SOURCE: low,fluctuating oil pressure on 1993

If your vehicle has over 160000 miles on it and the low oil pressure is accompanied by engine noise.Chances are you have bearing clearence problems and or oil pump issues.The oil pan should be lowered for inspection.If there is no noise from the engine,install a manual aftermarket oil pressure gauge to make sure the original oil pressure gauge isnt faulty.Good Luck!!!!

SOURCE: Where is the oil pressure switch

Hello;
The switch is on the back of the block towards the firewall. Did the gage quit or? Hope this helps. Thanks;

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: 1991 chevy S10 blazer fluctuating oil pressure

I assume from the year it has high mileage. With mileage comes wear in these engine's bearings allowing oil pressure to drop because of the excess clearance between cam and bearings, also the crank and bearings. When the engine is hot and idling the oil is thinner and goes by the bearings quicker. If you have good oil pressure while driving, I'd leave it alone, maybe use a thicker oil or some lucas additive. My 89 does the same thing sometimes in the summer, but don't remember it doing it this summer. I use Mobil-1 and an AC Delco filter.

SOURCE: 2001 2500hd duramax idle surge. doesn't do it all

Well there are quite a few things that casue a "surge" in a common rail diesel. You will need to check injector flow rates (scanner only). Fuel pressure regulator for pulsing (scanner only). Supply side fuel system for air leaks (seeing if it is sucking air into the system).
My bet would be the injectors, because you say the rpms aren't going up and down, which is usally what happens when the regulator goes bad, and when you **** air into the supply they have an extended crank. Report back with your findings.

My s10 oil moves from 60 pass 80 on my gauge when idling and has trouble taking off Could it be my oil pump


Use a pressure test gauge to verify the pressure fluctuations at idle. It could be just a malfunctioning sender. If the pressure is, in fact, fluctuating then the pressure regulator is going bad. It is part of the pump so a new pump will solve the problem.

2 months ago my 04 avalanche oil pressure was fluctuating from 40 at take off to 10 when going steady 50 mph took to garage they said i needed a oil change and to add a luccas oil stabilizer in it and


The first thing any good technician would do about the oil pressure is remove the sending unit and hook up a mechanical test gage to see what the pressure is, GM oil pressure gages are famous for this very complaint, most likely the oil pressure sending unit is defective. As far as the other problems go it could be related.

Engine oil pressure high & fluctuate @ 90 to 100 psi when it cold. Engine oil pressure fluctuate at 50 to 60 pis when it warm. What is the problem on this issue?


The oil would thin out and could show lower pressure when its warmed. The sender for the gauge could also be bad.

Should the oil pressure gauge fluctuate with speed


The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!

Oil gauge fluctuates back and forth. sometimes


You'll need to determine if the oil pressure is actually changing, or if the sending unit or gauge is lying to you. Be certain the oil level is up to normal, then check the actual oil pressure with a test gauge. If the pressure varies (drops) at engine idle, perhaps your pressure bypass is defective, or perhaps the oil pump is worn. Testing with a known good pressure gauge should lead you in the right direction.

Fluctuating oil pressure on 92 Mercedes 300CE


Either the sending unit,(this unit is on the motor)is malfunctioning, or your engine oil pump may not be providing enough pressure.
This could be due to sticky oil pressure bypass valve,,worn out pump,,or worn engine main bearings.
If it is just a case of worn engine oil bearings,this is usually indicated by high oil pressure when cold,,but low oil pressure when hot,.i wouldn't worry to much, since most engines suffer from this same complaint and doesn't harm the engine any.

Fluctuation on the oil pressure gauge reading


The oil pressure sending unit is a sensor with an internal diaphragm, if the internal diaphragm is damaged , or the line to the diaphragm is blocked you can get this kind of fluctuation on the oil pressure gauge.

The oil pressure value must be read by installing a mechanical gauge near to the oil pressure switch and checking the pressure.

If pressure is ok, replace the sending unit. If there is a real pressure drop, check the oil pump.

If you still get fluctualtion after replacing the oil pressure sending unit, replace the oil pressure gauge.
