Default Valve cover gaskets

Which v/c gaskets do you guys use on your center bolt heads? It seems to be a pita re-installing the typical reusable rubber gasket when valve lash have to check every now and then. Is there a different kind of gasket out there that is easier to re-install and yet seal just as good?

I solved this problem by RTVing one side of the gasket to the valve cover itself. Put a THIN bead around the trough of the valve cover and set the gasket in. It should be thin enough so it doesn't squish out and look like crap. Once it's set in, installing the VCs is MUCH easier.

Thanks man, but I have done this, and have to do them each and every time I take the valve covers off. There's got to be a better solution to this.

I've used the same rubber gaskets for like 9 years, but only removed them 4 x. New valve covers, 1.52's, 1.6's and 1.7's, so far. I would think cleaning them and using the good rtv on one side would work well.

I use the cork type, I think Fel Pro brand. They are stuck to the valve cover with an adhesive and I have had them off many times and they always seal good.

The blue gaskets work fine and stay in the valve cover when I take them off.

My valve covers have orange seals (they were on the motor when I got the car), they fit snugly in the grooves and have never leaked, opened them numerous times for valve lash and checking head torque after heat cycles after the heads were off.

I've noticed the seals themselves have a groove too to sit on the walls of the heads for sealing.

I use cork too.. Only problem is they started leaking when I was using the sauce. Too much crankcase pressure I suppose. Otherwise, I have had the best luck with cork gaskets. Always stick to the valve cover (with the help of an adhesive) and don't leak.

I've had great success putting a dab of Ultra Black on all four corners of the valve cover and inserting the gasket.

How often are you setting your valve lash? Poly locks might help...

Since I am boosted I have to be careful of valve cover leaks and I use a composite cork they aren't cheap ~$50. The composite cork gaskets seal well but are a royal pain in the ***.

Forgot to add when I get new gaskets I always stretch them out before putting them on the valve covers. I stretch them until there is a little bit of slack.

RTV doesnt work so good, clean the covers with alcohol and use 3M weatherstrip adhesive to glue them to the cover. Use a light coat of white lithium grease to stop them from sticking to the head.

Thanks, that's another good suggestion. Will have to try this one next time I open the valve covers up.
