My tappet blocks were not leaking before, but since I have replaced the head gaskets, reinstalled the heads and camshafts, they now appear to be leaking a small amount of oil. This is before I have even reinstalled the camshaft covers. The tappet blocks were not removed from the heads.
How likely is it that they would now be leaking even without the engine not reassembled? Am I imagining this?
Thank you in advance for your advice. This group has been very, very helpful with my head gasket replacement project.
