuse a gasket. Because you used the PermaDryPlus intake gaskets and did not run the engine, the molded rubber sealing beads will not have taken a compression set yet. It will be ok to reuse the intake gaskets, just be sure you clean the RTV up from the 4 locations it should have been applied to – where the ends seals meet the intake gaskets. You will need to apply RTV in these 4 areas again when you reassemble the engine.

          Do you know what caused the right side head gasket to fail? Unless there’s some specific reason the right side failed, the left side will have been exposed to similar conditions and may not be far behind. We strongly recommend replacing both gaskets while you’re there. If you end up needing to replace the left side later, you will not be able to reuse the intake gaskets as the heat and thermal cycling caused by running the engine will result in compression set of the molded rubber on the intake gaskets.

I got the car pulled over and had to have it towed home. I am still hoping it is the head gasket and not something worse. The engine got very hot, as evidenced by the paint on the valve cover was blistered.

            David,

            Did you inspect the cylinder heads and block for flatness, or have them inspected by a reputable machine shop? It sounds like you’re dealing with warped castings as a result of the overheat. Replacing the gaskets will not help if that is the case, as the castings will need to be repaired or replaced.

    FEL-PRO,
    Good morning and I do wish I had come across your excellent info yesterday. What do you suggest for the following mistake. 1984 Dodge Ram W150 with a 318. I started to replace the Exhaust Manifold gaskets yesterday before the base shop closed and I will get back to it on Wednesday. I disassembled both sides and cleaned the engine block smooth and clean. I cleaned the exhaust manifolds similarly but did have pitting but are otherwise clean and smooth. The pitting I would say was minimal but present. I started reassembling and got the right side / passenger side back together. I used the appropriate FEL-PRO gasket, BUT I followed a shade tree mechanic’s advice and coated both sides with high temp exhaust manifold orange RTV. As if that wasn’t enough, I installed the shinny metallic side toward the engine block. Again both sides have the RVT. My plan was to do the same on Wednesday when I can get back to the auto hobby shop and complete the job. Do I disassemble the right side and purchase a new set of gaskets and clean both surfaces again and install shinny side out and no RTV? Or 2) install the left side incorrectly just as I did the right side? or 3) install the left side per FEL-PRO instructions (shinny side out to a clean and dry surface) and see which side fails first? The truck is an occasional use truck, maybe 2,500 miles a year. Thanks. Mike

      Hi Mike,

      At the very least, install the other gasket clean and dry with the shiny side facing the exhaust manifold. We recommend replacing the gasket that was covered with RTV and cleaning the surfaces again, however, most of the RTV will burn up with use so it’s not the end of the world. Exhaust manifold gaskets won’t split or extrude due to RTV like molded rubber or composite gaskets. Our concern is with how the RTV/flipped gasket combo will handle the expansion and contraction of the exhaust manifold. You may see premature failure on that side since the manifold will “scrub” away at the RTV and gasket as it expands and contracts.

      Hi Steve,

      There are many gaskets and seals in the HS 9071 PT-3 set, so we aren’t sure which ones to give you specific advice on. However, none of the gaskets in that set require sealer to be applied directly to them. RTV is used to form the intake end seals and will contact the intake manifold gaskets in the 4 areas where the “legs” of the intake gaskets reach toward the end seal area. however, no selant is to be applied around the ports on the sealing surfaces of the gaskets.

    WHY? :/
    The 6.2/6.5 are already prone for overheating, so shouldn’t a full size hole help to cool better??
    Want to hear Your explanation before I drill up these holes in my gaskets 🙂

    Reply
    1. Fel-Pro Blog TeamFel-Pro Blog Team

      Hi Glenn,

      Do not modify the gaskets in any way. The holes in the head gaskets are precisely sized to meter the flow of coolant through the heads. An improperly sized or placed hole can create a “shortcut” which prevents coolant from following the correct “path” through the engine. If the coolant takes a “short-cut” because a coolant hole is too large at the front of the engine, the rear cylinders can overheat. If the holes are properly placed, but too large, the coolant can pass through the engine too quickly and fail to absorb enough heat, also resulting in overheating.

      Engine blocks and heads are sand-cast, meaning sand forms the mold for the casting. The holes must be large enough, and sometimes extra holes must be added, to allow the sand to be completely cleaned from the casting once it has solidified, which is why the holes in the heads and block are so much larger than the holes in the gaskets.

      You can install them with either side facing up, the embossments only stick up on one side but create sealing stress on both sides of the gasket. The 1094 gaskets have a clear coating on them, and no additional sealer or adhesives should be applied.

      This thermostat seal will go on either way. In the case where some of these types of thermostat seals may have a slight taper on the outside edge, it may be easier to place the taper down for the installation. No lubrication or sealer is required – install clean & dry.

    1. Fel-Pro Blog TeamFel-Pro Blog Team

      Hi Andrew,

      The rounded edge is just from the stamping process during manufacturing. Install these gaskets so that the smooth/shiny metal side faces the exhaust manifold – this allows the manifold to “slide” as it expands and contracts from heat cycling. If both sides of the gasket are smooth/shiny, it doesn’t matter which side faces out.

    Greetings, last year I put together a sbc stroker motor. I used Felpro 1010 gaskets and there were instructions on drilling a head gasket matching, cooling hole in the lower center of the chevy block, between clys 3-5 on left and 2-4 on right. The idea was to open up these cooling holes by drilling a hole that matches the block and heads. Ideas was to open up a hot spot in the block. In doing so, my temps are now slightly lower than before.

    When I discuss this with other guys, they say they have never heard of this. Can you elaborate on this and provide links to this on the 1010 head gasket?

      We know there are engine applications where it is recommended to drill heads or blocks to assist in cooling, but not the other way around. The head gasket has holes of certain sizes in certain places to meter and control coolant flow through the engine. Modifying this coolant flow could result in cooler temps as if did for you or could result in overheating as the coolant isn’t flowing through the engine as it should.

      Where where the directions coming from that suggested modifying the head gaskets?

    I have a 68 Camaro with a 396/325. The exhaust manifold is very visible when looking at the engine. Why is this gasket in one piece rather than 4 separate pieces per cylinder head. The portion of gasket between the cylinders only collects dirt, grease, and oil and does not appear to serve any practical purpose. Can this gasket be cut down so that portions of the gasket that are not in contact with the engine are removed?

      Hi Camaro Tony,

      You can definitely do that if you wish to – the parts between the flanges don’t do any sealing. The gaskets are all one piece for ease of installation.

    Hi, I have a 351 Cleveland and the exhaust gaskets are both the same. In order for the passenger side to be installed, I need to spin it around which leave the shiny side towards the engine. What do I do in that case?

