Engine oil intake can be said to be a common vehicle failure problem, enough experienced drivers can directly from the oil color, odor, viscosity and turbidity to determine the quality of the vehicle engine oil. Today, we're going to talk about how to judge the water in your engine.

The oil after water, if not timely treatment will cause more serious consequences, such as stroke cylinder, lava and other more serious fault, will make the engine be scrapped, therefore, keep the water away from oil is a must always pay attention to the problem.

Since the engine oil intake is a common fault in the use of internal combustion engine, then how should we judge whether the oil is water? How should we go to find the root cause of oil intake?

How to determine oil intake

1, observe the oil dipstick

If the oil in the engine oil of the engine is heavy, the oil surface of the engine will rise in Baotou. At this point, we can use the ruler to judge. Once the oil in the water content is too high, then the level of lubricating oil will exceed the range of dipstick tagging.

2. Check engine coolant

Check whether the engine coolant contains oil in the engine parts of Baotou North heavy truck. If some parts of the engine are damaged, the engine coolant will enter the lubrication system, and the oil will be found in the coolant at this time.

3. Observe the color and appearance of the engine oil

If you look at the appearance of the oil, you can easily judge whether it contains water. Water free oil presents a translucent oily color, while water containing lubricants appear opaque brown or khaki.

If the oil contains moisture, then the engine runs for a period of time, the oil will be milky white, and accompanied by foam. This is due to the high temperature in the engine, the oil and coolant chemical reaction, oil will be emulsified into emulsion.

How to deal with the oil intake?

The oil inlet light will lead Baotou beiben parts of the engine temperature is too high, or it will lead to the cylinder, holding tile and other faults, more will lead to serious engine scrap. So what are the principles that lead to these failures?

In general, the water content in the oil is less than 0.03%, if the water content is more than 0.1%, the additives in lubricating oil (such as antioxidants, detergent, dispersant, etc.) will react with water and then fail, and the performance of the oil will decline.

In the engine internal high temperature, the oil will react with coolant, chemical oil will be emulsified, oil lubrication will be reduced a lot.

When the oxidation resistance of the engine oil drops, the organic acid produced by the oxidation of the oil will react with water to produce inorganic acid, which will cause corrosion to the engine parts, causing the parts to rust or damage.

The main reason of oil water inflow

1, oil radiator damage led to oil into water

The oil radiator is damaged, the radiator pipe is broken, the water outside the radiator will penetrate into the oil radiator, which leads to oil water.

2, cylinder seal ring damage, leading to oil into water

The wet cylinder liner contacts the cooling water directly, and the sealing ring at the lower part of the cylinder liner can effectively prevent the leakage of oil and cooling water. In use, the sealing ring bears a certain pressure, sometimes the water quality of cooling water is bad, it will cause corrosion. After the engine running for a long time, the sealing ring is easy to fail.

Cylinder seal ring damage is one of the main reasons for oil intake, so, in checking the cause of the water into the oil, must remember to check whether the cylinder liner is intact.

3, cracks in the cylinder liner easily lead to oil into water

When the heating cylinder direct contact with cooling water, it is easy to produce cracks, cracks will occur once, cooling water directly into the cylinder and the cylinder into the oil pan, this will make the oil turned white, and white oil will cause the engine burning bad, white smoke caused problems.

4, cylinder gasket damage led to oil intake

The function of the engine cylinder gasket is to seal the water channel and the oil channel corresponding to each cylinder and each cylinder, so as to avoid the oil water inflow. If the cylinder gasket is damaged and the water circulation is fast, the water in the channel will flow into the oil channel and cause the oil to enter.

Cylinder gasket damage is one of the important reasons for oil intake, after each machine is removed, try to use a new cylinder pad, so as to avoid leakage of the cylinder liner leakage caused by oil, resulting in engine damage.
