Why is My Car Leaking Oil?

Discovering a pool of oil underneath your car can be both concerning and frustrating. Not only can oil leaks create a mess, but they can also indicate underlying issues that need immediate attention. Understanding the causes of oil leaks in your car is crucial to maintaining its performance and preventing further damage.

There are several reasons why your car may be leaking oil. One common cause is a worn-out or damaged gasket or seal. Over time, these components can deteriorate due to age or excessive heat, leading to oil leaks. Another potential culprit is a loose or faulty oil filter, which can cause oil to seep out. Additionally, a cracked or damaged oil pan can result in oil leaks.

Other causes of oil leaks include a malfunctioning or worn-out oil pressure switch, an overfilled oil reservoir, or a damaged oil cooler. It is also possible for leaks to occur due to loose or improperly installed oil drain plugs or oil filter caps. Lastly, damaged valve covers or seals can contribute to oil leaks.
