Understanding Car Engine Oil Leaks

A car engine oil leak occurs when the engine’s oil system is damaged, allowing oil to escape from the engine and onto the ground. There are several reasons why an engine oil leak may occur, including worn or damaged engine components, loose or damaged oil seals, and clogged oil filters. In this section, we will explore the common causes of engine oil leaks and how to identify the source of the leak.

Common Causes of Engine Oil Leaks

  • Worn or Damaged Engine Components: Over time, engine components such as piston rings, cylinder walls, and valve stem seals can wear out, causing oil to leak from the engine.
  • Loose or Damaged Oil Seals: Oil seals, also known as gaskets, can become loose or damaged, allowing oil to escape from the engine.
  • Clogged Oil Filters: A clogged oil filter can cause oil to leak from the engine, as the filter is unable to properly filter the oil.
  • Tightened or Over-Torqued Oil Drain Plug: If the oil drain plug is tightened or over-torqued, it can cause the plug to become loose, allowing oil to leak from the engine.
  • Cracked or Damaged Engine Block: A cracked or damaged engine block can cause oil to leak from the engine.

Identifying the Source of the Leak

To identify the source of the leak, you will need to inspect the engine and its components. Here are some steps to follow:

  1. Locate the leak: Look for signs of oil on the ground or on the engine components.
