Just finished assembling engine after head job and basically new everything. After running the engine, there is an oil leak coming from the intake manifold. The reason I know is the in-take manifold is because I took it off the head and there was oil around the gasket as well as the intake. The question I have is, I know that oil does come up to the rocker assembly, but is there suppose to be oil inside the intake. Is not that much, but enough to where is sliping through the intake manifold down to the header and to the floor. I am replacing the manifold studs as they are worn out from taking them off so many times. I'm not sure if tighting the manifold studs will stop the car from leaking. Any suggestions will be greatly appreciated.
