1. What is the harm of engine oil leakage.

The main harm is the loss of oil, causing waste, polluting the environment, and in serious cases, it may lead to insufficient oil, which may lead to engine damage, and may even cause the vehicle to spontaneously ignite. The damage to the engine is not caused by oil leakage, but because the oil pressure is insufficient after the leakage, so pay close attention to the oil level.

2. Strictly distinguish it from engine oil leakage!

First of all, engine oil leakage and engine oil leakage are two concepts: engine oil leakage is a kind of failure phenomenon; engine oil has a strong penetration ability, and engine oil leakage occurs with the use of the engine. Under normal circumstances, it will penetrate from the oil seal. One point, this is a general phenomenon, it is not a malfunction. Oil seepage is mainly reflected in a small amount of oil traces visible at the engine seal, the oil does not decrease rapidly, and no obvious oil traces are found on the engine guard or on the ground.

3. Therefore, when the maintenance station judges the oil leakage, it should first confirm which part and which part the oil leaks.

You can't just think it's a seal problem subjectively. You should find the real cause and take countermeasures according to the oil stain. Otherwise, the problem may not be solved by replacing the wrong parts.
