Why Is My Car Leaking Oil When Parked

Have you ever asked: why is my car leaking oil when parked? Oil leakages in cars are usually associated with serious problems that should not be ignored. This common occurrence is a definite sign of mechanical defects and could happen for several reasons. Furthermore,  finding the exact spot of the oil leaks can be difficult, especially for inexperienced car owners. 

In this article, common reasons behind oil leaks in cars and ways to prevent such in the future will be discussed in detail. Without further ado, let’s dive right in!

Oil leakage when the vehicle is idle is a common problem faced by car owners that must be fixed once discovered. Oil leaks are usually associated with gasket problems or damaged seals on the car engine. However, there are other mechanical failings that can cause oil leakage in parked vehicles. In this regard, let’s check out some common problems that can cause your car to leak oil when parked.

Degraded Oil Pans

Oil pans are susceptible to degradation due to where they are positioned on the engine. This is one of the major causes of oil leakage as it may get cracked as a result of constant driving on rough roads. Oil pans are found at the bottom part of the engine which makes it susceptible to quick wear and tear through consistent hits of debris. An aluminum oil pan cracks up over time while oil pans made of steel could get rusted after a long time. Furthermore, the source of oil leaks may be oil pan gaskets and the best resolution is to seek professional assistance as promptly as possible.

Defective Engine Gaskets

Damaged engine gaskets are one of the usual reasons a car could leak oil when parked. Car engines generate excess heat while driving and this could result in degeneration of the engine gasket. Practically, the metal components of the car engine usually get stretched as a result of the high temperature of the engine block when you stopped the vehicle.

This process ultimately led to an inevitable increase in pressure on the gasket. The usually tightened metal components and the seal of the engine will lose grip as a result of this decrease in temperature. The gaskets tend to wear out easily and the engine reacts to this anomaly by leaking oil. A problem of this magnitude requires a quick fix and the service of a professional mechanism should quickly be sought to prevent the vehicle engine from serious damage.

Damaged Oil Seals

Bad verve or ring seals can also result in oil leakages when a vehicle is parked. However, the leakage may not be visible if the gasket is in a top condition without cracks or holes. In this case, the combination process of the car engine will burn up the leaked oil, Which makes regular inspection of vehicles important for early detection of such problems.

Damaged Oil Filters

Loosened oil filters can also cause oil leakage when the car is parked. A routine check should be performed to check if the filters are rusted or need to be properly tightened. It is important to change the oil filters once you discovered it is rust to avoid fuel leaks. More importantly, oil filters must be replaced every time you changed the engine oil.

Incorrect Installations

Proper installation of oil gasket is crucial to avoid oil leaks. Also, the oil pan gasket should be moderately tightened.

What Are The Early Signs That My Car Is Leaking Oil?

Heavy smoke from the vehicle’s exhaust can be an early sign of oil leakage. Other signs to look out for include engine overheating and the smell of burning oil.

Closing Thoughts

Car oil leakage when parked is an indication of a default in the car engine. Timely inspection is crucial to identify and fix the underlying cause.
