Oil pressure drops and truck shuts off


I have to ask if you are sure the oil pressure drops first, or the engine stops first. The engine would stop if the oil pressure dropped below 5psi but only because the fuel pump would shut off. And it should start back up if that were the reason.
If something such as a relay or the ignition module is getting hot and killing the engine, it might have to cool down before it restarts. And the engine would stop then the oil pressure would drop to zero.

Oil Pressure Drops


Did the mechanic drive the truck with a mechanical gauge to check the pressure ? The engine bearings or oil pump could be worn enough to allow pressure to drop at idle after it warms up.

2002 4.8l gmc yukon oil pressure problem


My suggestion would be to check it with a mechanical gauge.
You would need to use a Tee fitting to use the sensor to have fuel pressure.
If the mechanical gauge shows steady pressure at idle, it could be a problem in the wiring or the instrument cluster.

Oil gauge goes to 80psi while I'm driving 70mph on highway, drops when I slow down. Why?


They are designed to change as the motor changes speed. If you have 80 lbs. of oil pressure than you have very good oil pressure in your engine. If it gets higher than 80, I would talk to service dept. at your local dealer.

You need to have the oil pressure checked with a manual oil pressure gauge you may have a bad sending unit. If the you oil pressure is the same with the manual gauge then you have a oil pressure problem.

1993 GMC Sierra C1500 5.7 just recently started having the oil pressure drop. We think it may the oil pressure gauge where would that be at. We don't want to change the pump if changing the gauge will fix...


Most likely the Gage is not the problem these rarely go out. If the pressure is only dropping then the oil pump is getting weaker or is filling with sludge. Try running the engine with an oil additive such as marvel mystery oil or sea-foam. Then after the additive has circulated through the engine for a few heat ups and cool downs you can change your oil. the pressure should change almost immediately. If it doesn't then check the oil pressure switch. You can look on the side of the block and there will be a small piece shaped like a pencil with a wire coming from it. This piece is the oil pressure switch. Hope this helps. Please rate me if you think this helped. Good luck.

That's normal in most cases, depending how low it goes. 40 psi approx when driving, 20 psi approx when idling ?

1997 Eagle Talon TSI AWD oil pressure goes from zero to normal and back


Te 1st thing to do is replace the oil pressure guage sending unit, most times that is the problem, if press remains low use a mechanical test guage to verify what the oil pressure is, hook this tester up at the port the sending unit is screwed into.
