All main bearings plastigauge at .002
Rod bearings #’s 1-2-3 at .002
4 & 5 at .006 and # 6 at .002.

Going to reinspect crank jurnal and install .004 under rod bearings, plastigauge adding to verify .002 gap.
Close it up and heat cycle the motor. Fingers crossed

That does not sound like that much excess clearances for that much oil loss, but you never know. I have not had to face that situation myself. - If I had found this extra 0.004" on a couple journals on my own engine, I would have wanted it fixed too though, even if that was not the issue.

All I can say is that this is likely the most thorough discussion about oil pressure loss issues that I have seen so far. Maybe when you finally solve it, then it will help others out there who may end up with a similar problem.