      Hi Tony,

      The gaskets should be able to be installed with the shiny side facing out on both sides of the engine even though they’re the same shape, is there an area that’s giving you trouble?

          Hi Nick,

          The head gaskets in that set should be Fel-Pro 7733 PT-2 head gaskets. If that is the case, there is no “upside down” to those gaskets. They need to be properly lined up with the head and block castings but it does not matter which side the lacing around the cylinders faces.

          If any head gasket is marked as mentioned in this blog, it must be installed in the direction indicated. Fel-Pro gaskets are application specific, so when they are marked, they are marked properly regardless of if the engine is old, new or in between.

          Don’t apply any type of sealer or adhesive to the head gaskets. Install clean and dry.

          Hi Ramon,

          We see the 1994 Camry had a 2.2L engine, but the 1994 Corolla only had a 1.6L or 1.8L engine. Can you confirm the Model, engine size, and gasket set you’re using for us? That information will allow us to make the best and most accurate suggestion.

          With that said, any Fel-Pro gasket which is not marked directionally and that is symmetrical can be installed either way. The embossment or ridge can face either direction as it creates sealing load on both sides of the gasket.

      Hi Braiden,

      The 3.7L V6 in your 2003 Liberty uses the same head gasket on both sides. The gasket is asymmetrical so all you need to do is line it with properly with the castings.

      Install the exhaust manifold gaskets with the smooth surface facing out, toward the exhaust manifolds. This allows the manifolds to slide as they expand and contract due to thermal expansion.

      Because the gasket is asymmetrical, it will only line up properly with the castings one way. There are alignment dowels in the block that the gasket will fit over.

    I have a 2000 ford windstar and had a shop install a new lower intake manifold. After picking up the vehicle, the oil light came and the rpm’s were low. I looked under the hood and saw that the lower intake gasket had the stamp “front” facing the opposite side of the engine that the belts and pulleys are on. The front side of the gasket facing the back of the motor? What damage could this cause?

    I’ve long had a question about this on Series 2 Buick 3800 engines. For the naturally aspirated engines, you offer a left and a right gasket, 9017pt and 9018pt. The only obvious difference to me is the location of the coolant metering holes. For the supercharged version of this engine, the correct gasket is listed as 9089PT for both sides. I am assuming this gasket needs to be flipped in order to maintain the “front” and the arrow pointed towards the belts for proper coolant circulation/metering…is that correct? The older “left” and “right” gaskets are less expensive and from what I can tell are identical materials/thickness. Is there any advantage to the 9089PT gasket in terms of strength or materials over 9017/9018 to justify the higher pricing? I’m just trying to determine what the actual differences are and which I would be better off using. Thanks!

      Hi Zeph,

      We are guessing you mean the N/A engines use 9917 PT/9918 PT – those are the correct Fel-Pro part numbers for the 3800 Series II naturally aspirated engines.

      The major difference is that the 9089 PT gaskets have a wire ring under the combustion armors to help seal the higher combustion pressures present in the supercharged engines. The supercharged engines are more prone to pre-detonation which causes extremely high cylinder pressure spikes. The wire ring helps the combustion seal hold up better under these conditions.

      Also, the oil return hole shape is different between the 9089 PT & the 9917/9918 PT gaskets.

      One must flip the 9089PT head gasket to maintain the correct coolant hole orientation. The end marked “FRONT” must face the front of the engine, regardless of which side of the gasket is facing up.

    I have the MS 96597 intake manifold set. The lower gaskets have a blue ring seal on one side and not the other side. There are no identifying directions of orientation. Does the blue ring seat to the head or the intake?

      Hi Matt,

      The gaskets are not marked because they can face either direction – they just need to be lined up wth the sealing surfaces. The Printoseal sealing bead is applied at a precise height and width to maximize sealing stress in critical areas. Even though the bead is only applied to one side of the gasket, sealing stress is maximized on both sides of the gasket.

      Hi Johnny,

      The MS 9344 SH intake gasket is the only gasket we offer for this application.

      Because this is an uncoated metal shim gasket, the installation instructions are different than most other Fel-Pro gaskets.

      Make sure the sealing surfaces are clean, dry & straight. We recommend applying brush tack sealant to the intake ports of the gasket on both sides. We also recommend applying RTV on both sides of the water ports of the gasket, as well as where the end seals meet the intake side rails. Torque the manifold in 2 or 3 steps to the final torque.

      Hi Mike,

      When there are no markings and the gaskets are symmetrical, they can be installed either way. The same is true with the 1233 gasket set – the blue Printoseal sealing beads are only applied to one side of these gaskets but the area of concentrated sealing load created exists on both sides of the gaskets. You can install them with the sealing bead facing either direction and they will work just the same. Install the gaskets clean and dry without any RTV or sealer around the ports.

      Install these gaskets dry with no adhesives, sealant or RTV applied to the gaskets. The corners where the end seals meet the intake gaskets will each need a small dab of RTV to seal the joint where the pieces meet.

      Because the gaskets are asymmetrical, just line them up with the castings and you’ll be good to go. It does not matter which way the blue stripes are facing, only that the gaskets are properly lined up.

    got a set of 26415PT Fel-Pro head gaskets for my 2005 Subaru Forester, having a problem wondering if there is different gasket for the left side(drivers side). The ones I got have a R1 in the top left corner of the gasket, The gasket fits fine on the right side (passenger side) but the rivet on the lower left side of the gasket interferes with the head sitting flush it not aligned with the indentations like it is on the right side.

    1. Fel-Pro Blog TeamFel-Pro Blog Team

      Hi Gregory,

      26415 PT fits both sides of the engine. The rivet should be in a location that does not interfere with the installation of the head. The rivet does not end up in that indentation in the block, but it also should not be covered by the head when the head is installed. Have you tried to fit up the heads to see if there is an issue?

      The “R” number on the gasket itself stands for the level of revisions the gasket has gone through. The first time we make a gasket there is no “R” number. As time goes by, the engine design may change or we make improvements or changes to a gasket so now it becomes a “R1.” If we make another revision to the gasket in the future, it will become “R2” and so on.

      The only directional marking you need to worry about on the gasket is the “UP” mark, as that end of the gasket needs to be up toward the top of the engine block.

      http://i.imgur.com/w2sbt0U.png

      The gaskets will only line up on the block one way as long as you match up the gaskets to the casting and the alignment dowels in the block are not damaged.

      We include instructions any time our gaskets require something other than what is outlined by the factory repair manual. If there are not instructions in a Fel-pro gasket set, the contents should be installed exactly as described by the repair manual.

