  • sealingf valve covers?

    I did the valve cover gaskets and when I started it up and took it around the block it was smoking alot so I am assuming they didnt seal. they are at a wierd angle. so how do you seal them? any help would be great. thanks.

        well, mine haven't leaked yet from the engine cranking, but I did make sure all sealing surfaces were clean and that the noodle seal ws seated good in the valve cover before tightening down. yours are tightened down enough, right?

          yes I am pretty sure but tommorow I will tighten them up and try to see what was going on it is just such a pain to do the cover. but it will be easier because I left the engine lift bracket off.

            You may have just spilled a little oil when you did the change.... if so it should burn off after a few minutes of running.

              Vavle covers can be a major PITA leak if done improperly. You can ensure a leak free seal.

              Here is what I have always done in the past with great sucess.

              When vavle covers are removed I totally clean the surfaces of both the vavle covers and the heads. I mean spotless. Then I take a rag with alcohol and wipe both surfaces down.

              When dry I apply a small bead of Permatex along the valve cover.

              I spread this evenly with my finger.

              Then I apply the gasket to the vavle cover. (When possible i always choose cork....seems like most people prefer rubber but not me. Cork has nver failed me yet.)

              I let this set up for a 5 to 10 minutes.

              Next I apply the permatex to the heads. Again don't go overboard just enough so that you can spread it evenly across the surface with your finger.

              Then I set the valve covers on the head and tighten the covers down slowly in even steps.

              I will let this set for about an hour before firing the engine.

              This may or may not be the way vavle covers are done by everyone else but like I said I have yet to ever have vavle covers leak on me yet.

              Hope this helps.

                cork, for the 3800 valve covers?........

                On the 2.8~3.4 engines I cain see that. Maybe you just looked at my screen name and...but yeah, for conventional valve cover gaskets you have some good advice.
