Why does car engine oil contain water? What should I do if there is water in the car engine oil?

Water ingress into the engine oil of a car is a very troublesome problem and can damage the car's engine. If the engine oil is flooded, it is very complicated to deal with each time, and it must be dealt with in a timely manner, otherwise the engine may be directly scrapped. So why does water ingress into the engine oil of a car?

Why does car oil contain water?

1. During transportation, storage and use, engine oil will come into contact with air, and water in the air will enter the engine oil.

2. The cylinder gasket is damaged and cooling water enters the oil sump.

3. The cylinder liner water seal is damaged and cooling water enters the oil sump.

4. There are sand holes on the cylinder liner and cylinder head, and cooling water enters the oil sump.

Water in the engine oil will destroy lubrication, corrode parts, and cause harm to the engine. Therefore, you should pay attention to drainage at ordinary times, such as loosening the oil drain screw at the bottom of the oil, loosening the drain screw of the oil-water separator, and draining the water.

What to do if there is water in the car oil

First, determine the amount of water. If it is just emulsified, it may be a problem with the oil. There are actually a lot of counterfeit and inferior motor oils on the market. If the manufacturing process is not in place, a small amount of water can easily be mixed in. It cannot be distinguished by the naked eye, but when the high temperature of the engine is added, the oil and water mixture will emulsify.

If there is a lot of water, check the oil radiator, cylinder gasket and cylinder liner seal. Also check if there is any oil in the kettle. In this case, the engine is likely to have internal damage. It is not recommended to solve it yourself. Contact a professional maintenance person to help you solve it.

Can you still drive your car if there is water in the engine oil?

It is recommended not to drive again. If the vehicle stalls while passing through water, do not start it again.

It can also be turned on, but the air filter is flooded, the engine inhales air, and some of the water enters the intake duct to form water vapor, which is completely burned after mixing with gasoline, and has little effect on the engine.

A small amount of water enters the engine and mixes with the engine oil after entering the cylinder, the oil product becomes worse, the oil containing water will increase the wear of engine parts, and the noise and vibration of the engine drive of the vehicle may become louder.

The engine makes a sound when it starts and then stalls after a few seconds, and then fails to start after multiple starts. This is the most serious situation, because water cannot be compressed into the cylinder, and the engine is still working at high speed. The inability to compress water directly causes the valve and connecting rod top to bend, the piston to get stuck, the middle cylinder to be severely worn, and the crankshaft to bend. It is recommended to change the engine oil as soon as possible. Some models are designed on the blade or cover, and the amount of water caused by driving in water is too high to be compared.
