Once warm my oil pressure falls below 10psi and the green light comes on at idle.
I feel hot air coming out the oil fill. So I suspect the oil is getting frothy and not able to do it's job.
I have carbs. Timing is adjusted to Pelical artical recommended 34ish* BTDC.
Maybe that's too much?
Just did an oil change to try to remedy this. It's not buring oil.
