I am trying to get my new motor in this weekend, got it all together, filled it with oil. When I went to prime the motor, I got 60lbs no problem, but it doesn't seem to be getting enough oil to the top end. The rockers are getting oil, but it's just dripping off the rockers onto the springs. I am using an industrial dewalt 1/2 inch drill which has no problem spinning the oil pump. But it does also seem to take alot of power to turn the pump. What should I check? I want to get it in the truck this weekend.