      Factory repair manuals are available in print and online and you can even check your local library as they will often have repair manuals available. If you plan to do other repairs to the vehicle and would rather purchase the repair manual, any auto parts store should be able to order a manual for you.

    Hello, I am installing Fel-pro head gaskets on my 2000 Firebird Trans am with a 5.7 LS1 motor. I am having issues with trying to keep the head gaskets in place. They seem to be curling creating a bowing effect so they will not lay flat. These are the graphite gaskets. They were flat in the packages and no damage happened to them. Do I have a set of defective gaskets or is there a trick to installing these in the car? Please let me know what I am missing here. Thank you.

      Hi Andrew,

      There are alignment dowels at the lower corners of the block that the head bolts pass through. The bowing you’re seeing with the head gaskets is not abnormal, it occurs due to manufacturing tolerances. Some engines will do it and some engines won’t. If it happens, the gaskets will usually bow upwards anywhere from 1/8″ to 1/4″ inch. While it does not look right, once the heads are installed there are no problems. Go ahead and put it together. Just make sure the gasket is lined up on the dowels and that you set the heads on carefully.

      MS 98014 T fits multiple years and applications, so there are two styles of intake end seals included. You will only need one style or the other, depending on your application. Match the end seals ou removed to the matching pair included in the gasket set and set the other pair aside as you will not need them.

      Do not apply RTV to the faces of the gaskets or the end seals themselves. You will need to place a dab or RTV in each of the 4 corners where the intake end seals meet the intake gaskets.

    I recently bought a Felpro head set for a marine engine part # is 17224, for a 305 GM center bolt valve cover. Felpro was recommended by the professionals, When I put the umbrella seals on the exhaust valve I broke every one. When I went to Unapco machine shop he told me that was the wrong umbrella seals because a marine motor has larger diameter exhaust valve stems. At the start of the exhaust stem the size is .340″ and then goes to .3715″ were the seal fits. I was surprize that the wrong seals were in my kit. It cost me $20.00 for new seals. Can you please explain this to me. Thank you and have a great day.

      Hi John,

      Thank you for your patience while we looked into this for you.

      We take it that this is an older marine application? Once the GM engines went to the Vortec, there were no differences in the stem sizes. Is it possible the heads were swapped at some point? We ask because the 3/8” stem diameters were primarily heavy duty truck heads. A major marine engine rebuilder we contacted told us the small block marine engines were usually heavy duty blocks and light duty heads. A 3/8” valve stem adds a lot of valve weight for a higher revving engine.

      If you can get us the year of the engine and the casting numbers of the heads we can look into this even further for you.

      We’re sorry to hear about your troubles and would be happy to help you figure this out!

      Hi Allen,

      Determining the left and right banks on a transversely mounted engine (where engine is mounted sideways, as it is in many FWD vehicles) takes just one extra step.

      Keep in mind that the front of the engine is the end where the crank pulley/harmonic balancer is. Also remember it is the industry standard to refer to the left and right side from the driver’s perspective, while facing forward from inside the car.

      We’ll use a common transversely mounted engine as an example, the GM 3.8L V6 found in many ‘90’s and mid-2000’s GM FWD cars:

      To figure out which bank of cylinders is the left or right bank, imagine this engine in a longitudinal mount configuration, with the harmonic balancer facing the front of the car. The “front” bank of cylinders on the transverse 3.8L engine has become the “left” cylinder bank of the longitudinal engine.

      So in this case, the left bank is the “front” bank of cylinders, closest to the radiator support, and the right bank is the “rear” bank of cylinders, closest to the firewall.

      Because the front of a transversely mounted engine normally faces the right side of the vehicle, a general rule of thumb would be that the front cylinder bank is also the left bank ,and the rear cylinder bank is the right bank.

      Hi Norman,

      It does not matter which side is up in regards to the grommets. The metal sleeve or insert is staked onto the valve cover bolts and cannot be removed, so yes they are reused. The sleeves act as a load stop so the grommets and gaskets are not over-compressed.

      John Gurnig from the Fel-Pro Field Test Gargae has found the easiest way to change the grommets is to chuck the head of the bolt in a vice and use a screwdriver to pry them off, or a pair of side cutters and cut them off. While the bolt is still in the vice, you can work the grommet over the sleeve. Once all the bolts are done, install the gaskets into the covers, take care not to stretch them. Push the gaskets straight down into the cover’s groove. Then you can work the bolts into the cover and gasket. The sleeves fit through the gasket to hold them in place.

      The gaskets are installed clean & dry onto the heads with the exception of applying a dab of RTV at the 4 joints where the timing cover meets the heads.

      We hope this helps!

      Hi Danny,

      The red Printoseal bead can face either the block or the thermostat housing, it sill seal equally well ether way. We apply Printoseal in a specific width and thickness to create an area of high sealing stress, regardless of which way the Printoseal bead is facing.

    Just purchased a 302 V8 for my 1975 mustang ii, the gasket set that came with the engine is a Victor Reinz engine gasket set, there are no markings on the intake manifold gaskets to let me know which side is up, but there is a ridge or lift around the ports on one side of 1 pair of the gaskets 2 pairs came with the kit

      Hi Vincent,

      As mentioned in this post, with Fel-Pro, when a gasket needs to be installed facing a certain direction it will be marked to indicate the direction it needs to face. The embossments or ridge around the ports do not care or matter which way they face. The embossments are there to provide a high pressure sealing area around each port and will do so regardless of which direction the embossments face. Since we did not manufacture the gaskets that came with your engine we cannot be sure that the same applies, but it likely does.

      As for the gasket set having two different pairs of intake gaskets, it’s likely the ones you need to install will depend on coolant port size. Match them up for your engine and do not install the others.

      We hope this helps!

    I purchased a set of Valve Cover Gaskets for a 1984 Chev. Corvette. Part No. VS 12869 T. They still leak oil. The head surface of the engine was cast so not so flat. What other suggestions to stop oil leak?

      Hi John,

      A few questions for you so we can best assist you:

      Were they cast or sheet metal valve covers?
      If sheet metal, were the covers straightened before the installation?
      Are the oil drainbacks clear in the heads?
      Where is the leakage occurring?
      What did you torque the valve covers to?

      These gaskets work best on those heads that have a flat, milled head surface. They will work on a rough, cast surface but everything has to be right to ensure that the rubber is loaded properly onto the heads.

      We hope to hear back from you soon!

