make sure the oil is not coming from the oil return tubes. oil leaks can be a tricky chameleon. if you have a B.A.O.S (big a$$ oil spot) on the ground, i bet it is the return tubes. i was fooled not once but three times, but i am an optimist. "no way, it is the oil return tubes, please be the easy to change valve cover gaskets, PLEASE!" damn! (someone once asked, "how many oil return tubes does your car have? i was asking about them that much)
