How to repair the problem of Low Oil Pressure Warning Light?

If the oil level is low, add oil to the engine to bring the level up to the FULL mark on the dipstick. DO NOT overfill the crankcase. Use the type of oil viscosity specified in the vehicle owners manual.[url= http://www.xcardiag.com/wholesale/dyno-scanner-dynamometer-windows-powerful-automotive-scanner.html] Dyno-Scanner[/url] If the oil pump is bad (does not produce adequate pressure), the oil pump will have to be replaced. On most engines, the oil pump is located inside the oil pan on the bottom of the engine. The pan must be removed to replace the pump. This may require raising the engine and/or removing steering or suspension components that are in the way so the pan can be removed. On other engines, the oil pump is located inside the timing cover on the front of the engine. Disassembly required removing most of the components on the front of the engine to access the pump. If oil pressure is low because of worn engine bearings, the crankshaft bearings will have to be replaced. This usually requires overhauling or replacing the engine.

The oil pump can be changed without pulling the engine.

The impressive looking thing is the balance shaft assembly. These counter-rotating shafts balance out the inherent vibration of the engine. You can remove it, as long as you do not disrupt the gear placements relationship to each other. The balance assembly is set to a specific point.

SOURCE: low oil pressure - oil pump

well its been a while sense i have done one of thies, but i believe you have to unbolt both motor mounts and jack engine up as far as you can to get the pan off. if you can't get the pan off after you got engine jacked up as far as you can, you will have to unbolt front pump and take them both out at one time. and samething when you put it back together.if anything the picup tube is what will give you trouble, thats why you have to unbolt the pump.

Sounds like an ignition component failure check for proper resistance through primary and secondary ignition coil windings, refer to service repair manual for exact specs, also the ignitor magnetic pick up may be not up to snuff, the only other ignition component to replace or check is the ignition module and/or plug wires themselves, sometimes when extreme demand is put on the ignition system the plug wires must be high quality and completely isolated from one another. Spark plug wires when routing cannot come in contact with one another in the slightest proximity.

SOURCE: Dic warning "engine Oil Low - Check Level" but the

you may have a sensor bad in the crankcase that detects oil level.
I would disregard as long as the oil is changed regularly, and you have no pressure problems and the level on the dipstick is within the cross hatches or between the low and high range.

Why would the oil light stay on?


That depends on the type of oil warning light being displayed. There are 2 types of warning lights

1. Low oil pressure light which all cars have
2. low oil level light which some cars have.

Low OIL PRESSURE warning means the oil pressure is below minimum and when this happens there will be insufficient lubrication of many engine parts because sufficient oil cannot get to all parts of the engine it is required to lubricate. Until the cause is identified and rectified the warning light will remain. If you run your engine with low oil pressure you will cause expensive damage to internal engine components.

Low OIL LEVEL warning means the oil in the sump has dropped to a dangerously low level (which may be due to an oil leak or abnormal oil consumption by the engine.) This warning means the oil level needs to be topped up and the warning will stay displayed until you top up the oil. Running the engine with low oil will cause expensive engine damage.
Since it is a 2 minute job, Oil levels should be checked fortnightly as a minimum, together with radiator coolant and power steering fluid levels, if you run the car most days each week as most people do.

It is possible for a warning light to remain displayed when the cause has been dealt with because there is a problem with the sender unit. However it needs to be established with alternative checks that the problem has been fixed before investigating if there is a problem with the warning light itself.

Oil pressure low is on,and it say stop engine can I drive it if I put oil in it


If the oil PRESSURE is low, AND you have plenty of oil in the engine, DO NOT drive it.

If the oil level is low, add oil to the "full" mark on the dipstick. Start the engine, and see if the light goes off. If the light goes off, you can drive it.

No oil pressure when idling/stoplight


What is the mileage on the vehicle? What type of oil are you using, synthetic or conventional oil? Older engines that have a fair amount of wear (loose essentially). I had this problem on two different vehicles. If the oil is not near time to be changed (fairly clean oil) I would get a new oil filter and prepare it by filling it with STP oil treatment. This is thick stuff and will thicken your oil. Remove the old oil filter and put the new one on. Start the engine and let it idle for a minute then shut it off. Check the oil level and add more STP to bring it back up to the full mark. Start it and check the oil pressure. If this helps bring the pressure up then I'd say its time to go to a thicker oil. I switched to 0w40 synthetic after trying 5w30 (5w30 is recommended by mfr.) and have had no more trouble. The thing is that synthetic oil tends to thin more at temperature than conventional oil does.

