Just put on a new set of valve covers and gasktets on the '82 and they leak. I have the finned Edelbrock covers with the chorme hold downs and the fancy rubber Fel-Pro gaskets. They leak comes from below the bolt holes and makes sort of a U shape in between my manifold pipes. I forgot to oil the gasket when I put them on. I tightened them up pretty good too, tight as I could go with one hand on the ratchet, maybe too tight. I didn't use any RTV because Fel-Pro said not to. I had some smoke from the manifold on the passengers side after I got it home. I tightened the cover and it seemed to stop. Man these little problems are starting to drive me nuts. Two lanes wide, twelve yards long, sixty-five tons of American pride....Canyanero!
