On a new gasket installation (or fresh engine) with a cork gasket it usually is required to retighten the bolts at least one time.

If found loose snug them up and clean the engine at a coin wash.

THEN see where the leak comes from if still leaking. Don’t continue to drive it.
Windage will surely spread the oil around.


I did check the nuts on the oil pan at first and they were a little loose so I tightened them up two more separate times and the pan still leaked after snuging them up. I pulled the pan off anyway to change the rear main seal that is also leaking. Is there a certain torque spec for the oil pan bolts and the rear main seal retainer as well?
