Thanks for the responses!
I know about the stuck relief valve. This block was supposedly rebuilt, with about 10k on it, when I got it. One of cylinder was scored real bad, but the piston looked perfect considering 10k. Anyway had it bored, put it back together used same oil pump. Primed the oil till I felt the drill start to really work. I have a mechanical oil gauge I keep in the tool box for when I first start a motor that's all the use it gets. I always put it on a motor when I first start it. The oil gauge read 80# plus on the prime, OK the drill turns fast. When I started it blew the oil filter gasket, OK maybe I didn't tighten it enough. I put another filter on same thing. (Think I posted that here.) I bought another pump standard replacement made by Mellings. This time when I primed it, it went to 80# and held.
I hooked up the oil gauge the previous owner installed it goes to 80# and is mechanical also, today. I get a different reading a bit over 40#. Maybe I blew more than the oil filter gaskets. I'll have to check the gauge in tool box and see if it reads good, now.
