June 6, 201115 yr comment_529965 The oil pump wears away all the time, as do the bearings, so oil pressure drops as the motor ages, less oil gets right around the motor. Upgrading the pump restores some of the lost pressure. I'm not sure how much difference the washer under the spring makes, I suspect it does SFA. Cold, 65pi wouldn't be amiss, warm about 40 and down to 7-10 on warm idle from my old Mini Cooper days. Haven't had a decent oil pressure gauge since then. Report
