Understanding the Basics of Oil Leaks
An oil leak is a condition where oil seeps out of the engine, often due to a breach in the engine’s seal or gasket. This can be caused by a variety of factors, including wear and tear, age, and neglect. When the oil leak only occurs when the car is running, it can be a sign of a more complex issue.
Why Oil Leaks Happen
Oil leaks can occur due to a variety of reasons, including:
- Worn-out engine components: Over time, engine components such as piston rings, cylinder walls, and valves can wear out, causing oil to leak out.
- Faulty seals and gaskets: Seals and gaskets can deteriorate over time, allowing oil to escape from the engine.
- Loose or damaged oil drain plug: A loose or damaged oil drain plug can cause oil to leak out of the engine.
- Clogged oil filter: A clogged oil filter can cause oil to leak out of the engine.
- Low oil level: A low oil level can cause the engine to suck in air, which can lead to oil leaks.
Types of Oil Leaks
There are several types of oil leaks, including:
- Engine oil leaks: These are the most common type of oil leak and occur when oil seeps out of the engine.
- Transmission oil leaks: These occur when oil leaks out of the transmission.
- Brake fluid leaks: These occur when brake fluid leaks out of the brake system.
