SOURCE: oil pressure guage dropping

Sounds like the sensor is failing.Have oil pressure checked with a mechanical gage to confirm. A new sensor or wiring repair is allot cheaper then a new engine!!

SOURCE: I have a '93 chevy silverado 1/2 ton with oil pressure problems

Sounds like the engine bearings (crankshaft) are worn. Try using a heavyer grade of oil, unless you want to rebuild the engine.

SOURCE: Fluctuating oil pressure gauge.

Two quarts is about half the capacity. The pump was probably starved of lubrication and is failing.

If that's not expensive enough, you may now have a problem with a damaged engine. You may want to just put that money into a new vehicle.

I don't think the car would have enough power in its present condition to get high enough to reach a cliff, and driving it into a lake would not be environmentally sound. Besides, the fine would not be worth it.

The cheapest and easiest maintainance that anyone can do on a car to avoid expensive repairs is still checking the oil ever 1000 miles (filling if necessary!) and changing it every 3000.

SOURCE: THE OIL PRESSURE GAUGE DROPS TO ZERO AND LIGHTS ON

poor oil circulation may need either more oil or a new oil pump, any other symptoms?

It could just be the pressure sensor, as this is cheaper get it looked at first.

Hope this helps

Dan

SOURCE: oil pressure at 0 on 2005 trailblazer

It sure sounds like the oil sending unit is at fault,now sometimes,not always,the oil sending unit will seep oil or leak oil if they go bad,but like I said,not always,change the unit,and the oil and filter just for precaution.

I have a 01dodge RAM 1500 and the oil gauge keeps going from 40 to 0 and the check gauges light keeps coming on but I checked the oil and it's fine, what could be the reason for this


1. You need to have an independent oil pressure gauge hooked up to the engine to check the oil pressures at various RPMs and to verify the 40 to zero drop. This will eliminate any issue with the pressure gauge or the sending unit.

2. The oil pressure variation can be caused by an intermittent blockage in the oil pick up or an intermittent sticking oil pressure relief valve. I would possibly suspect the latter if you are getting good pressure and it is intermittently dropping to zero and going back up again..
If you or previous owners have not maintained the engine with frequent oil changes you will get a sludge build up problem in the engine and this will be evident by just dropping the engine sump.

3. If you have had a check engine light warning then you need to have the vehicle scanned to see what fault codes have been generated by the computer. There will be some related to the intermittent loss of oil pressure but there may be others also..

4. You need to have the oil pressure problem checked out immediately. Running the engine when you constantly lose oil pressure intermittently will definitely cause engine damage due to a loss of both lubrication and oil cooling to critical components.

Check engine oil pressure light coming on and causing engine to die. After 5 minutes, no light and no engine trouble.


Yes I would say the oil pressure switch is faulty. The oil pressure gauge uses a different sensor, so if the gauge did not drop but the warning light came on, I would have the warning light switch checked. If the warning light comes on, the fuel pump will stop getting power and you will lose fuel pressure too.

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.

My check gauges light is on, oil hands goes over to zero, moves up, light goes off, when it drops back to zero, gauge light comes back on.


Well the warning light is supposed to come on if any of the gauges display a dangerous condition, such as no oil pressure.
You may have a faulty sending unit for the gauge, or a wiring problem, or the engine may actually be loosing oil pressure when the gauge drops.
You could replace the sending unit as a test, or have someone check the oil pressure with a mechanical gauge.

Oil pressure drop with engine getting hot


You'll want to remove the electrical oil pressure gauge and check the oil pressure with a manual gauge to verify low oil pressure. If the oil pressure tests good with a manual gauge, then you either have a faulty oil pressure sender, or gauge in the dash (I rarely see faulty gauges). If the pressure is still low, suspect worn crankshaft bearings. There is also a possiblity that the screen to the oil pump is clogged. This can be visually checked by removing the oil pan and cleaned.

2004 Doge Ram 2500 5.7 Hemi 190K mile had oil pressure gauge drop to ZERO and check gauges light come on and engine shut down.. Check oil 1 guart low, add oil. let cool. crank up, good gauges drove home 45...


If the valve lifters are quiet you most likely have oil pressure even with gauge showing "0".Sounds like the oil pressure switch going bad.I would try that first.

Oil gauge drops all the way down and check gauge light comes on


Could be the oil pressure sender has gone bad or worse case scenario the oil pump has worn out. Check the oil presssure sender first, if it is leaking around it then that is the cause, if not then you may be looking at an oil pump. Just had a 03 ram 2500 doing the same thing and it was the sender, but that was a hemi and it had 230000 miles and a month later had to replace the oil pump for same issue.

Come to stop 99 Ram oil pressure drops to 0 check gauges light.


Change the oil! The 318Cu in V8 (5.2 liter) engine has a problem with sludge build up on the oil pump pickup tube screen. This engine requires oil changes at or before 3500 miles with a high detergent oil.
