What should I do if the car chassis leaks oil?

Causes and solutions of oil leakage under the car: If it is only oil stains or oil stains, you can continue to use it and wait until the next maintenance. If it is an obvious oil drop, no matter where the oil leaks, it needs to be repaired in time and the seals or accessories should be replaced. You need to take a closer look. If there are obvious oil drops, it is recommended to go to the store for repair in time. During the warranty period, you can ask for the replacement of new faulty parts.

Oil leakage often occurs during the use of vehicles. Oil leakage not only directly affects the technical performance of vehicles, resulting in the waste of lubricating oil and fuel, consuming power, but also affects the cleanliness of vehicles and causes environmental pollution. Due to oil leakage, the lubricating oil in the machine is reduced, and the parts are poorly lubricated and insufficiently cooled, which will cause early damage to the parts and even leave hidden dangers of accidents. So, now let's analyze the main causes of automobile oil leakage and the hidden dangers of automobile oil leakage.

The main causes of oil leakage under the vehicle are:

1, products (accessories) with inferior quality, material or technology; There is something wrong with the structural design.

2. The assembly speed is improper, the mating surface is not clean, and the gasket is damaged, displaced or not installed according to the operating procedures.

3. Uneven tightening force of the fastening nut, broken thread or loose fall-off will lead to work failure.

4. The sealing material is worn, aged, deteriorated and deformed after long-term use.

5. Too much lubricating oil, too high oil level or wrong oil.

6, parts (side cover, thin-walled parts) joint surface deflection deformation, shell damage, so that the lubricating oil seepage.

7. After the exhaust plug and one-way valve are blocked, due to the difference of air pressure inside and outside the box shell, oil leakage often occurs at the place where the seal is not tight.