        The Valve covers are the original magnesium covers. No cracks in them. The oil drainbacks are clear.
        The oil leaks are occurring mainly from the rear on both sides. I am not sure of the torque specs used. The head surfaces are of the rough cast.
        Thanks for your help,

          Hi John,

          Please place the covers on a known flat surface like a counter top to verify the sealing surfaces are flat and not warped. If they are not flat, check with a machine shop to see if they can true them up.

          Does the rubber look like it has been compressed evenly around the entire gasket? Granted the gaskets will look more compressed at the bolt hole areas. If the gaskets look uncompressed near the ends of the heads, the covers may be bending and not allowing the gaskets to seal.

          Let us know what you find!

    I bought a thermostat gasket part #35251, which has a red ring on one side of the gasket. Is that supposed to face inward toward the engine block, or out toward the removable thermostat housing?

    Reply
    1. Fel-Pro Blog TeamFel-Pro Blog Team

      Hi John,

      The red ring you mention is a precisely applied Printoseal sealing bad – it increases sealing stress by a precise amount in a specific location.

      You can install this gasket with the Printoseal bead facing the block or the thermostat housing, the gasket will seal the same either way. Make sure the sealing surfaces are clean,, flat and free of pitting or other defects. Do not apply RTV or any other sealers or adhesives, this gasket needs to be installed clean and dry.

    When installing the new oil pan gasket (OS30705C) on my 2000 Toyota Corolla CE, should RTV gasket maker also be applied? If so, to which side of the gasket (or both) and just around the outside perimeter of each bolt hole or encircling each bolt hole? For non-gasket applications (other vehicles) I have heard that about a 4mm bead is usual – please advise what size bead to apply (if appropriate).

    Thank you.

      Hi Bob,

      Since you are installing a gasket on an application which was originally sealed with RTV only, first make sure to clean all of the old RTV from both the engine block and oil pan. Make sure the flange of the oil pan is flat – applications sealed with RTV can be tricky to remove and it’s possible for the flange of the oil pan to become slightly warped during removal.

      Since the gasket is now going to be creating the seal instead of RTV, RTV should not be used unless there is a joint created by any component that bolts to the block. If so, a small dab of RTV, on the engine block side only, should be added. Otherwise, install the gasket clean and dry. Make sure to clean the factory RTV from everything, the bolts, the pan, the block and anything else.

    When installing your MS 93856 intake manifold gasket on my 2000 Toyota Corolla CE, while I realize that since there are no directional markings on the gasket it should not matter which way it is mounted, I have to believe that by design Fel-Pro intended the side with the thin, blue, rubbery coating to face either the aluminum manifold or the plastic intake housing.

    Please confirm/verify which way to mount this, or if it really does not matter. If it does matter, then I also recommend that you update your instructions at the very top (unless I mis-read them) to avoid future confusion for others.

      Hi James,

      Look at the seal to see if either side states “air side” or “engine side.” If not, looking at the seal you want to install the seal with the tapered portion of the sealing lip towards the outside of the engine. Do not apply any lube or oil to the sealing lip or crankshaft. You can wipe a light coat of oil to the outside of the seal that fits into the engine to help with installation.

    Hi i have a 2001 dodge dakota 3.9l. I bought part number FEL HS9910PT1. The head gasket works for the drive side but not on passenger side due to the dowel pin location. Looking at the engine block passenger side there is a dowel located at the front upper part of block at the mating surface and there is a dowel at the back lower part of block at the mating surface. that is the same if you are looking at the drivers side of block. If i put the gasket on the passenger side the only way it fits with the dowels holding it in the fire rings will be up side down, that means the dowel hole in the head gasket for the passenger side are in the opposite locations. I installed it like this and the head gasket leaked, there was coolant coming up threw every lower head bolt hole (I used brand new ARP head studs on this application) . I have looked at other manufacturers head gaskets for this specific engine and they are the same as fel-pro they indicate that the gaskets for both sides are identical. But there should be a specific one for driver and passenger side.
    The engine is all stock with stock replacement heads.

      Hi Warren,

      While there is no left or right gasket, it is critical that the oil pressure feed hole is lines up correctly to supply oil to the rocker arms. The head gasket’s dowel holes help to line the gasket up correctly. The engine does not care which way the fire rings or lacing faces – they will seal the cylinders in either direction.

      As for the coolant leak, is the coolant coming up from the head fastener holes? These holes appear to be blind holes, so the studs you installed should not be passing through a water jacket. Can you confirm the source of the leak?

    I am working on a Pontiac super duty 4 cylinder and gaskets have been a problem. The head is a Pontiac super duty aluminum piece. Someone striped all the exhaust header bolts out in the head so I removed the head and it had a fel pro head gasket on it with theFel Pro namel to name side down against the block.. thevmachinest told me that normally that should be up against the head. Head gasket was not blown. I need a new lifter tally cover gasket. But we are having trouble Identifing it. No one has one in stock to compare it is a cork gasket rectangle in shape. It has on the bottom edge a small raised shape to clear the oil pressure sender. Also that four attachment holes had plastic adherents seemed to snap in to the holes. I could be wrong about that. I have purchased an intake gasket number1238-1 and it said some training necessary but not sure where. Also I have purchased head gasket number1015-1should this be installed with the Gel Pro name up or down? Thank you for your help. Bill

      Hi Bill,

      The head gasket will only go on one way because the one corner is cut off. It does not matter if the Fel-Pro logo is up or down – it has nothing to do with how the gasket will seal. Something may have changed in the manufacturing process in regards to where the logo is placed. The machinist is correct when stated about the logo is normally facing up – that’s what he’s used to & remembers, but it won’t affect the sealing.

      We offer two pushrod cover or lifter valley gaskets, PS 13223 C & PS 50153 C. You should compare both to your application and choose the correct one. There are grommets with each set that go on the bolts to help seal them.

      Our statement on trimming the intake gasket, 1238-1, is just that depending on the intake used, machine work done to the head and intake, you may have to trim areas of the gasket or intake ports to make our gasket fit your application.

      As a side note, we would suggest using Time-Serts to repair the threads for the exhaust. They are more pricey but will last longer and are stronger than Heli-coils.

    Hi Guys
    Just received a FElpro oil pan cork gasket set to suit my ’58 Caddy 365′ engine. Do I need to presoak the Front and rear mains seals and can I use some sort of adhesive to hold them in place while I fit the pan?

    Reply
    1. Fel-Pro Blog TeamFel-Pro Blog Team

      Hi Gary,

      If you are referring to the rear main bearing rope seals, no need to soak those in oil. The seals have graphite in them. Before installing the RMB cap apply a light coat of grease on the crank surface where the seal rides. The front seal is a lip seal so it goes in the bore dry, just a apply a light coat of oil on the seal lip.

