How to judge whether the engine is flooded?

There are the following methods:

1, check the oil.

The easiest way is to check whether the color of the oil is abnormal. If the oil turns milky white, there is water in the oil tank or engine.

2, check whether the pipeline water.

Check the air filter and the lower shell of the air filter one by one for obvious water inlet traces, and check the intake pipe and intake manifold for obvious water inlet traces.

Step 3 check the spark plug

Remove the spark plug of each cylinder and check whether it is wet. If it is wet, it means that the engine is flooded.

4. Check the engine cylinder wall for traces of carbon deposit.

When the engine works normally, the pistons of each cylinder reach the same top dead center position, and the top dead center position of the cylinder wall is clear. When the engine enters the water, because the water is difficult to compress, the piston cannot reach the original top dead center position, the piston motion stroke is shortened, and the top dead center position will move down obviously.

Maintenance method of transmitter water inlet:

1, if the engine is only mixed with water vapor from the air filter, it is not a big problem at this time. We only need simple treatment to clean the water vapor from the air filter, throttle and cylinder.

2. If there is a lot of water in the engine, it will not affect the normal driving, but the sound is relatively loud. It may be that there is a small amount of water in the oil and gasoline. We need to change the oil and clean the engine-related parts.

If there is a lot of water, it means that the engine has been flooded, not mixed with water, but the car has not started and the engine has not been damaged. We need to drain the water, clean it up, then reinstall it and change the oil with it, but the circuit system is not very safe.

Finally, there is another case where the engine can't run after it is started. At this time, the cylinder, connecting rod and piston of the engine have been deformed, so it can be concluded that the engine has been scrapped. We can only replace the new engine or simply scrap the car.
