Why Does the Engine Leak Oil?
2 Answers
As the engine is used, the oil has strong permeability, and generally, a small amount will seep out from the oil seal. Here is some relevant information about engine oil leakage: 1. If it is a slight oil seepage or contains oil vapor, it will not have a significant impact on the engine. It is recommended to continue using it and observe the situation. 2. For oil seepage or slow leaks, the location of the leak should be identified, usually at the joints. 3. If the oil leakage persists for a long time, it is recommended to have it inspected and repaired at a professional repair shop. 4. Although this oil seepage does not affect the overall operation of the engine, it will deplete the oil in the lubrication system (the leaking fluid is definitely engine oil). Over time, this reduces the effectiveness of the lubrication system and ultimately affects the engine's lifespan.
I find engine oil leaks quite common, mainly caused by aging seals. After years of use, rubber oil seals harden and crack due to heat and vibration, allowing oil to seep out. If the oil pan gasket isn't properly aligned during installation or the bolts loosen, leaks can also occur. I've seen many cases where prolonged rough driving causes bolts to loosen, leading to oil line leaks. Overfilling oil isn't good either - excessive oil pressure can break through seals. Additionally, loose oil pipe connections or filters are another cause, especially in some car models with design flaws where connection points are weak. Regular maintenance like checking these areas can prevent major issues. Rubber components harden more easily in winter, so timely replacement saves money and hassle.
