My car had a leak from the mating surface of the oil pump. Someone in the past had removed the oil pump and used a screw driver or other tool to pry off the pump and put a shallow gouge on the mating face of the pump. I removed the pump and had a bead of weld applied to the gouge and then had an automotive machine shop mill the surface perfectly flat again, then reinstalled the pump.
