Dumn, I did it to myself again, best guess. I dropped the pan and pulled the oil pump out. The piston on the pump didn't appear stuck. I could move it, though it took a little more effort than maybe it should have. I removed the relief valve and it is possible to reverse it. I checked the factory manual and the piston it shows for the valve is different than the one I have. The manual shows a cylinder. What I have is hollow cylinder with one end closed and tapered to a 3/16 shaft about a 1/2 in. long. I had the shaft in the oil passage. I reassembled it with the cupped end in the oil passage. With the cupped end in the passage I'm thinking I should get more force on the spring. Anyone familiar with with oil pump relief valve?
