1, the possible causes of automobile oil leakage are aging, damage and failure of engine bottom seal or stone scraping the engine bottom. Oil leakage will lead to less oil, insufficient lubrication, accelerated internal wear of the engine, reduced service life of the engine, and may seriously damage and burn the engine.
2. With the passage of time and the constant alternation of cold and hot, the automobile sealing strip will gradually harden and lose its elasticity, and may break seriously, leading to poor sealing and oil leakage.
Second, the harm of oil leakage:
The amount of engine oil is closely related to the performance of the car. Too little engine oil can easily burn the Vara cylinder, and in severe cases, it will cause the crankshaft to break and damage the cylinder block. Too much oil will have an impact on the power of the car. Too much oil will easily lead to the burning of oil string and oil, so the oil should be added according to the standard.
Extended data:
Measures to prevent vehicle oil leakage:
1, pay attention to the role of the gasket. Gaskets between parts where cars are parked play the role of leakage prevention and sealing. If the materials, production quality and installation do not meet the technical specifications, it will not play a role in sealing and leakage prevention, and even accidents will occur.
2. Replace many parts of the faulty oil seal vehicle immediately, and the oil will be thrown away due to improper installation, misalignment and deviation of the journal and the oil seal cutting edge. Some oil seals will lose their elasticity due to rubber aging if they are used for too long. If leakage is found, it should be updated immediately.
3. Prevent the one-way valve and exhaust valve from being blocked, which will cause the temperature in the tank shell to rise, and the oil and gas will fill the whole space and cannot be discharged, which will increase the pressure in the tank shell and shorten the cycle of lubricating oil consumption, addition and replacement. After the engine ventilation system is blocked, the movement resistance of the piston is increased and the fuel consumption is increased. Due to the pressure difference between the inside and outside of the box shell, oil leakage often occurs at the poor seal.
4. Properly solve the problem that the union nut of various oil pipe joint sealing vehicles is often disassembled, which is easy to slip and break, resulting in oil leakage. Replace the union nut, solve its conical surface seal by grinding, and press the nut to solve the seal.
5. Prevent the hub from throwing oil. Too much lubricating oil in the hub bearing and cavity, improper installation and configuration of its oil seal, poor quality, aging and failure, frequent braking leading to excessive temperature of the hub and loose axle nuts will basically lead to oil throwing of the hub.