Light


This is the "Low Oil Pressure Warning" light. It is RED for a reason! When this light (or any RED warning light for that matter) comes on, pull over and shut the engine OFF at once. Allowing the engine to run with insufficient oil pressure can cause a catastrophic failure in mere seconds. Such a failure can cost thousands of dollars to repair.
This warning is most often the result of a very low oil level as indicated when checking on the oil dipstick. The engine oil level should be maintained as close to the "full" mark as possible - without exceeding it. Oil should never be allowed to drop below the "low" mark on the dipstick. If the oil level is shown to be between full and low, the light is probably coming on as a result of a faulty oil pump (the oil level should be checked with the vehicle parked on level ground, with the engine OFF). A faulty oil pump is unable to pump the oil with enough pressure to reach all the moving parts of the engine that require lubrication. Without proper lubrication, connected moving parts heat up, expand and seize. Moving parts are expected to move - not be prevented from moving.
If your engine shut down, it may be the result of some of the internal parts seizing. Hopefully, this is not the case. Check the oil level and top off as needed to bring the level up and attempt to start the engine and have the vehicle checked by a trusted mechanic.
Good luck!

How can i fix the oil pump


see this tips and fix it. God bless you
The oil pump supplies oil to lubricate your engine. If the oil pump is worn or is not turning, the engine will suffer a loss of oil pressure, which may result in engine damage or engine failure.
The first sign of trouble may be a low oil pressure warning light, a drop in the normal reading on you oil pressure gauge (if your car has one), or the appearance of ticking or clattering sounds from your engine.
As a rule, most engines only need about 10 PSI of oil pressure for every 1,000 RPM of engine speed. Oil pressure will read higher than normal when a cold engine is first started because the oil is thick. Oil pressure will gradually drop as the engine warms up and the oil thins out. So normal oil pressure on a warm engine cruising down the highway is typically 30 PSI up to 45 PSI.
SYMPTOMS OF OIL PUMP TROUBLE
The first thing you should do if any of these symptoms occur is to stop your car, turn off the engine, let it sit for a few minutes, then check the oil level on the dipstick. If the oil level is at or below the ADD line, add a quart of oil to bring the level back up to the full mark. Add as much oil as is needed to raise the level to the full mark. Then restart the engine. If the warning light remains on, or the oil pressure reading does not climb back up to its normal range, or the engine noise does not go away, you may have a bad oil pump.
The other possibilities include a bad oil pressure sending unit, or a problem with the oil pressure warning light circuit or oil pressure gauge.
OIL PRESSURE SENDING UNIT
If the engine is NOT making any unusual noises and seems to be running normally, and the oil level on the dipstick is FULL, but you are still getting a low oil pressure warning light or low gauge reading, the fault could be a bad oil pressure sending unit.
The oil pressure sending unit is mounted on the engine block. On some applications, there is a spring-loaded pressure-sensitive diaphragm with a switch inside the sending unit. This switch completes the circuit to the low oil pressure warning light if oil pressure drops below a certain threshold. The unit may stop working if the diaphragm inside fails, if the switch is stuck, if the small hole that allows oil to enter the sending unit becomes plugged, if there is a loose, corroded or broken wiring connector at the sending unit, or there is a fault in the wiring circuit between the sending unit and warming light.
On vehicles that have an oil pressure gauge (electronic, not mechanical), the oil pressure sending unit has a small rheostat inside that sends a variable voltage signal to the oil pressure gauge when the diaphragm moves. A worn spot on the rheostat or any of the other problems just described for the simple pressure-type oil pressure switches can cause a problem.
FORD'S FAKE OIL PRESSURE GAUGE
On many Ford vehicles that were built from 1980 through the 1990s, the oil pressure sending unit has two switches, a low pressure and a high pressure. These vehicles also have an oil pressure gauge, but the reading on the gauge is not a true indication of real oil pressure. As long as the pressure to the sending unit is between high and low, the gauge will read normal. If oil pressure drops and trips the low pressure switch, the dash gauge will now read low. Or, if oil pressure goes up and trips the high switch inside the sending unit, the dash gauge will read high. Consequently, don't rely on the oil pressure gauge for an accurate reading in these vehicles. It is only a gross indication if the oil pressure is low, normal or high.
OIL GAUGE PROBLEMS
If the engine is NOT making any unusual noises and seems to be running normally, the oil level on the dipstick is FULL, and you have replaced the oil pressure sending unit but are still getting a low oil pressure reading on the dash gauge, the fault could be in the wiring circuit between the sending unit and gauge, or the gauge itself might be bad.
Check the wiring connections on both ends as well as wiring continuity between the sending unit and gauge. If no wiring faults are found, hook up a pressure gauge directly to the oil pressure port on the engine and check oil pressure with the engine running. If the engine-mounted gauge shows normal oil pressure but the dash gauge is reading low, the problem is a bad dash gauge.
On the other hand, if the engine-mounted pressure gauge reads low and you have done all of the above, chances are the oil pump is worn, or it is not picking up enough oil because of a restriction or blockage in the pickup screen in the bottom of the crankcase.
OIL PUMP PICKUP PROBLEMS
The pickup tube has a screen on the end to prevent large chunks of anything bad that ends up in the crankcase from being sucked into the pump. But we are talking BIG chunks of debris, not normal wear particles or carbon or dust or other microscopic-sized abrasive particles that can cause pump wear over time.

