[QUOTE="Jdgriffith30, post: 427859, member: 19295"] Hello. I am trying to determine the source of an oil leak. I get about 1-2 tspns on the ground right after driving. I replace the rear main seal twice but still have the leak. I just dropped the oil pan again and see that the flange that connects the crankshaft to the flywheel is perfectly clean, and so is the front of the flywheel when I look into the hole of the bell housing cover after removing starter. Does lack of oil on these parts confirm that it is not the rear main seal? Thank you, John [/QUOTE]
