Valve Cover Oil Leaks

Awesome. This is super helpful, thanks.

If I were to use the ribbed rubber gaskets, do they require the same process (sealing to vc)? Or would you just put them on dry - both sides?

Good question.
Ive had a set of those on the wall for years (Mopar Performance), that im finally going to try.
Im under the impression that you put those on dry. Racers use them to pop the VC on and off.
So, we will see.

Save your self some cash, and use the Felpro cork gasket with the advice I gave you.
You should be good. PS: Dont over torque them. Follow the factory torque/sequence.
