Get rid of them I went through that fiasco with them in the past , should o f had wing nuts been on & off so many times with different gaskets & bases , get Teague cover,s .

I had good luck with mine I silicone them to the head with no gasket.

They SUCK !!!!!
I have 4 sets for sale lol

I've only dealt with one set about 5 yrs ago but I remember it was really difficult to get the o-rings to fit right. I ended up using silicone grease and they finally went into their grooves but it was a battle. Since then they have not leaked a drop.

I will try some more grease but I tryed that a couple of times I am wondering if there leaking between the head and lower base panel not the cover its self?? They leak so slow and constant I just cant find eaxcutly where the oil is coming from Jim

also,w/ the o-rings,try to get betw the o-ring and the valve cover w/ a pick and go around a couple of times.this should untwist the o-ring and help it go in properly.as your turning the nuts down,tap lightly side to side and top and bottom repeatedly as you tighten up the nuts,at 1 point the cover should just pop in.

He also needs to check out your grinding mod.

Silicone grease is also what I was using. It was the ford brake grease. Very thick.

Has anyone using the new design I was told they fixed the proplem. I been itching to buy them but don't want to go threw the hassle. . If they fixed them I will buy them..I call and they said KE fixed the proplem but would like to hear first hand.. ANYONE.....

The new covers work good.
