Next dumb question...are you sure your turning the pump the right direction? I’d run it both ways for awhile. Won’t hurt anything to run it backwards. Did you run it long enough to pick up the oil? Maybe try over filling the crankcase with some extra oil. You can always drain it back out later.
Yes, pump is being turned CCW, and yes, I've tried running clockwise as well.
I definitely didn't remove oil, and if it leaked out, it would be obvious on the gravel underneath the car. But there is plenty of oil on the dipstick.
My plan for this weekend is to overfill the oil a bit and see if the situation changes. If no change, I'll drain all the oil and stick my endoscope through the drain plug hole to visually inspect the oil pump. Perhaps remove the oil filter housing and blow compressed air through the oil valley to see if the oil pump "gear" on top will spin via air pressure. Then, add oil back and see if any change in the situation.
