Hello all,
I am helping a buddy put an 87 HO engine in his 68 F/B. We switched to a front sump oil pan, along with a new oil pump and pick up, both from NAPA.
My problem is I can't seem to prime the engine. I put in a total of 5 qts. of oil, prefilled the oil filter, and I am spinning the oil pump shaft in a counter clockwise direction. I have tried turning the oil pump shaft for over 5 min. with an extension and drill, I can see the oil pump shaft is spinning, but after several minutes there is no resistance on the drill, and no oil pressure. (I am using a SW manual guage) Any ideas? I hate to pull the pan, now that the engine is in the car.
Thanks, Rick

Doesn't sound good. Was there any oil in the pump when you installed it? Is the relief valve stuck?

It was a new pump, was I supposed to prime it before I installed it? I guess the pan will need to come off to check the releif valve. Thanks for the response 2+2GT

Probably need to prime the pump. I have read people use vasoline in the impeller gears of the pump to create the initial suction to get it primed.