      The oil pan gasket should be installed on clean & dry surfaces. No need to soak anything in oil. You can use some weatherstrip adhesive to glue the gaskets in place. Use some RTV at the joints where the end seals meet the side rail gaskets. Make sure the oil pan rail is straight. If the areas around the bolt holes look raised from being tightened, use a small ball peen hammer to knock those areas down. Torque the oil pan bolts down starting in the center and work your way out.

      From a 1958 Cadillac service manual,

      Oil Pan Baffle to Crankcase 15-18 ft-lbs
      Oil Pan to Crankcase Screw 10-12 ft-lbs
      Oil Pan to Crankcase Nut 15-18 ft-lbs

      Hi John,

      The seals are installed as you stated – the wider part of the funnel shape faces towards the engine so the valve cover can be slid over the tubes in the heads. If somehow the tube seals are installed backwards, they will still seal, they are just more difficult to get over the tubes.

      Hi Jim,

      When there is a smooth, metallic side to an exhaust manifold gasket, you will want to install the smooth side facing out or toward the exhaust manifold. This allows the manifold to “slide” as it expands and contracts from thermal cycles. This combination intake/exhaust manifold gasket is no different. Install the smooth, metallic side facing outward.

      Hi Ivan,

      That is correct, with the gaskets properly installed (“front” markings facing the front of the engine on both sides) the lettering and lacing on the gaskets may face up or down on either side. As long as the end of the gasket marked “front” is installed to the front of the engine and the castings match up, the gaskets will seal as they’re supposed to.

      Hi Don,

      The 4 plastic rings go in the last bolts at each end of each gasket to hold the gasket to the cylinder heads. They stay there – there’s no way to remove them once the intake is set into place. They will have no effect on the gaskets. Apply no sealer to any of the gaskets.

      Make sure all the sealing surfaces are clean & dry before installing the gaskets. Place a bead of RTV at the 4 corner joints where the end seals meet the side rail gaskets. Install the end seals. Install the side rail gaskets. Add a bit more RTV at the 4 corner joints. Install the intake. Install all the bolts. Tighten the 4 center bolts so the heads just touch the manifold. Tighten these bolts to 25 ft. lbs. Make sure the gaskets have not shifted. If OK, then tighten the rest of the bolts to 25 ft. lbs. Then tighten all the bolts in sequence to 45 ft. lbs.

    I have a stock 1966 Chrysler RB 440 that was rebuilt about 9 years ago and has been driven 300-500 miles per year since. When removing it from storage this spring, I had compression gas entering the cooling system. I thought it would be a blown head gasket, but upon disassembly found them to be intact. The left head gasket was installed upside down – the word “TOP” was stamped on the underside. Could this have caused the problem even though everything appeared okay? There was no coolant in oil, no white smoke, and spark plugs all looked good and the same as each other, and there are no visible cracks in heads or cylinders.

      Hi Barry,

      What helped you determine combustion pressure was entering the cooling system? Was the car overheating?

      Was the cooling system drained each winter? If not, was the coolant a 50/50 mix? Just trying to rule out a cracked head or block.

      Looking the head gasket, I’m not sure if installing the head gasket upside down would cause your particular problem. However, we mark the head gasket that way for a reason. We don’t have a 440 here that we could check the fit on the head gaskets on unfortunately.

        The coolant tested good to -40*F. I drove the car about 45 miles to the storage area in Feb. and picked it up again in April. It did not overheat when I drove it there. When I picked it up again, I had it idling for about 5 minutes to warm it up and coolant was spraying out of the overflow like a fire hose.

        The gaskets look symmetrical, but I assume they are marked TOP for a reason as you stated. I wondered whether there was a different coating on each side for different expansion rates of the heads and block or something on that order. Thank you for your help.

          Barry,

          Take a look at the spark plugs closely, I hope you may have kept them in order. The cylinder(s) that would have had coolant entering them will have very clean, white spark plug tips from the coolant “steam cleaning” the deposits off. Also one or more of the cylinder will have less or no carbon in the combustion chambers. That will help pinpoint which cylinder(s) went bad. If you can determine the cylinders that had a problem, take a close look at the head gasket. These gaskets have a fair amount of coolant ports close to the armors or fire rings. Look for some black carbon across the armor indicating combustion leakage to coolant.

          Take a close look at the “side” of the armors – the face of the armor that faces into the combustion chamber to make sure one has not cracked from detonation.

          If none of that gives you an indication of where the problem lies, use a micrometer to measure the armors in various locations around each cylinder and record them. If you find an area that has been crushed more than others, that could be where the combustion was leaking into the cooling system. The armor had been crushed beyond its recovery and allowed combustion to leak. If that is the case, look at the head & block for a reason of a hotspot – rust, casting flash, etc. – that would have caused this area to run hot.

          We hope this helps, let us know if you have any other questions!

    Hi
    i allways use your gaskets on my ford kent xflow engine, the part number for the gasket is fel8360pt as supplied by burton power england, i have noticed on your gasket there is 4 triangular raised seals which locate around a water way in the head, there is no hole in the middle for water to pass through, i have noticed on other gaskets sold by the same company there are holes in this area, should i make holes through the gasket? or is this the way it was meant to be? obviously i understand this gasket fits many diferent applications hence my question

      Hi Martin,

      There is no need for you to modify the head gasket. Other gasket manufacturers may decide to add these holes. While we closely follow the O.E. design when making gaskets, sometimes during testing we have found that holes may be added, deleted, or moved to better control the coolant flow. Sometimes there may be holes in the head or block that we seal off with the head gasket. The reason for the holes in the block or head is to remove the casting sand when the engine part is first made.

      Back in the 1970’s there were 2 designs of the cylinder head; a cross-flow head and non-cross flow head. It was determined at that time that the holes in the head gasket could be blocked off and work on either design of cylinder head without any problems.

      We hope this helps, let us know if you have any other questions!

      You are correct, it does not make a difference which way the gaskets face top or bottom. As far as front/back, the rocker arm pedestal placement should determine which direction the thicker end of the gasket should go to.

      As the stamping die cuts through the material it slightly rounds the edges but it has nothing to do with which side faces in or out.

    I bought two Fel-Pro head gaskets for my 1996 v6 mustang part number 8857 PT-1 and they have a front stamp at the end of each gasket but it’s impossible to install them both with the same color coating facing upward and the front stamp going towards the front of the engine since they are the same gasket. Should there be a left and right head gasket for all v6 engines? If not do I position one head gasket with the blue stripe facing upward and the other head gasket with the gray coating facing upward so that they both have the front stamp going towards the front of the engine?

