I recently posted about an odd oil leak I have seaping up out of my intake gasket where the head meets the runners . Everyone kept mentioning valve covers and such but they are all good. I got the intake off to find oil seeping out and the entire side of the engine has been building it up for years . My question is , should oil be in these valleys ? I see that the intake manifold blocks off those valleys between the runners but the intake seal has cutouts for these valleys , I'm guessing to keep oil from seeping . I've done compression tests and I've had no signs of a bad head gasket . So could it simply be the intake gasket ??
