Valve cover gasket set recommendation needed
Can anyone recommend one type of valve cover gasket set over another?
Some gaskets have the silicone bead around them, others are graphited. Can any of you gurus call out a preferance and explain why? Thanks in advance...

gray uppers and lowers. they're thick, so they take up most surface irregularities in the covers. silicone rubber ones are kind of wierd, being that you can't really tighten them much or they will squish out.

I used the gaskets with the silicone bead and never had a leak in three years.

The intake ones don't matter-anything will work. For the exhaust I highly recommend the green ones with the silicon bead around them. I've never had a leak with them. The pure silicon ones that JW is talking about can be hard to use and I don't like them. As he said they tend to squish out. Others have had good luck with them however and they are reusable.
The last couple of kits I bought had gray graphite uppers and the green lowers with the silicon bead. I ask for these now whenever I order. -Andy

red silicone gaskets on the lower. If installed right they will cover up many other flaws (warped covers) that the other gaskets won't. plus they are re-useable. All you have to do is clean the surfaces and the gaskets and tighten them down a little bit. Not alot, only about 3 ft. lbs.

I've had excellent results with the gaskets from this outfit.
http://www.realgaskets.com/ They supply porsche gaskets here. http://www.realgaskets.com/files/automobile.htm#porsche I've had them for a year now and nary a drop of oil if torqued correctly. And they are also reusable.
