What is the general concensus regarding the brand/style of valve cover gaskets to use on either the n/a or */c 3.8'*? I have one of each in the garage and both are begging for new gaskets. I am thinking the GM'* aren't all that great considering the common failure rate, but maybe they're the best of what'* available???? Help.....
I've used both factory parts and Fel Pro'*. Both will fail with enough time. What haqppens is the rubber seems to flatten out with enough heat cycles etc. Swaps are inevitable..probably somewhere around the 7+ year or 100K mile range.
I recently pulled mine for some work. Have had them 2-3 years and they looked ok. Not wanting to have a future leak and knowing I'd be dinking around in there some more, I replaced them again and don't have a leak.
Overall my thought is Fel Pro probably makes them for GM. There doesn't appear to be any differences except the prices.

Thanks for the input fellas. I have had that happen in the past when you pull the Fel-Pro gaskets out of the box and lay them next to the GM'* and struggle to find any difference between them other than the $$$. I have noticed that the */c cars seem (IMO) to blow these gaskets easier than the n/a cars. Are we getting too much positive crankcase pressure? Would a valve cover breather be in order?
I replaced the PVC earlier this year as part of my tune up regiment. Since then, the leak at the gaskets hasn't appeared to have slowed. I've degrease the areas a few times in an effort to get a feel for how bad the gaskets are seeping, and it'* bad enough to warrant replacement. I guess it'* time to bite the bullet and get some gaskets.
