1. Screws not tightened or slipping:

When the vehicle is being repaired, the screws of the oil pan are not tight enough, the sealing between the engine body and the oil pan will become poor, and oil leakage will also occur during driving. When the vehicle is being repaired and maintained, attention should be paid to the screw washers of the oil pan. As the screw washers of the oil pan are soft, they will deform under force. There are drain screws in the engine and gearbox, and the phenomenon of sliding wires is relatively common, The coiled belt may occur during vehicle maintenance, resulting in oil leakage.

2. Oil seal or gasket aging:

The essence of oil seal is to seal oil. During 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 of the vehicle. On the engine, there are generally valve cover gaskets, engine cylinder gaskets and oil pan gaskets. After aging, it will also lead to oil leakage of the vehicle.

3. The oil pan is damaged:

After a severe collision occurs, the air tightness of the oil pan will become poor, and even the oil pan will break, leading to a large area of oil leakage. Serious oil pan leakage will lead to poor lubrication of the engine, which needs to be resolved in time to avoid abnormalities 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:

When the vehicle is running, it will shake, which will lead to the failure of the oil seal. With the extension of the service time, the oil seal will also show signs of aging, and its elasticity will become poor. When the owner finds (check the transaction price | participation | preferential policies) that the oil seal is invalid, he needs to replace it in time.

2. Properly solve the sealing of various oil pipe joints:

When the vehicle leaks oil, many of them are caused by the insufficient sealing of the joint. During the daily disassembly process, the thread may slip or become loose. During the maintenance of the vehicle, attention should also be paid to the inspection of the pipeline interface to avoid oil leakage at the oil pipe interface, and any oil leakage at the interface should be handled in a timely manner.
