Topic: Valve Cover Gasket

[Jeffy]

Seems mine is leaking a bit.  It doesn't look like there is a cork gasket but rather some grey RTV from the factory.  So should I use RTV Blue or do I need Red?  Or buy the fel-pro cork gasket?

I used RTV on mine and it is no longer leaking.  But I forget which one I used.

Blue is the regular one, I think.  Then there's Ultra Blue which, is higher temp and then there is red.

I guess if they use grey then going with Ultra Blue should be fine.  Saves me the hassle of going to the auto parts store.  I always keep a tube of Ultra blue around.

i think the 94-95 was a rubber gasket.

OK, mine HAS a rubber gasket, but I had to use RTV because the gasket alone leaks...

I've put a cork gasket on a pre '91 before but after looking at mine, I can see the grey RTV.

you could use black RTV, would work just fine (silicone is heat resistant, red would be overkill for the valve cover imo + it sticks out like a sore thumb)

I used the Black RTV with the factory rubber gasket.  Seems to be Ok.

Use the no leak stuff, grey, blue black or red take your pick. The regular RTV will work but if there is any oil or grease left it will leak there. The no leak stuff is the bomb, for pretty go with gray or black

I used the regular Blue and have had no troubles.

Yeah, even the Permetex Blue seems to be OK for valve covers.  I usually go with the Ultra Blue since it's better then OE/Grey/Black or Blue.  The only 'problem' is that it's blue.

It's to bad your not Swink. Seems like all his stuff was painted blue.

I had to repaint my shackles because of that.  The bushings ARE blue though.  (they're from Swink)

I use Ultra Black on pretty much everything.

i however if you want a super strong silicone that can even seal cracks permatex makes something called The Right Stuff

we use The Right Stuff on just about everything... going to use it on my leaky valve cover when i get some time.