Ticking sound with accelerating and coolant running out everyday... any solution?? thanks.


Hi there:


A clicking or tapping noise that gets louder when you rev the engine is probably "tappet" or upper valvetrain noise caused by one of several things: low oil pressure, excessive valve lash, or worn or damaged parts.

First, check the engine dipstick to see if the oil level is low. If low, add oil to bring it back up to the full mark. Is the engine still noisy? Check your oil pressure. A low gauge reading (or oil warning light) would indicate a serious internal engine problem that is preventing normal oil pressure from reaching the upper valvetrain components. The cause might be a worn or damaged oil pump, a clogged oil pump pickup screen or a plugged up oil filter. Using too thick a viscosity of motor oil during cold weather can also slow down the flow of oil to the upper valvetrain, causing noise and wear.






Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Oil warning light flashing mean?


Normally, if you get a oil warning light signal (flashing) could be a few things related to it. Number one, you are low on oil. Check your oil level and make sure it is at full level. Number two, is possibly oil filter is dirty, ( time for service,oil change) or problem with oil pump or oil pump pressure. BUT I would first start with checking oil level and then maybe a oil change.

Low oil light comes on , is it low oil pressure or low oil level


it is a combanation of both low oil level =low oil pressure check your oil level and make sure it is on the full mark and drive it to see how pressure is it could also be the oil pressure sending unit good luck

If your oil pressure light comes on
Don't ignore it. An oil pressure warning light (or low gauge reading) means one of two things: either your engine has dangerously low oil pressure (for a variety of reasons which we'll get to in a minute), or the oil pressure sending unit that triggers the warning light (or operates your gauge) has failed.
The question here is whether you have a serious problem or a minor one.
First, do not keep driving if the oil warning light is on or your oil pressure gauge has dropped. Stop the engine, let it sit for a few minutes, then check the oil level.
Is the level low? If the oil level is down more than two quarts or no oil is showing on the dipstick, adding oil to bring the level back up to the full mark may be all that's necessary to make the light go out. Just keep your fingers crossed that you haven't damaged the engine from running it too low on oil. If you hear rapping or knocking noises the engine starts, you're too late. The damage is done and now you're stuck with the consequences.
Note: On some late model vehicles, the warning light will come on (or a message will appear) if a sensor in the oil pan detects a low oil level. The light is supposed to come on before the level gets low enough to cause any damage.
If your oil level was low, it means your engine is either leaking oil or burning it. Leaks can be fixed by finding and replacing leaky gaskets and seals. Sometimes the oil filter will leak if it isn't installed or tightened properly. But an oil burning problem means the valve guides, rings and/or cylinders are worn or damaged and more costly repairs are needed.
If the dipstick shows a full oil level, then low oil obviously isn't your problem. The oil pressure may be low because of a worn or broken oil pump, a plugged oil pickup screen in the engine's crankcase, possibly a plugged oil filter or excessive bearing wear. Or, the oil pressure may be fine but the oil pressure sending unit has failed. Further diagnosis will be required to determine what's wrong.
Should you attempt to drive your vehicle home or to a service facility?
It's risky. If the problem came on suddenly, your engine does not have a lot of miles on it (less than 60,000) and you noticed no unusual noises (no valvetrain clattering or engine knocking), there's a good chance that all that's wrong is the sending unit. But, there's no way to know for sure without actually checking the engine's oil pressure with a gauge, or replacing the sending unit to see if a new unit makes the light go out. If the problem is only the sending unit, your engine still has oil pressure and you can continue to drive it until the sending unit can be replaced. But, if you're wrong you risk ruining your engine.
If you think you might have a low oil pressure or oil delivery problem because of a bad oil pump or one of the other problems we mentioned, do not drive your vehicle. Doing so only increases the probability of further engine damage. Have the vehicle towed to a service facility for repairs.
