The noise doesn’t happen all the time like it used to, just in the 2000-4000rpm range still.
Only on partial throttle past half in that band no noise. Even with the oil pressure low. But partial throttle sounds like a couple of aliens in my engine bay taking cast iron pans to my motor.
Could this be a bad oil pump? What else would cause the sudden drop? I replaced the oil gallery already
