Obviously, let me clarify, a good oil pump will produce more pressure than a warn out one when hot. 50 lbs of pressure at 300F has to be better than 10Lbs at 300F or 10Lbs at 180F for that matter....right?
At some point the oil is just too hot no matter what pressure it's at. I just want to know how hot that is?
Or is it that the expansion of some internal parts will become so great that no amount of lubrication will prevent seisure?
