What Causes Oil Leaks?
Oil leaks can occur due to various reasons, including worn-out engine components, damaged seals, and faulty oil pumps. Here are some common causes of oil leaks:
| Causes of Oil Leaks | Description |
|---|---|
| Worn-out Engine Components | Oil leaks can occur when engine components such as piston rings, cylinder walls, and valve stem seals wear out over time. |
| Damaged Seals | Oil leaks can also occur when seals around engine components such as valve covers, oil pans, and cylinder heads become damaged or worn out. |
| Faulty Oil Pumps | Oil leaks can occur when the oil pump fails to circulate oil properly, causing oil to leak out of the engine. |
| Loose or Damaged Oil Filter | A loose or damaged oil filter can cause oil leaks, as the filter may not be able to filter out contaminants properly. |
