What is a good valve cover gasket to use?
 
I have a 90 YJ with 4.2L. I've replaced the valve cover gasket several times over the 17 years I've owned it. I've always used the cork gaskets bought at the local parts stores but have always ended up with the same results. They deteriorate quickly and start leaking lots of oil. What is a good replacement gasket that you guys have used that has held up better than the cork gasket?

FYI: I have the aluminum cover, not the plastic one.

Thanks

I like the blue FelPro one, that's basically a metal core with a rubberized coating. I also have the aluminum cover on a 4.2.

This. It's more expensive but well worth it IMO.

I think you have your answer. I've tried the crap in a tube and the cheap cork as well with similar results. I've used the felpro for several years now, and even reused it several times when I had to remove the valve cover. It keeps working and at this point has paid for itself.

I use the cheapie cork gaskets with no sealant. When it's time to replace, it gives me the excuse/opportunity to inspect the rockers, springs, etc. Same with the oil pan and diff covers. Unlike most vehicles, these are easy to access and replace. I don't use sealant because I don't like cleaning that **** off of everything it touches.

Lube lockers are great for the diffs. I installed mine over two years ago and have seen a drop from either one. Way I see it, if you're going to be checking on things anyways, why not used a gasket that'll last so you don't have keep spending money on them lol.

I've been considering those for my diffs simply because the pan comes off to change the lube regardless of leakage. :thumbsup:
