Check the pressure sending unit. If that is okay, you will need to use an actual oil pressure guage to determine that the pressure is okay. I believe it should be around 40 PSI, at a high idle (You can find actual specs in a repair manual). Some possible problems are worn oil pump, weak pressure relief valve, or something restricting oil flow. I hope this helps.

There is no relief valve on the oil pump.
The valve is on a housing near the oil filter
Normal pressure with HOT oil is 15 to 20 PSI at tick over and around 60 PSI when the engine is reved up
Note oil pressure can be as high as 90 psi with engine oil cold and engine reved up

While driving my chev 454 truck the oil pressure went to 0 psi


A leaking filter and oil pressure switch would cause the lack of oil pressure. Does the oil light work and does it go out now you have changed these parts. It only needs approx 8 psi to put the light out, the engine should run at approx 40 psi at 2000 rpm.

How do i tell if i have a bad oil pump or a bad oil sensor


If oil level in engine is at proper level, I wouild suspect oil pressure sending unit, does vehicle have an oil psi gauge on dash,,,if so what does it read. if oil psi reads well then it may be an oil level sensor. if you have access to a manual oil pressure gauge, you can remove the oil psi sensor and install manual gauge to get a true reading of what oil pressure is while running. if manual gauges shows low psi, then you may be looking at an oil pump.

Low presure oil


first thing check is the engine oil level.if oil level okay check oil pressure should be for the 4.2 engine oil pressure should be 12 psi @ 1200 rpm for the 5.3 oil pressure should be 18 psi @ 2000 rpm if oil pressure good problem in the oil pressure sending unit. if oil pressure is low problem faulty oil pump or worn crankshaft bearings if oil pressure low engine will have rod knock.make sure you are using correct oil viscosity if oil too thick you will have low oil pressure oil too thin you will loose oil pressure.

2.8l v6 in a s10 blazer. no head gasket problems thus far. wondering why my oil pressure gauge fluxuates? minor rpm change while oil pres guage does its thing why?


Oil pressure always changes with rpm.
At idle you should have around 10 psi, and it should max out at high rpm around 50 psi or so.
You not only can't have as much pressure at idle, but you don't need it either.

Why is oil gage reading 60? does this mean I need oil?


CHECK OIL PRESSURE FIRST.DEPENDS ON THE ENGINES SIZE JEEP OIL PRESSURE RANGES FROM 25 PSI TO 37 PSI.IF PRESSURE CHECKS OUT GOOD GAUGE COULD BE FAULTY.IF OIL PRESSURE IS STILL TOO HIGH.YOUR OIL TOO THICK.OIL RETURN HOLE STOPPED UP.OIL PUMP PRESSURE REGULATOR STUCK CLOSED.

Oil pressure gauge reads 80 psi with engine off and pegs running


That is probably a defective oil pressure gauge or a broken oil pressure sender, it reads 80 psi just because that is the maximum value allowed.

Pressure can be verified by reading it with a gauge tool.
If you really have pressure over 70 psi when engine is running then start replacing the oil filter, and check that the oil lines from pump are not obstructed, if there is nothing in there then replace oil pump.

If instead the gauge reads 80 with engine off, that is a defective pressure gauge.
