Low or no oil pressure on new engine, wtf now...

It's very possible the first cam eating deal put metal into the oil system. Something could have gotten into the new pump. but I'd be looking for 40-50psi cold and a max of 75psi at like 2000 rpm with that pump.

Well, it had low pressure from first crank, it never went up past 20 psi. Still working to see if its the gauge, but pulling the line while running and seeing how slow the oil was moving doesn't give me much hope on the gauge.

Just confirmed the distributor oil plug is there.
