What to do if your oil pressure gauge goes bad?
The gauges are very good and almost never go bad but it could happen but not likely. Start with the wire connection and make sure it is good and clean. WD-40 spray will help in the cleaning of it along with a good clean paper towel. Try that first. 28 people found this helpful.
What should oil pressure be after changing oil sending unit?
OIl pressure still drops after changing oil sending unit? When truck is first started, oil pressure is normal, around 40 psi. When engine temp starts up, oil pressure slowly falls until “Stop Engine – Low Oil Pressure” warning comes on. Switch truck off a few second, maybe 20-30, restart truck and back to 40. And on and on.
What should I do if my oil pressure drops?
If the vehicle starts making a tapping or clunking noise when the oil pressure drops …TURN OFF THE ENGINE…!! You probably don’t have any oil going to your engine and it will seize up (lock down). You have a bad oil pump. 20 people found this helpful. My 4.3L engine in my 1998 s10 has 150,000 miles.
Why does my oil pressure drop to zero?
Just went through this with a 2002 sierra 5.3, Pressure would randomly drop to zero and if I did not kill the engine fast ehough I would get a bad lifter tap so it was definitely not a bad sensor/sending unit. Even though the truck had extremely low mileage and oil changes were routinely done sediment had built up in the engine.
What should I do if my oil pressure gauge is high?
Please try again later. If your instrument panel ( dash ) is telling you that you have really high oil pressure, your gauge is actually broke. It is 99% of the time a bad ground that is on the fire wall behind the engine. All you need to do is check the oil level on your dipstick. Loading…

What to do if your oil pressure is low?
Check engine light came on the low oil pressure light and DIC alarming to shut engine down. Shut engine down and restarted, oil pressure went back up to 40 and continued to drive until it happened again. I dumped a can of seafoam in the crankcase and ran it through for a while, changed the oil and filter and never had a problem since.
