How is the car leaking oil?

When the vehicle is in maintenance, the screw of the oil pan is not screwed tightly enough, which will make the sealing performance between the engine body and the oil pan worse, and oil leakage will also occur during driving. Pay attention to the oil pan spiral washer when repairing and maintaining the vehicle. Because the oil pan screw washer is a soft material, it will deform after being stressed, and there will be oil drain screws in the engine and gearbox, and the phenomenon of thread slipping is quite common. When the vehicle is repaired, it may cause oil leakage.

2. Oil seal or gasket aging:

The essence of oil seal is to seal oil. In use, the oil seal separates the lubricating part from the output part. With the extension of service time, the oil seal is damaged, resulting in oil leakage in the car. There are generally valve cover gasket, engine cylinder gasket and oil pan gasket on the engine, which will also lead to oil leakage after the vehicle ages.

3. The oil pan is damaged:

After the violent collision of vehicles, the air tightness of the oil pan will become worse, and even the bottom shell will break, resulting in a large area of oil leakage. Serious oil leakage from the oil pan will lead to poor lubrication of the engine, which needs to be solved in time to avoid abnormality in the use process, which will lead to vehicle failure and affect driving.

Attachment: Methods to prevent vehicle oil leakage:

1. Replace the failed oil seal in time;

The vehicle will shake when driving, resulting in the failure of the oil seal. With the extension of service time, the oil seal will also age and its elasticity will become worse. The owner of the vehicle needs to replace the oil seal in time after finding it invalid.

2, properly solve all kinds of tubing joint sealing:

The phenomenon of oil leakage in vehicles is mostly caused by insufficient sealing of joints. During routine disassembly, threads may slip or loosen. When maintaining the vehicle, we should also pay attention to check the pipeline joints to avoid oil leakage from the oil pipe joints and deal with the oil leakage from the joints in time.
