So update wise how is your oil pressure? How is the sensor? To me sounds as bad oil really, or deposits left behind by a bad one or maybe oil stat was not changed in time. How many miles are we talking about here? What engine? Some engines oil pump is chain driven internally by crankshaft when pump chain gets to much slack makes it sound like this but not the warning you ae getting. Might be a silly questikn and please be excused if so but if cartridge type oil filter, was it sitted properly? A lot of people miss on this and most of times the engine does not get full oil flow...other cases it starves it of oil( the fact that oil levem is the same before cold start and after 5 minutes with hot engine made think to this)

Note: sorry for the bad typing, issues wigh the screen.
