Check for coolant in the oil. remove the oil fill cap and look for a white milky substance. most likely engine damage has already occured because to have that low if oil pressure there is too much "clearance" between the bearings and the components they work with-(crankshaft,camshaft,connectiong rods). that vehicle came with dexacool coolant and it would shorten the life of the intake gaskets. they then would leak into the engine ruining the bearings over time. the skip can happen from lifters hydrolocked with the oil/coolant solution. take it to a reputable mechanic for an analysis......Good luck.......Scott

I have a dodge 1.8L. the oil ligh flashes when it running and my foot is on the accelerator, but comes off when it idles on its own.


It is not a big worry if the oil light comes on at low idle, but it should go off as soon as the revs rise a bit. I'd recommend

- change the oil AND FILTER with the correct grade, to the correct level.
- ask a mechanic to temprarily replace the oil pressure sender with an oil pressure gauge, and with the engine HOT, rev the engine up and down to see what pressure there is. You should have roughly 10 psi per 1000 RPM.

If the pressure is very low, ask the mechanic to check the oil pump and engine bearings. If you are not burning oil with lots of blue smoke from the exhaust, it is unlikely the bearings are worn.

Oil pressure warning light


The oil pressure light coming on at idle is not a big worry, so long as it goes out as soon as revs rise.. First step is to remove the oil pressure sender unit and screw in an oil pressure gauge. a mechanic can do this for you. This will tell you if the sender is faulty (common enough) or the oil pressure is low. A rule of thumb is to have about 10 psi per 1000 RPM in the normal rev range

If it is indeed low, possible causes are
- worn big end or main bearings (the car is old enough)
-faulty or weak over-pressure relief valve in oil pump
-worn or faulty oil pump
-blocked or sludged up oil passages
-blocked or sludged up oil pickup strainer mesh in sump

Some of these can be investigated by putting the car on a hoist and removing the sump

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

I'm having rough idle and smoke all of a sudden with my golf mk4 The oil warning lights up in dash. Oil level ok. Spark plugs not burning well. Replace spark plugs, changed oil filter, changed


Smoke is not a good sign. Running rough is not a good sign. Oil light not a good sign. You could have a combination of bad things, most likely expensive. Suggest professional help. Smoke can be bad rings or holed piston. Low oil pressure can be bad bearing or oil pump.

Oil light on after engine warm-up on idle


this means a mechanical gauge test is required to check actual pressure warm idling if low below 20 psi then the oil pressure pump relief is stuck open or engine bearing are worn

The oil light is on. I check the oil stick and its has the recommended amount. When you step on the gas, the light turns off. I noticed it smells burned oil; must be from an oil leak that probably drips...


The dash light indicates oil pressure. When idleing the pressure drops too low and and light comes on. As it revs up, pressure increases.. light goes off.
You should go here and read about low pressure. Too much to copy and paste here.

The small leak onto the exhaust maybe more than just a nuisance, it is a fire hazard. Potential to catch fire. Clean off the COLD header and front pipe with a non flamable solvent cleaner. Also the engine case around the area. You may find the source of the leak.

Problem with it is the oil light comes on when at a stop sign or at a red light but then goes off when you get going. But it's not leaking any oil, has had oil changes regularly


It's most likely one of two things: Your engine could be low enough on oil pressure when idling that the light is coming on for that exact reason or your oil pressure sensing switch could be faulty and misreading the actual oil pressure and erroneously turning on the light. The only real way to tell is to have someone remove the oil pressure sensing switch and temporarily install a mechanical test gauge in its place to check the actual oil pressure available. If it's low then there is an internal engine problem of some sort. If the pressure is about 10 psi or higher at an idle and 30 psi plus at 2500 rpm then your sender is at fault.

My jeep has the straight 6 and 260,000 miles. The oil pressure appears very low while at idle. However when I accelerate, it comes up. It is running fine, but I know oil pressure issues can be a potential...


well this is pretty normal for the mileage you have i suggest you switch to a heavier weight oil or what i do is add a quart of lucas oil treatment with each oil change that stuff is amazing i have seen it stop oil leaks and stop smoke from the tail pipe and it will raise your oil pressure 10 to 15 psi.

Engine misses on take off from stop.


check your fuel pressure, slightly low fuel pressure can cause this and it is possible that your other coil is breaking down under heat. also it could be as simple as your plug wires breaking down under heat
