Oil Pan Gasket

The oil pan is the part of the engine responsible for holding whatever oil is not running through the engine. This is true whether the car is on or off, and its job doesn’t go much further than that. The oil pan is located at the bottom of the engine, and can hold anywhere between 3 and 10 quarts of oil. That variation in size is dictated by the size of the engine, as bigger engines need to run more oil through them in order to function correctly. Oil pans, and oil pan gaskets are parts of the car that rarely malfunction or suffer damage during the life of a car, which as most drivers know, isn’t exactly a common thing.

There are two major reasons why you might have to replace the oil pan or its gasket. The most common one is that a problem has developed with one or the other. If your oil is leaking, however, either the oil pan or its gasket is the likely cause. As mentioned earlier, problems here are uncommon, but they do happen from time to time. The other reason to replace it is for performance. Some racers like to install bigger oil pans, as that increases heat reduction as the oil supply increases.

If you’re looking to replace the oil plan for any reason, you’ll need to remove both that an the oil pan gasket, and vice versa, since the two are connected. Removing the oil pan gasket isn’t always the easiest job, but it is one that most people who have a decent knowledge of cars should be able to do. As a car knowledge barometer, you should at least be able to change your own oil if you’re going to attempt to change the pan and/or gasket. Also, it will be incredibly valuable to have your vehicle’s owner’s manual, as that will likely provide much of the information you’ll need.

When you’re ready to remove your oil pan and gasket, the first steps are to elevate your car and drain the oil. You should also place some stopgap object, like a brick, around your tires to keep it from moving. The next step is where the owner’s manual might come in very handy. Once you drain the oil, there may be some parts of your car that block you from reaching the pan itself, most likely part of the exhaust. If this is the case with your car, it might be more difficult than usual to remove the pan, but it should still be doable. You’ll need to remove whatever panel is in the way of the pan.

Once you get to the pan itself, you’ll need to unscrew whatever bolts are attaching the pan to the engine, as well as remove whatever hose is also attached to the engine. You’ll need to be very careful when removing the oil pan, because oil pans are usually made of soft metals, and can bend, puncture or break very easily. When you remove the pan, the gasket should come with it, if your car has one. Some cars, especially newer ones, use a sealant in place of the gasket.

It is possible to repair either the pan, and usually fairly easy, but if the problem lies in the gasket, the best option is to replace it entirely. Oil pan gaskets are very cheap and easy to find. Any auto parts store will carry gaskets, and they’ll usually cost between $5 and $30, and sealants are usually in the same price range.  The most important thing to remember when buying a gasket is to make sure it is the correct part for both your make and model. As long as you remember to get that right, installing it is easy to figure out from the placement of the gasket in the pan.
