How to judge whether the engine is healthy?

The engine of the car is broken, not to mention the driver of our novice Xiaobai, and even the maintenance master can hardly make a judgment. This is not an alarmist, the reason is very simple, because the engine is completely sealed and there are many and complicated parts. It's hard to say what happened inside. When you obviously feel that something is wrong, it is already a big problem.

In this issue, I will tell you how to observe the engine daily. There is nothing we can do about the engine, but we can only let it go. You can observe and check the oil cover at ordinary times. If the following phenomena occur, it means that there is something wrong with the engine and maintenance inspection is needed.

In the first case, if there is a lot of yellow substance on the oil cover, it means there is a problem. The oil cover of a normal car is black, if the color of the oil cover is obviously wrong. Don't panic yet. Another situation is that the maintenance master added too much oil to you during the last maintenance, and the oil label was incorrect, or the oil inside was not cleaned before the last oil change, resulting in the wrong color of the oil cover.

So what do we usually do?

If there is only a little more oil, just go to the repair shop to deal with it. If there is obviously too much oil, you should check the cause as soon as possible to see what is wrong with the engine.

The second situation is that the deposit on the oil cover is a bit like milk. Once something of this color appears, it means that the oil has been emulsified and deteriorated. That did some damage to the car. Need to go to the repair shop immediately, clean the engine, thoroughly clean the engine, and then change the oil.

What is the reason for oil emulsification?

There are two reasons: on the one hand, the ambient temperature is too low. Emulsifying phenomenon is easy to appear when the oil is kept in a low temperature environment for a long time. On the other hand, the engine has been flooded before. When oil contains too much water, it will deteriorate and fail. Of course, poor engine ventilation is also one of the reasons for oil emulsification. This is a design flaw, which is not common.

The third situation is that there is a lot of black sludge on the oil cover. This phenomenon shows that the problem of engine carbon deposition is serious, and there will be an increase in fuel consumption, insufficient power and obvious increase in noise. In this case, your engine has been seriously damaged and needs to be repaired as soon as possible.

In this issue, I will give you some knowledge about checking the oil cover to judge whether the engine is healthy or not. Because the engine is in a sealed state, it is difficult for us to find its problems. Once it feels serious, it is often irreversible. Therefore, it is necessary to pay more attention to observation in order to keep your car in good condition.