      Hi Javier,

      There is no left and right side for these gaskets, and the Blue Stripe side can face the head or the block. You need to install the gasket so the end marked “FRONT” is facing the front of the engine, and so the gasket is properly matched up to the casting, regardless of which side of the gasket is facing up. The gaskets will seal just fine regardless of which side is facing up as long as they’re installed correctly.

          Yes, everything we’ve stated applies to those gaskets as well. Make sure the end marked “FRONT” faces the front of the engine, it does not matter if the blue strips face the heads or the block.

          What is the application with the LS1 engine? If you’re planning to use it in a performance or Heavy Duty application you should consider using MLS gaskets. The only thing to keep in mind is that you’ll need a 60 Ra or smoother surface finish with MLS gaskets.

      Hi Daniel,

      Would you be able to send us the failed gasket for analysis? We’d be happy to send you replacements. This is a Performance gasket and should handle almost anything you can throw at it, so we’d really like to see the failed gaskets.

      Since we do not know all that was done to the engine, we have to ask if you compensated the fuel system to handle the benefits headers add to the engine? If the engine is running lean, the exhaust temps will be too high and could damage the engine as well as the header gaskets. Also, is the timing set properly and have you checked for vacuum leaks?

      We look forward to hearing back from you!

      Hi Evan,

      Generally our gaskets are installed clean and dry, meaning both sealing surfaces must be clean and dry, and no additional sealers, adhesives or RTV are used. Certain gaskets get dabs of RTV in certain locations but it depends on each application. What is the year, make and model of your vehicle, and which gasket set are you installing? We can provide specific advice if we know your application.

      The 26179 PT head gaskets are not marked as they can be installed in either direction where the gasket lines up with the casting. It does not matter if the stripes are facing the head or the block, as long as the gasket is lined up properly with the castings. Install them so they both line up and the alignment dowels are properly positioned. Use no sealers, adhesives or RTV, and follow the factory torque specifications.

    I just installed a set of felpro head bolts on a 6.6 ltr duramax and the torque specs call for 37 lb/ft first pull, 59 lb/ft second pull, 60 degrees third pull and 60 degrees forth and final pull. Out of curiosity I had a bar torque wrench and wanted to see just what torque I was putting of these TTY style bolts. I tried two bolts in torque sequence as recommended and found to torque to be 124 lb/ft, I moved on the numbers 3 and 4 in the sequence and they began to move at 90 lb/ft…….what gives? These bolts should not have moved at 90 lbs if the others set at 124. I put about 15 more degrees on the bolts and they didn’t get any tighter. I found the same situation on three bolts on the others side. These are brand new bolts so my dilemma is, what to do now…any suggestions.

      Hi Donald,

      Actually, this is normal and is exactly how torque to yield bolts work. The purpose of tightening the bolts by a specified number of degrees instead of a certain torque specification is to minimize clamping load variances due to friction during torquing. The bolts are put into their yield zone where they permanently stretch, and continuing to turn the bolt does not apply any more clamping force, as the bolt is stretching. The goal is to end up with more equal clamping force from each bolt – the torque values will vary and cannot be used to determine clamping force with TTY bolts. If you turn the bolt more than the set specification, you could over-stretch the bolts, rendering them unusable. For more information on how TTY bolts work, please read our blog on torque-to-yield bolts here: http://www.felpro-only.com/blog/proper-installation-use-t-t-y-bolts/

      Hi Danny!

      Are you asking why the Victor Reinz set you purchased contains a Fel-Pro gasket? Tooling costs and volumes on various head gaskets determines if a gasket company will make a head gasket (or whatever part). Since we made a head gasket for this John Deere app, Victor Reinz may have decided to just buy it from us. Victor may have made it at one time and they decided not to retool for it when their tool wore out. This happens to all parts suppliers at times.

      Hi Danny!

      The metal side of the gasket goes on the block side.

      Since I don’t know which engine or set you have, I’m not 100% certain there is a silicone sealer applied to the head gasket from us. Please feel the metal side & if it feels slightly sticky/tacky, there is a silicone sealer already applied to the metal side – no other sealer is needed. If the metal side feels smooth, you can apply a spray tack or copper coat to the metal side only. Do not apply anything to the head side of the gasket.

      If you send us the set number you have purchased, I can check this for sure about the silicone sealer.

    Hi, We are replacing the leaking intake gaskets on a 2003 GM 3.4. The engine has not been overheated, but we are also replacing the head gaskets as a preventative measure. Permatorque vs Permatorque Severe Duty? If the Severe duty gaskets have a stronger seal, why not use them all the time?

      Hi Chuck!

      The PermaTorque Severe Duty was developed for delivery vehicles, tow vehicles and other vehicles with engines that operate under high-stress conditions. This of course means they are up to the task of sealing a daily driver. While we agree it is best to use the best possible product while you have everything torn down, it is a matter of what the person wants to pay to repair their vehicle. Some customers prefer to minimize costs as much as possible, so we offer both kits.

      Hi Gregory!

      We need to be clear as to which engine you have in your Mustang. 1993 models came either with the 2.3L, 4 cylinder or 5.0L V8.

      If you or someone has transplanted a 3.8L into your vehicle and you are using 8857 PT-1 it does make a difference how the gaskets are installed. While it does not matter if they go on the right or left bank, it does matter where the coolant holes at the one end of the gaskets are placed. The coolant holes need to go at the rear of each side of the engine. This is to allow the coolant to travel from the front to the rear of the engine and then return to the front of the engine through the heads. By placing the coolant holes at the front , the coolant would “short circuit” and the rear cylinders would overheat due to lack of coolant flow.

      If you have the 5.0L engine in your Mustang, it is the same deal, coolant holes need to go at the rear of the engine.

      The R4 stamp indicates the revision number of this part number.

      Hi Scott!

      You should have a 9917 PT and 9918 PT gasket. The 9917 PT gasket goes on the left bank, or in this case, toward the front of the car. The 9918 PT goes on the right bank, the side facing the firewall in this case.

      The front of the engine is always the end with the harmonic balancer/crank pulley, and the rear is always the end where the flywheel/flexplate is. The end of the gasket with the “FRONT” stamp in it must be installed toward the end of the engine with the crank pulley and belt drive.

      Here is a video of John Gurnig in the Fel-Pro Field Test Garage talking about those exact gaskets. There is other information in the video as to which direction our gaskets should face when being installed.

      Hi Brian!

      The side rail gaskets have the “dimpled” bolt openings to locate and hold the gaskets while installing the manifold. They fit into the 4 of the bolt holes on the heads.

