What are the causes of automobile oil leakage? The reason is introduced.
First, loose screws, damaged gaskets or improper installation will lead to oil leakage around the valve cover, so it is necessary to tighten the screws in time.
The second is the oil leakage caused by the front and rear oil seals of crankshaft and improper installation of oil seals.
3. The lubricating oil filter, pressure limiting valve and sensor leak oil. If it leaks due to improper installation, replace and reinstall the gasket and properly handle it.
Fourthly, loose bolts, cracks and holes in the oil pan can also lead to oil leakage.
5. Loose, broken or poorly matched tubing causes oil leakage, and the gasket at the joint between gasoline pump and cylinder body is damaged and leaked.
6. The oil seal of the rear oil cover of the cam bearing leaks oil, the thickness of the oil seal may be insufficient, the outer edge is not well matched with its hole, or it corrodes and leaks oil.
What are the causes of automobile oil leakage? Risk of engine oil leakage.
The main hazard is the loss of engine oil, which causes waste. Serious shortage of engine oil may lead to engine damage. It is not caused by oil leakage, but by insufficient oil pressure after oil leakage. Just pay close attention to the oil level. Because the 307 has an oil level display, it avoids the unconscious situation that the oil level is lower than the normal level, and there is an alarm light when the oil pressure is insufficient.
What are the causes of automobile oil leakage? Treatment methods.
1. Determine the oil leakage position and wipe off the oil traces at the oil leakage position, and then start the engine to check the oil leakage position: if the oil leaks from the front and rear oil seals of the engine, the oil seal is damaged; If it leaks from the joint of crankcase and cylinder block, it means that the bolt is loose or the gasket is damaged; If it leaks from the joint between the gasoline pump and the cylinder block, the bolt is loose or the gasket is damaged; If it leaks from the oil filter, it may be that the oil filter is damaged or the sealing apron is damaged.
2. Take measures to remove and replace oil seals, gaskets or sealing rings that are damaged; Tighten loose bolts; If the attachment itself is damaged, it needs to be replaced with a new one.
Today, Bian Xiao's introduction ends here. What is the reason for the oil leakage of the car introduced by Bian Xiao? There is also a big difference between automobile oil leakage and engine oil leakage. Oil leakage is mainly reflected in the fact that the engine oil has not decreased rapidly, only a small amount of oil stains can be seen at the engine seal, but no obvious oil stains are found on the engine guard plate or on the ground. If you want to know more, please pay attention to Bian Xiao.
