OK, I just got everything completely apart. Pilot bushing is not as bad as the last one, but it has only been in there a couple of months. The previous one was in there about a year. When I put the end of the alignment tool in the pilot bushing, it wobbles quite a bit. I don't know how much is acceptable. The input shaft bearing is pretty good, I think. I have about 1/8" to 3/32" of side to side play. The transmission was rebuilt about a year and a half ago. The guy that did it was questionable, but it shifts good and it is quiet.
I didn't see any cracks in the bell housing, but I will inspect it further after I clean it up. I will also check the bellhousing alignment before I put everything back together. I will also probably go with a roller pilot bearing instead of the bushing.
Also, I have an oil leak somewhere in the rear of the motor. The area around the rear main seal is dry, the area under the rear intake gasket and underneath the valve covers on boths side are all dry, the rear oil galley plugs are also dry. Is there anywhere else that could be leaking oil? Could the tranny be leaking oil?