      Blue thread locker or thread tape are acceptable, but not required. You should also apply a drop or two or oil under the bolt heads. The bolt torque is 45 ft. lbs. We recommend reaching the final torque is 2 or 3 steps. Start the torque sequence at the center bolts and work your way out if you don’t have a diagram of the torque sequence.

      No sealer is required on the side rail gaskets or end seals. Apply some RTV where the side rail gaskets meet the end seals.

    Hi,
    Rebuilding a stock 1998 Subaru Outback Legacy 2.5l DOHC engine. While looking for other info on line I stumbled across your “LaserWeld” headgsks. Since I am finding out that these engines have problems with the HG maintaining their seal I am going to pull the heads and replace the new installed HGs with your LaserWeld HGs and use new bolts again. Lesson learned, ought to have used Fel-Pro gsks from the start. Will do so when I rebuilt my other Subrau which also has leaking HGs. Do I have the latest part #’s? Also no sealant on the HGs correct?

    Additional info: The combined amount of material that was removed due to resurfacing the heads and deck was .010″ for each head/deck combination.

      Hi!

      The correct head set is HS 72905 PT-“x.” The “x” will be either PT-1 or PT-2, depending on the engine serial number. The head gaskets, along with most of the gaskets in the set, are the same, but the valve covers are different between the two sets. You can find the breakdown of which serial numbers use which gasket set here: http://www.fme-cat.com/Application.aspx?year=1998&make=SUBARU&model=LEGACY&cat=Engine&subcat=Gaskets%20and%20Sealing%20Systems&ga=Y

      You are correct about needing two of the ES 72905 bolt sets. No sealant should be used on the head gaskets. The total of .010″ between decking the block and milling the heads should not cause any issues as long as they have not been machined before. Just make sure the machine shop knows you plan to use a MLS head gasket, since the original gaskets were not MLS. Fel-Pro MLS gasket require a surface finish of 60 Ra or smoother to seal properly.

      We hope this helps, let us know if you have any other questions!

      Line the gaskets up so they match up with the castings and the contours of the gasket follow the heads/intake. It does not matter which side of the gasket is facing up though.

      We no longer supply the brush tack type sealer in these kits. We found the tubes would sometimes leak, ruining the product. Permatex or Loctite makes a fine sealer called High Tack, it would be best to use.

A complaint I’ve read about this engine was that the lower intake gaskets OEM always would have problems leaking and need to be replaced because they were made of plastic. The Fel-Pro ones in this motor were stainless steel but the replacement set has the plastic/rubber combination.Do I need to be concerned and I’m I going to need to replace them again in 50-80K miles? On the box description of contents the last to items listed are 12-O ring and 1-O ring but doesn’t say for what could you please tell me. And the 6 fuel rail O rings are for the injector to the fuel rail? Why didn”t they include the lower injector O ring where it goes into the intake. Thanks for your time in answering these questions.

      Hi Michael,

      The steel carrier intake gaskets you removed are a premium part that does not come in HS 9071 PT-1. The PermaDryPlus intake gaskets are available in Fel-Pro set MS 98003 T which can be purchased separately. They are also available in HST 9071 PT-1. While we made a lot of improvements to our plastic carrier intake gaskets over the OE style plastic carrier gaskets, they a will not last as long as a PermaDryPlus part.

      This set covers multiple years, and GM used 2 styles of fuel injectors. One style uses the thicker injector O-rings that will cover both ends of the fuel injectors. Later applications use a thinner injector O-ring that goes on the intake side of the injector. The other end of that injector uses the thicker O-ring, so you would use 6 of the 12 thicker O-rings for that side.

      John Gurnig from the Fel-Pro Field Test Garage said the single O-ring could be for 1 of 3 places. It could fit the heater pipe that fits behind the water pump, the heater pipe that fits into the thermostat housing or fit the oil pump drive. I will see if engineering can clarify which location it belongs in on your particular application.

      We hope this helps, thanks for choosing Fel-Pro!

      Hi Dale,

      Are you using Fel-Pro gasket set MS 2853? If so, the direction of this gasket during the installation does not matter as long as the gasket is matched up to the casting. It does not have a top or front.

      Thanks for contacting us!

      Hi Phil, thanks for your post!

      The ES 72856 bolts are not T-T-Y bolts. They get torqued up in 3 steps folowng the proper torque sequence; 25, then 45 and finally 65 ft. lbs.

      The 9111 PT head gasket has two holes for alignment dowels/pins and can only go on one way.

      This image shows the alignment holes:

    Hi, guys. Great service you have here. I’ve got TCS 45996 for my 02 Ram. From your site I learned I’m NOT to use any sealent/adhesive on the timing chain cover to engine block gasket, but should I or can I use RTV on the paper water pump gaskets? Also, what is the included o ring for…the metal return tube that goes in the water pump? Thanks.

      Hi Barry, thanks for your post!

      There’s no need to use RTV on any of the paper gaskets. You can use some high tack to help hold the gaskets in place during the installation if you want to, but it’s not necessary.

      The O-ring is for the heater tube pipe that goes into the water pump.

      Not sure if you have torn this down yet or not, but in case you have not started, Chrysler recommends the use of a special tool that fits into front crankshaft seal hole to correctly align the crank seal to the harmonic balancer. Chrysler does not use any dowel pins for the timing cover’s alignment and therefore you could have the crank seal not centered which will result in a leak.

      You will need to use some RTV where the timing cover/oil pan/block meet. You will also need to apply a thin coat of RTV along the oil pan gasket area that meets the bottom of the timing cover.

      We hope this helps!

    I istaled a fel pro 9661pt in a 2000 toyota engine ,a v20 black / top ,4age JDM engine. I need to know the thickness of the 9661 gasket ,to compair it to the stock gasket that micks .055 thousands. Did the 9661pt lower the compression ratio in my engine? this engine was imported from Japan, parts for this engine are not available in the USA so I was told this gasket would work,and so far it has worked out just fine.Engine has 27,000 miles on a rebuild with no problems. Just wondering about the compression ratio? Thanks for your help Larry

      Hi Larry, thanks for your post!

      Based on the prints, the gasket body is 0.053″ with a 0.008″ armor. Based on my experience, the gasket will have a compressed thickness of around 0.50″. If the stock Toyota is 0.055″ uncompressed, their gasket would have a similar compressed thickness. It’s going to be so close between the 2 gaskets that any change in engine compression is very minor. We design the stock-replacement gaskets to have the same compressed thickness as the OE gasket so compression is not changed on stock rebuilds.

      We hope this helps!

      Hi Benny, thanks for your post!

