Learn the possible reasons why your vehicle has an oil leak.
Valve cover gasket leaks
A common source of oil leaks occurs due to valve cover gasket wear. Gaskets are constantly exposed to high temperatures and pressures from hot fluids. This causes the valve covers to warp over time where the surface connects to the cylinder head, making it no longer flat, leading to oil leaks. Usually, it starts off as small drips under your car. Additionally, the gasket may lose its elasticity and sealing ability, leading to oil leaks. Don’t dismiss even small oil leaks because it can turn into a big expense the longer it’s ignored.
Oil filter wear
Oil filter wear is also a common culprit of oil leaks. If your oil filter is the wrong size or crooked, it will lead to oil dripping. During oil changes, a mechanic will change the filter and check that it’s not loose or misaligned, ensuring the oil filter fits properly.
Drain plug or filler cap damage
The drain plug is located at the base of the oil pan. If it has worn out, loose, or misaligned treads, that can be another cause of an oil leak. While your car is running, the engine's pressure can also cause oil leaks if your vehicle’s filler cap is loose, missing, or broken.
