Timing cover gasket

[SAndreasen]

Why do the gasket sets from aftermarket not with a gasket for the front cover

Most people just use rtv

I use "The Right Stuff" by Permatex. Never a failure with it!!!

We use Ultra Gray at the shop and I have it on mine, too. When I replaced my front crank seal the second time I used a Cummins gasket. It never did seal totally. The 3rd time I used Ultra Gray and haven’t seen a drip since.

This is from the Cummins SM. Evidently there’s an aluminum gear cover that takes a gasket but you’re to use sealer on the stamped steel cover.

Thanks . I used a gasket we stole out of my buddies engine kit which is a felpro and loctite 515 I don’t think I’ve ever had anything when I’ve used 515

The Three-Bond sealent mentioned for the 24 valve engines is amazing stuff. I think it was developed in Japan for high heat and vibration applications which may or may not use a gasket. I used it to seal an oil pan gasket on a Chrysler minivan's 3.8 V6 that had a leek at a triple junction where two aluminum alloys met the steel oil pan. The doggone stuff turned that engine into a well-trained puppy. Three-Bond can be difficult to find and it has an aggressive shelf life. It has a consistency slightly more viscous than water. That sounds bad but is actually good. Unlike regular RTV, it won't squeeze out and get into internals. I t's worth the trouble.
