There is a steady drip off the oil pressure sending unit on the 84SD. It looks like the sending unit is 2 made from pieces crimped together. The FSM says this is an electric gauge. Is the leak likely to be at the crimp or where the electric connection screws in or at a gasket? Should I just pull the oil filter housing to be done? Is this a crawl in the gravel job or would a lift make it multiple times easier?

It looks like the valve cover gasket is going to leak (again). I'll follow these directions next.
