I have a oil leak that I cant locate. It is coming from the back of the block, pretty high up. I changed the intake gasket and sealed the ends, but I still have the same leak. I am useing cometic headgaskets, could I be getting oil leaking from there somehow? I should have used felpros but these were recomended. The block was not preped for the cometics. anyone else had this problem?

 

I have cometics and have no issues. I know some people have had head gasket sealing issues with them but I have never hear of oil leaks.
