Incorrect engine oil pressure - causes, symptoms, consequences

Engine oil plays a very important role in ensuring proper lubrication of all parts of the engine. This is why it is so important that he has the correct blood pressure. If the parameters do not match, the ignition control lamp comes on. Where to look for the reasons for this state of affairs? What are the symptoms and what do they lead to? Check!

What will you learn from this post?

• What are the causes of low engine oil pressure?
• What are the causes of high engine oil pressure?
• How does oil pressure affect oil pressure?

Shortly speaking

Incorrect engine oil pressure has very serious consequences for the engine. Components may jam or device may leak. An engine overhaul is very expensive, so if you notice that the pressure light is still on, stop immediately. Check engine oil level. In addition, check the condition of the oil pressure sensor and the connecting cable between the signaling device and the sensor. The most serious defect is the wear of the crankshaft bearings - in this case, the engine cannot be replaced or repaired.

This needs to be checked - the engine oil level.

Some drivers no longer hear about engine oil and the important role it plays in a car. Nevertheless, it should be understood that without it, you can practically forget about comfortable driving i good engine condition... Worth taking care of correct oil levelsince this problem is directly related with his pressure.

When the car starts the light on the cab automatically comes onwhat informs incorrect oil pressure. We don't have to worry about it pressure increases with engine speed. However, if it does not reach him in a few seconds values ​​35 kPa, the light will not go out, so please send us information about the problem. What then is to be done? Immediately stop the car Oraz turn off the engineand then think about where to look for the cause.

The first thing you should do is check the engine oil level. You may find that this is it too little or too much. If the engine suffers from lack of lubrication, fill in the gaps as soon as possible - the indicator does light up in a pinch, signaling yes Low oil level, what can happen at any moment capture of work items. However, too high a liquid level is no less dangerous - its consequences can be block opening because of the impossibility excess oil is transported through the overflow valve to the sump.

Where can I find the cause of low oil pressure?

Yes, as we mentioned earlier, too low oil pressure may be caused by an incorrect oil level. However, if everything is in order and there is enough fluid in the engine, look elsewhere for the problem.

First check that oil pressure sensor is working properly... This can be done in any workshop. It is known that if this driver has been corrupted, reading will always give incorrect information. The problem can also be caused by damaged wire connecting the siren i sensor which leads to the fact that messages are not able to reach the driver or their content does not correspond to reality. In addition, as a result, the warning lamp may come on. the oil intake to the pump is clogged, which connects with oil pan, as well as the bypass valve is blocked, remaining in the open position at all times.

However, the biggest failure is worn bearings on the crankshaft... How do you recognize the problem? It signals it an indicator light that comes on when the engine is warm and running at low revs. So what? You should definitely measure pressure with a manometer, and if the fears are confirmed, then it will be necessary overhaul of the engine.

High engine oil pressure - be sure to check!

High blood pressure is a much less common problem than low blood pressure, but it can also happen. This error is the most commonj in diesel engines, they have particulate filter. Then, as a result, nUnsuccessful burnout of soot from the filter leads to the ingress of an increased amount of fuel into the combustion chamber.which then flows into oil pan increasing the oil level, and hence the pressure.

The reason for the high oil pressure may be the same– Incorrectly made replacement of a liquid in the engine. If the mechanic guessed the power of the system i the amount of liquid specified by the manufacturer is poured inside, and there was still an old liquid that she did not manage to merge during the exchangehe naturally created himself excess that has raised the pressure and made the indicator light constantly.

If you notice that the low engine oil pressure indicator is still on, natychmiast answer... Maybe it meansDangerous for the engine Incorrect oil level Or other serious malfunction. Don't underestimate these symptoms The engine is the heart of the car. Are you looking for a good quality motor oil? Check out our offer in the Nocar online store.