      This is a press-in-place gasket. Make sure the valve cover is dry before installing the gasket in the groove. Push the gasket straight down into the groove trying not to stretch it. The grommets fit onto the bolts and then slip into the cover to help hold the gasket in place. Make sure the head sealing surfaces are clean & dry. No sealers required. The torque spec for the hold down bolts is 71 to 102 in. lbs. Start in the center and work your way out. I usually torque all the bolts first to 40 in. lbs. and then go to my final torque number.

    I know this has been beat to death, just want to be sure. Installing new Felpro Int. Manifold gaskets on a 3.2L Isuzu Rodeo V6 engine. Using kit MS95751. Number on Int. Man. gaskets is 95814. Gaskets have the blue sealant around the port holes. I’m leaning towards install the “blue” side of the gasket facing up. Is this OK? Thanks for your time.

      That is fine, if the gaskets are not marked to indicate which side is up, they may be installed in either direction as long as the gasket matches up with the castings.

    MS 96679 which side faces the cylinder head? it appears both sides are “shiny”. I notice a rounded edge versus a flat edge. Can you tell me which side is to face the head?

      Hi Nick,

      Thanks for your post!

      This is one of the few exhaust gaskets that it does not matter which side of the gasket faces the exhaust manifold. The only thing to make sure is the flat edge of the exhaust port is on the bottom.

      The rounded edge comes from the when the parts are cut with the die. It tends to roll the material slightly as the die cuts through the material.

    On the VS50244R Vaive cover gasket is there a certain direction. I didn’t notice anything stamoed on the gasket but on side is concaved a little bit and the other side is rounded. Also do I need to apply any type of adhisive or sealer to gasket or cover.

    Thank you for your assistance

      Hi Bill,

      Thanks for your post!

      The gasket will only fit one way due to the placement of the bolt holes at the front & rear of the cover. Make sure both sealing surfaces are clean & dry. Do not use any type of sealer. It may make it easier to install by using an adhesive to hold the gasket to the valve cover. Allow sufficient time for the adhesive to dry as it can act as a lubricant on the rubber gasket & cause it to slip or split. RTV is a sealer, not an adhesive, and should not be used.

      This cover gets torqued to a very low number – 28 in. lbs. Because the cover is so long, try to torque it up in 2 steps.

    I purchased the fel-pro gasket valve cover set, VS 50588 R.

    It comes with both valve cover gaskets and 6 spark plug tube seals….I’m having a difficult time understanding which direction I need to install the spark plug seals in, if the valve cover is laying on its outside face.

    Does the open end of the seal go into the valve cover or the closed end?

      Hi Jason,

      Thanks for your post!

      The open side of the tube seals faces towards the outside of the valve cover. The lip of the tube seal has to be able slide down the tube. If you install the tube seal with the open side facing towards the engine you would have a difficult time installing the cover.

    26229 PT —3.7L Jeep Liberty. Does it make a difference which side is up? one side has slightly raised sealing ridges, back side seams to be slightly depressed in the raised areas?

      Hi Brian,

      Thanks for your post!

      Even though the 26229 PT gasket has a gasket area that seals the timing chain portion of the engine, it is the same gasket on both banks. The embossments (sealing ridges)can face either direction for this application, and it can be installed in either direction as long as it is properly matched up to the casting.

    Which way should a 70262 throttle body gasket be installed on a 5.0L Ford. I assumed it didn’t matter, but I’m getting coolant leaking into the motor through the TB/EGR spacer gasket. Where should the protruding tab be? Thanks!

    Reply
    1. Fel-Pro Blog TeamFel-Pro Blog Team

      Hi Joe,

      Thanks for your post!

      The tab should be facing down.

      72543 is the gasket between the EGR spacer and the intake plenum.

      70262 is the gasket between the throttle body and EGR spacer.

      The EGR spacer should be a sealed unit, meaning the gaskets do not seal coolant. The EGR spacer may have a crack in it.

      Let us know what you find!

    Two Questions:
    HS 8770 PT-1 head gasket for a 2.6 Mitsubishi 1989 I plan on torquing to 69ft/lbs cold then warm engine. After cooled torque to 75ft/lbs. Do I need to check torque later? Is this a non retorque gasket?

    ES 72860 These head bolts look old or used. Is it just a coating? Should I apply a little anti seize to the threads? Will these bolts handle 75 ft/lbs?

    Thanks, Bob O’Brien

      Hi Bob,

      Thanks for your post!

      Mitsubishi has a TSB with a revised torque for this engine. The new torque spec is 80 ft. lbs. – hot or cold. Our gasket does not require a retorque, so once you’ve installed it, there is no need to partially disassemble the engine for a retorque.

      The ES 72860 head bolts do have a protective anti-rust coating that does give the appearance of the bolts looking old. Do not remove this coating.

      You definitely do not want to use anti-seize on the head bolts. The use of anti-seize on the bolts changes the coefficient of friction and will result in the head and gasket being over tightened. I believe the block has blind threaded bolt holes. Please use engine oil on the bolt threads and under the heads of the bolts to correctly install the head & gasket. Just apply a squirt of oil with a squirt can on the threads & under the heads of the bolts/washers.

      Our bolts go through strict testing procedure to ensure the will apply the correct load. They will handle going to 80 ft. lbs.

      Hi Eric,

      Thanks for your post!

      The spark plug tube seals have a “open” side & “closed” side in the way the are molded. The “open” side goes into the valve cover.

      Another way to tell is before you install the tube seal, try to slide it over the tube. Installing it one way the seal will slide on easily, in the other direction the inner lip of the seal will catch and not go on the tube.

      In this application. looking at both sides of the seal, one side is molded “closed” and the other side is “open”. The “open” side goes in towards the engine.

      The 35629 gasket should only line up one way when you go to install it. Install it so the shape of the gasket matches the casting and you’ll be good to go.

    I just recently installed a BS 40619 real main seal on my 95 ford Aereostar 4.0L and it is still leaking. There were no instructions in the box when i bought it. What is the correct way to install it?

      Hi Terry,

      Thanks for your post!

      This is a tricky seal to install and Ford recommends you use their special tools to draw in the seal. They do not recommend using a hammer to drive in the seal.

      First make sure there are no other oil leaks that could appear to be a RMB seal leak such as the valve covers, intake end seal or cam position sensor seal.

      The installation procedure is somewhat lengthy. It would be best to consult a repair manual for the instructions.

      Make sure if you have to remove the RMB seal that the crankshaft sealing surface is not damaged. Make sure that you torque the flywheel bolts to 55 ft. lbs. Over tightening of the flywheel bolts can distort the crank flange sealing surface.

      We hope this helps, and good luck!
