The Stovebolt Site Forums The Shop Area Engine Shop oil pressure

Hello All;
thanks for the replys, so her is an update:
I took the lifter cover off and checked the oil line that goes to the head and found a kink in the line, so I go to the hardware store to get some 3/16" line, and that was a no go, so off to NAPA (should have gone there first.
Anyways, I took a shaft from a spare distributor and attached it to my drill to prime the engine, VIOLA, instant 35 psi, and with the drill slowly turning I had 20 psi (55 degrere day, oil cold and using 40W) with the oil line disconnected.
So my question is, why do I have higher oil pressure using a drill, with the engine not running?
I would think the oil pump would prime itself with the engine running.......
