Common Causes of Oil Leaks

Car leaking oil when parked? Oil leaks are a common issue that many car owners face. Understanding the causes is vital to prevent further complications.

Worn Out Gaskets and Seals

Gaskets and seals prevent oil from leaking out of the engine. Over time, they wear out due to heat and pressure. Cracked or deteriorated seals can lead to significant oil leaks when your car is parked. Regular inspection and maintenance can prevent this issue.

Loose or Damaged Oil Filter

The oil filter helps remove contaminants from the engine oil. If it’s loose or damaged, oil can escape and drip onto the ground. Replacing or securing the oil filter is an easy fix for this problem.

Overfilled Oil Levels

Overfilling the oil reservoir creates excessive pressure in the engine. This pressure can push oil past seals and gaskets, resulting in leaks. Always fill oil to the recommended level indicated in your car manual.

Cracked Oil Pan

The oil pan collects oil that circulates in the engine. A cracked oil pan can be caused by road debris or wear and tear. If damaged, it can allow oil to seep out, causing visible leaks. A professional inspection is often required for repair or replacement.
