I cleaned the area of the crankshaft where the seal runs but I did not polish it. How would I go about polishing it?
I also cleaned the recess where the upper half of the seal inserts by feeding a small flexible brush and brushing back and forth.
The seals were put in with the end(s) offset 3/8" so they did not line up with the ends of the cap and block. The end of the seal halves had RTV sealant added. I also put it on the surface of the cap.
I'm about 100% sure it is the rear main seal that is leaking. The valve cover gasket and the side pushrod covers also have had the gaskets replaced. All is completely dry around those areas. When I replaced the rear seal, I obviously had to replace the oil pan gasket. All is dry around that as well. The only place there is oil is on the inside of the flywheel cover, which is then dripping on the ground from the hole in the bottom of the cover.
