Hi I'm rebuilding an ford 9n. I'm 15 doing this as a winter project but winters over so its gotta live . I put a new starter, rings, valves, rod bearings,manifold, muffler, entire eletrick system on it new carb to. I've got 95 lbs compression through the board. 3 weeks ago I had it running perfect, I put about 5 hours on it letting it Break in but I had only 15-20 lbs oil pressure. Come to find my oil pickup tube was loose so I replaced the tube, pulled the pump out but everything was tight so I put it back on. I only tightened main oil pump cap to 80 lbs. 90-100 seemed really tight for the old machine. Hand spinning the engine it doesn't hit anything. When I touch the starter it makes a thumping sound not like before. The oil pans off it now with it on bricks. Any idea what the problem is?[/quote]
