I built my motor and when I broke it in I found oil pooling up on the block right behing the driverside head. First thought it was the intake changed the gaskets and the leak is still there. if the head gasket isn't sealed good enough can it seep oil? I'm running out of options here. Thanks for the help. Oh, I used summit metal/felt gaskets and i sprayed the metal side w copper spray-a-gasket.
