4.0 mystery leak
1994 4.0, had the infamous oil adapter leak, changed it to the block mount filter set up. The the oil pressure sending unit started leaking, changed it. Now there is a squirting leak that appears to be coming from the front of the block molding for the oil filter, but without pulling the mount and everything on the passenger side I can't see it. Any idea on this?

Sure eliminating the oil filter adapter didn't allow a motor mount piece to contact the oil filter?

maybe you cross threaded the filter or the threads on the filter are bottoming out before the seal seats properly, not common, but ive seen it before

No contact to filter and no cross thread. Filter seems like its set good, I think pulling the motor mount I'll be able to see the issue

Long time past but it turned out that there was a small piece of gasket stuck on the surface of the block causing the leak.
