What Causes Oil Leakage Inside the Engine?

[Michelle]

Automobile engine oil leakage is caused by: 1. Poor sealing: Engine oil leakage is actually a common issue, usually occurring in older vehicles. Generally, it happens when the sealing components lose their airtightness, as oil seals are rubber products that naturally harden, age, or break over time. However, if the leakage is severe, it might indicate a cracked cylinder block, which is a more serious problem. 2. Excessive internal pressure: Engine oil leakage refers to oil seeping outward, a frequent issue during vehicle use. When the engine is running, excessive internal pressure can cause the machine's internal components to bear too much stress, leading the waste pressure to force open the engine's sealing gasket, allowing oil to seep out. Severe leakage might suggest a damaged cylinder block. 3. Minor seepage: Minor oil seepage is not very serious. If it's just a slight leak, there's usually no need for repair, but regular checks of the oil level are essential. The biggest concern with engine oil seepage is the lack of lubrication due to insufficient oil, leading to wear and tear. Therefore, regularly monitoring the oil level is crucial, and choosing a higher viscosity oil can help alleviate the symptoms.
