Timing Cover Gasket Sets
#1
Hi, what is the difference between Timing Cover Gasket sets 45121 and 45265 to be used on a 1976 Corvette with a Stock 350 cu/in engine. When would I need to use 45265? Also, do any of the timing cover gaskets require RTV? Does it hurt to use RTV no them?

Hi,

TCS 45121 and TCS 45265 both fit your 1976 Corvette. The difference is that TCS 45265 includes a repair sleeve and locking compound (for the sleeve) to repair wear to the harmonic balancer. If you do not need the repair sleeve, then you would want to use TCS 45121.

RTV should only be applied at the joint formed where the timing cover gasket meets the oil pan gasket. Use only enough to fill the joints, if too much RTV is used it can cause the gaskets to slip or split during torquing or chunks of RTV could fall into the oil pan. No RTV should be applied to the gaskets, block, or timing cover in any other locations.

Ok, thanks. Where do I look for the potential wear on the harmonic balancer?

Carefully inspect the sealing area for a groove that may be worn into it where the seal rested.

Here is the instruction sheet included in TCS 45265, the illustration is pretty basic but should clear things up:

Hi,

Are you looking for a thread locking compound? If so, choose a medium strength compound from a reputable, name-brand company.
