FAQ
Why does the car crankshaft oil seal leak oil?
1. The supplier you cooperate with replaces expensive non-petroleum-based lubricants with cheap oil, so your car crankshaft oil seal will loosen and fall off after a short time of use.
2. The installation surface of the crankshaft oil seal is not suitable, and the manufacturer's technology is not good enough. After the engine is used for a period of time, the oil seal lip is deformed, and the entire oil seal will be deformed.
3. The engine has been used for too long, and the rear oil seal is naturally aged.
