Why Your Car Might Be Leaking Oil
Finding oil spots under your car can be frustrating and concerning. Many drivers ask, “Why is my car leaking oil?”, and the answer usually points to worn seals, gaskets, or other engine components. Even small oil leaks should never be ignored, since low oil levels can lead to serious engine damage.
At Round Rock Auto Center, we help drivers find the source of oil leaks and repair them before they cause bigger problems.
Common Causes of Oil Leaks
Oil circulates through multiple parts of your engine, so leaks can happen in several areas. The most common include:
Worn valve cover gasket – Allows oil to seep down the engine block.
Oil pan gasket leaks – Oil may drip from the bottom of the engine.
Damaged oil filter or drain plug – Incorrect installation or worn seals can cause leaks after an oil change.
Crankshaft or camshaft seals – Leaks around these seals can cause steady oil loss.
PCV valve issues – Pressure buildup can force oil past seals and gaskets.
Blown head gasket – A more serious cause that may mix oil with coolant.
How to Spot the Source of the Leak
A few clues can help determine where the oil is coming from:
Oil on the ground under the car – Likely oil pan or drain plug.
Burning oil smell – Oil dripping onto hot engine parts.
Blue smoke from exhaust – Oil leaking into the combustion chamber.
Rapid oil loss – May indicate a major seal or gasket failure.
Why You Should Fix Oil Leaks Quickly
Ignoring an oil leak can:
Starve the engine of proper lubrication.
Lead to overheating and engine wear.
Cause fires if oil drips onto hot exhaust parts.
Make a small, affordable repair turn into a costly engine rebuild.
