Well sorry guys I should have looked closer. The oil sending unit is NOT on the base of the oil filter pedestal on this engine. This 2F came out of a stock‘76 fj55. I just figured it was identical to my ‘77 fj40 2f. So I’m going to clean it real good and install a stock oil sending unit in that...
Thanks for the help guys. This is a first start on engine that hasn’t run in awhile. New head gasket etc. No coolant in the engine currently. I was thinking and hoping it was oil passage way but wanted to be sure. Best plan of attack to tap it and plug or is there a crush plug like a frost plug...
