Can't say for sure about the rear main bearing but it was leaking prior to the rebuild and after the rebuild so I guess it is possible!!
Same thing goes for the sleeve not sure but the powdered stuff was put underneath it that was suppose to seal it but it does appear that it's the seal. From an eyeball view it appears that the crankshaft is not centered inside the seal but my old eyes ain't what they use to be!! Thanks for the replies!!
