Engine Oil Leaks: How to Find and Fix Them



Engine oil leaks can be a frustrating and potentially costly problem for car owners. In this post, we’ll discuss how to find and fix common oil leaks to keep your vehicle running smoothly.

Step 1: Identifying the Location of the Leak

The first step in fixing an oil leak is to determine where it is coming from. The most common places for oil leaks are the valve cover gaskets, oil pan gasket, and rear main seal. A visual inspection of the engine and undercarriage can often reveal the source of the leak.

Step 2: Confirming the Leak

To confirm the leak, you can use a clean rag or paper towel to wipe down the suspected area. Start the engine and let it run for a few minutes, then check for any signs of oil on the rag or paper towel. If oil is present, you have confirmed the leak.

Step 3: Removing the Old Gasket

Before installing a new gasket, the old one must be removed. This can be done by carefully scraping it off with a flat-head screwdriver or gasket scraper. Be sure to remove all traces of the old gasket to ensure a proper seal.

Step 4: Installing the New Gasket

Once the old gasket is removed, the area should be cleaned with a degreaser and a clean rag. The new gasket should then be placed in the appropriate location, making sure it is properly aligned.

Step 5: Reassembling the Engine

With the new gasket in place, the engine can be reassembled. Make sure to use a new oil filter and to refill the engine with the correct amount and type of oil.

Step 6: Testing for Leaks

After reassembling the engine, start it up and let it run for a few minutes. Use a clean rag or paper towel to check for any signs of oil leaks. If no leaks are present, the repair is complete.


When working on your vehicle, it is important to take the necessary safety precautions. Always consult the vehicle’s owner manual for specific instructions and warnings. Make sure the vehicle is on level ground and the engine is turned off before beginning any repairs.

Wear gloves and safety glasses to protect yourself from debris and chemicals. Be sure to use the correct tools and replacement parts for your specific make and model of vehicle.


Engine oil leaks can be a frustrating problem, but with the right knowledge and tools, they can be easily fixed. By following these steps, you can identify and repair common oil leaks, keeping your vehicle running smoothly and prolonging its life. Remember to always consult the vehicle’s owner manual and take the necessary safety precautions when working on your vehicle.
