360 oiling problem under load

Uh huh. :D

Maybe not hot or cold, but for sure in neutral.

Everything I'm reading is telling me it's a cavitation issue with the pump (like it's sucking air), but you would think it would also do the same in neutral.
Thats whats getting me even more frustrated. No metal in filter kinda rules out bearings. No problems in neatral revving as hi or as long as i want. ONLY in gear under a load at operating temp. If i had hair id be pulling it all out about now! If i had a dummy light instead of a gauge, id never even know this is happening and id probably be picking parts out of the pan by now
