Why is my car leaking oil

Experiencing your car leaking oil can be concerning, but understanding the reasons behind it can help you address the issue and prevent further damage.

Reasons why you car is leaking oil

Engine seals

One common reason why your car may be leaking oil is due to worn-out or damaged engine seals and gaskets. These seals are important for keeping oil contained within the engine and preventing leaks. Over time, seals and gaskets can deteriorate due to heat and pressure, causing them to crack or become brittle. When this happens, oil can seep out and create a leak.

Oil filter

Another possible cause of oil leaks is a loose or improperly installed oil filter. The oil filter is responsible for trapping contaminants and debris from the engine oil. If the oil filter is not securely tightened during installation or becomes loose over time, it can cause oil to leak from the filter housing. Checking the oil filter and making sure it is properly installed can help preventing car leaking oil

Additionally, damage to the oil pan can lead to oil leaks in your car. The oil pan is located underneath the engine and stores the engine oil when the car is not in operation. If the oil pan is punctured or damaged by road debris or improper maintenance practices, it can cause oil to leak from the bottom of the engine. Inspecting the oil pan for signs of damage and replacing it if necessary can help resolve the issue of oil leaks.

Worn out engine parts

Furthermore, worn-out or degraded engine components, such as piston rings or valve seals, can contribute to oil leaks. These components play a key role in maintaining proper engine compression and sealing in combustion gases. If piston rings or valve seals wear out or become damaged, they can allow oil to pass into the combustion chamber or leak externally from the engine. Addressing engine component wear through regular maintenance and timely repairs can help prevent oil leaks.

It’s also important to consider the condition of the crankshaft seals and camshaft seals in your car’s engine. These seals are responsible for preventing oil from leaking out of the crankshaft and camshaft housings. Over time, these seals can wear out or develop cracks, allowing oil to leak from the engine. Inspecting and replacing worn-out crankshaft and camshaft seals can help eliminate oil leaks and maintain engine performance.

Oil maintenance

Moreover, improper oil maintenance practices, such as overfilling the engine with oil or using the wrong type of oil, can contribute to oil leaks. Overfilling the engine can cause excess pressure within the crankcase, leading to oil leaks from seals or gaskets. Using the wrong viscosity or grade of oil can also affect oil flow and lubrication properties, potentially causing leaks or engine damage. Following manufacturer recommendations for oil change intervals and using the correct type and amount of oil can help prevent oil leaks in your car.
