Default Re: Rear Main Leak Bear with me

The main bearing leak from excessive clearance or crankshaft end play will leak at the back of the bearing cap and follow the contour of the cap to the front.rear main bearing bolts should be sealed with rtv as part of assembly.Wash the area with brake clean and idle the engine,lay under and watch the area,if the oil doesn't track from the flywheel side of the bearing forward to the pan cork it is migrating through the main bearing bolt hole.
