Oil pump was a rebuilt from NAPA. Of the last three waterpumps that I've replaced, two of them were bad out of the box, so a bad rebuilt oil pump wouldn't surprize me.

Here is something I need a second opinion on; When I dropped the main caps the bearings were soaked in oil but there was evident scoreing in the seat of the bearing with the rest of the bearing almost untouched. My friend says that's obvious oil starvation. Now I don't know what kind of gap should be evident between the bearing and crank but I see a gap between the end of the upper bearing and the crank big enough I could stick a matchbox cover in it. My gut says that's wrong. I know, I know, My gut is no substitute for plastigauge.
