Finding an Exhaust Leak

For you to find an exhaust leak, you need to ensure that the car is parked on a firm and level surface. Check to see if the vehicle is in a park mode and engage the parking brake. Start the car to determine the source of the leak.

Look for puffs of smoke through the whole exhaust system from under the vehicle. Check the engine oil and go through the tailpipe. If you notice any smoke escaping, that’s the source of the leak. Make sure that you keep your hands away from any working parts when running a vehicle as this could expose you to injuries.

Vehicles with a lower bottom may have leaks because of the underside being exposed to speed bump or potholes. Rust is also another cause of leaks.

After you’ve found the source of the leak, it’s time to assess the extent of the damage. If your piping has a huge amount of rust, you may need to get a professional to replace the entire exhaust component. However, you can repair small holes using an exhaust pipe or repair putty.
