Erratic oil pressure is usually caused by a bad oil pressure sensor.
-faulty oil pres. sending unit -faulty oil pump
oil pressure is directly related to engine rpm. more rpm = more oil pressure. the oil pump is driven off of the camshaft or distributor.
oil pressure normally will go up and down with rms for the most part. when the motor is cold there is more oil pressure as the oil and motor get warmed up the oil thins out and the pressure goes down.
Low oil, no oil pressure, bad sending unit, wiring, bad gauge,.............
my oil pressure goes up while I'm driving and back down when I stop what could cause that
the oil gets cloged up. Try vasoline or GTX oil
It is normal for the oil pressure to drop some when warmed up.
It is just above the oil filter.
It is on the back of the block, about half way up from the oil pan.
Goes up and down if there are more particulates of oil
Worn oil pump or worn engine bearings.
bob is the best
