I have found I have a rms leak. I have the engine out now and found at some point some one has replaced the rear main seal. It appears that instead of dropping the pan and removing the rear seal housing to replace it they used a seal pic. There was a scratch in the seal surface on the crankshaft. I very very carefully used some 600 emery cloth to clean it up. If this does not work does anyone know if they make a ready sleave for the 1piece rear main seal type crankshafts????
