What Causes Engine Gasket Oil Leakage?
2 Answers
There are two basic scenarios for automobile engine oil leakage. Automobile engine oil leakage: When there are clearly visible oil stains on the surface of the automobile engine casing, and if these stains reappear shortly after being cleaned, or even in severe cases where oil drips like water droplets, the vehicle should be sent for repair as soon as possible. Automobile engine oil seepage: If the engine casing only has minor oil stains, it indicates that the oil leakage is not particularly severe. The amount of seepage is minimal and hardly noticeable at this stage, posing almost no impact on the engine. The most direct and effective solution is to replace all the sealing rings. Urban traffic congestion, with frequent stops and starts, necessitates constant gear shifting. Modern vehicles have an increasing number of gears, leading to more frequent gear shifts, greater working pressure inside the transmission, higher temperatures, and accelerated aging and deformation of the rubber seals in the transmission.
Last time my car had a problem with the cylinder gasket leaking oil, it took a long time to fix. The main reason was that the engine temperature was too high during operation, which deformed the sealing gasket, causing oil to seep out through the gaps. Other common factors include loose screws during installation, the gasket not being secured properly; or prolonged use leading to rubber aging and cracking; if maintenance is improper, such as coolant leakage causing the engine to overheat, it can also accelerate the leakage. I recommend checking for wet spots near the cylinder head when you see oil stains dripping under the engine, and it's best to replace the gasket in time. Otherwise, severe oil leakage can affect heat dissipation, and you might end up needing a major engine overhaul, which is expensive and risky. Regular oil changes and checking the cooling system can prevent this kind of issue.
