Oil pump hell.

Right, the upshot is,...had lots of oil pressure......replaced oil pump..........can't get new pump to prime or build pressure.......either the relief valve is stuck or the pump
is screwed somehow. Even some "crazy misalignment issue" would still be developing pressure even if it was bleeding some off, it would have to be drastic to not. And
since it is not a B-RB-Hemi, it's not a D'oh!! moment not using a reversible drill. The only things left are His drill is ssloooow, or engine ain't crankin' fast either, but He
ran/primed it in oil out of the car and said it pumped like mad. Bypass valves in oil filters just bleed oil past the filter media when it becomes an obstruction to flow, &
anti drain-back valves are for just that, & I've not seen one stay glued & hold back oil pressure ever. Unless something is wrong w/the pump body casting that is keeping
the pump far away from seating face to face on the mounting surface, shouldn't be hard to spot that......
