Valve Cover leaks...help!!
 

Ok, here is my question. I just did my engine rebuild about 6,000 or 7,000 miles ago...and my driver's side valve cover is leaking in the back. This ticks me off. I want to know if anyone knows where I can get RUBBER valve cover gaskets. I used to have this problem on my camaro until I switched from cork to rubber gaskets. They are really nice!! I have GT-40P heads, so do I ask for '98 Explorer gaskets, or '89 Mustang gaskets??? Josh

Not too sure which to ask for, but I got rubber gaskets from AutoZone for about $10, and have reused them at least 3 times with no leaks.

autozone says they don't have rubber gaskets for my car, or the '98 explorer. they only have cork. I checked on carparts.com, and they have some RED LINE VALVE COVER GASKETS for like $11.69 a piece, and it says they are a 5/16" cork/rubber material, "good for even those thin factory valve covers" which i still have. Any input on these gaskets? Are these the rubber ones I'm looking for?

Clean your valve cover gasket face real good.
Apply a medium film of blue RTV on the valve cover. press the cork gasket itno place and install. Your gasket is moving around after you run you car up to temp a few times,this will help put a stop to that.
