Why Does My Car Leak Oil When Parked?

If you notice oil under your car when it’s parked, check around the engine compartment for signs of leaks. A lot of times this is caused by old or damaged seals the part that keeps fluids from leaking out of a part of your engine or transmission system.

It could also be caused by damaged gaskets the little pieces that fit between two parts of your engine or transmission system so they don’t have any gaps between them where air could leak in. If you’ve got either of these issues on your hands, it’s time to take it to an auto repair shop.

How do you know if there’s a leak in your car?

When your car leaks oil while it’s parked, there are a few possible explanations. The first is that the oil filter is damaged or worn out and needs to be replaced. This can happen if you haven’t changed your filter in a long time.

If you have changed your filter recently and this is not the problem, then check the dipstick if it’s dirty or has debris on it, then you know that something else is causing the leak.

If none of those things seem to be true, then you may have an internal engine leak. This could be caused by a cracked head gasket or piston rings, which will require replacement parts from an auto mechanic before you can drive again safely.

Types of Oil Leaks

external and internal. External leaks occur when the outside of your car is damaged and it begins to leak oil. Internal leaks occur when there’s damage to your engine or another part of your car that causes it to leak internally.

An internal leak can be dangerous as well as expensive to repair. If you suspect that your car has an internal leak, it’s best to bring it in for a professional inspection right away you don’t want to risk damaging other parts of your car or putting yourself at risk by driving with an internal leak.

The oil pan gasket has worn out or is damaged

The oil pan gasket is a piece of rubber that sits between the engine and the bottom of your car’s oil pan. The oil pan gasket keeps oil from leaking out of your car when it’s parked, but after enough time and use, the oil pan gasket can wear out or be damaged, allowing excess amounts of oil to leak out of your engine when parked.

If you notice that your car is leaking oil when it’s parked, check for signs that your engine has been leaking excess amounts of oil for a period of time. If you notice these signs and suspect that your problem is related to an old or damaged oil pan gasket, it is important to have this fixed as soon as possible.

This will help prevent further damage to other parts of your vehicle and ensure that you can continue driving safely.

The oil filter housing gasket is worn out or damaged

It’s possible that the oil filter housing gasket is worn out or damaged. The oil filter housing gasket is a rubber seal that keeps oil from leaking out of the engine compartment and onto the ground.

If this seal has become worn or damaged, it can allow oil to seep out of the engine compartment and onto the ground. This can be especially dangerous because it means that more oil will be consumed by your engine, increasing its need for replacement.

The oil cooler lines are leaking

You can tell that the oil cooler lines are leaking because your car will leak oil when parked and you’ll see a puddle of oil under it. The oil cooler lines are a part of the cooling system of your car and they carry coolant fluid through them to transfer heat away from the engine.

When these lines leak, it causes them to lose their ability to remove heat and transfer it away from the engine properly, which can result in overheating and damage to other parts of your engine.


The first thing to do if your car leaks oil when parked is to check the oil level. If it’s low, add oil as needed and run the engine for a few minutes to allow the new oil to circulate. If the level is still low after this, you’ll need to have your vehicle serviced by a qualified mechanic.

If there is no sign of a leak in your vehicle and you’ve checked your oil levels and added any necessary oil, it’s possible that the problem lies with your engine seals or gaskets. In this case, you should take your car for a full inspection by a mechanic who can let you know what repairs are needed to address the issue.
