Finally got around to inspecting the oil pump.
There are some rub marks on the cover plate from the driven gear, but nothing that I could feel with my finger. Most likely a surface thing. I found the clearance between the driven gear is less than 0.004", but the other gear is greater than 0.004". Hard to get an idea of the lash between the gears since my feeler gauge is a bit wide to fit, but from what I could measure, it seems a bit loose or at least approaching the edge.
Guess I will buy a new oil pump and be done with it.
