I have a 4x4 1995 v8 that has a substantial oil leak that appears to be coming from the top of the bell housing near the distributor. It seems to be in the area of the sending unit. Oil travels down the housing next to the transmission filler tube. Before i start tearing things apart i was hoping someone had some helpful info. thanks in advance.

very possible the sending unit is leaking cheap & easy fix you need a 27MM socket ( i had to get mine machined out) so I recommed getting a oil pressure sending unit socket from a parts store.
