This is true! I have a Chrysler 318 that was showing red light flicker at idle after warmed up. I pulled the pan, replaced oil pump and rod bearings. No more red light. BUT-When I installed a digital aftermarket gauge I also discovered 60 pounds cold pressure, and only about ten when hot, possibly even lower when hot and under load, such as hill climbing. The loss of pressure is undoubtedly from the mains and cam bearings, which I should also have changed out. BUT-that brings up an interesting question-since the warning light no longer comes on, how would the average driver know his oil pressure is seriously low?? Or does Chrysler consider ten pounds on the road adequate?? Ted Blackington '55 Imp' 65 Imp.

bearings get worn to a certain point the oil pump can't
maintain sufficient pressure. I've got an old truck [not an
Imperial] that reads 60+ psi cold and 5 psi hot on the
aftermarket gauge.
