Having your exhaust system examined will help you find and address any problems before they turn into a bigger issue. Your best defense against exhaust leaks and the problems they cause is to have your service provider inspect the exhaust system on a regular basis. In addition, if one of the hangers securing your exhaust system in place falls off or the rubber isolator section is excessively worn, other parts could weaken or become damaged as they bounce around and take on more vibration and impact during vehicle operation. Driving on rough roads can cause your exhaust system to be subject to shaking and bumps that can cause holes and structural components to weaken, while rust and corrosion damage in exhaust system parts are perfect places for exhaust leaks to form. If you notice any of the following signs, it’s time to make an appointment with your service provider.ĭriving on rough roads and exhaust system components with rust damage are the top causes of exhaust leaks. Keep your vehicle running smoothly – learn to recognize the symptoms of an exhaust leak. ![]() If you live in a state with emissions testing, an exhaust leak can result in failing the test, forcing you to resolve the issue before being able to legally operate your vehicle. Prolonged exposure to these emissions could make you and your passengers sick. Many of these harmful gases are odorless, which means that you won’t realize they are leaking into the passenger cabin. A properly working exhaust system is essential for the safe operation of your vehicle.Īn exhaust leak can cause dangerous gases to enter the atmosphere before being properly treated, which can cause problems like fumes in the cabin and failed emissions inspections. They can help as well, but I've found noise is usually transmitted throughout the metal of the engine, so it can help pinpoint sometimes, but other times it's not as apparent.Responsible for reducing the emissions your vehicle produces, your exhaust system makes these toxic gases less harmful before they leave your car and are released into the environment. There are also automotive stethoscopes which are very cheap at places like Harbor Freight. This will help localize where the noise is coming from. Put one end of it up to your ear and wave the other end around in the engine compartment. If you grab a piece of rubber hose about 3' long, you can use that as a diagnostic aid to help you pinpoint where the noise is coming from. If you aren't seeing any of these things, you can pretty much eliminate the exhaust as your problem. You'll also be seeing more soot around the inside of the tail pipe due to richness of the burn. This messes with your O2 sensors, which makes the computer dump more fuel in to the system. Even though there is pressure where the leak is at, as the exhaust flows by, it will draw air in with it (there's a physics term for this, but I'm not remembering it right now - it works like a venturi in a carburetor). This seems counter-intuitive, but it is actual. This is because if there is a leak, fresh air will be getting into the system fouling up the fuel trims. If you have an exhaust leak, you're vehicle will most likely be getting worse gas mileage. The next thing you need to do is check your trim levels. If you don't see any, it doesn't mean you don't have an exhaust leak though. Plus, IIRC, the exhaust is on the back side of the engine next to the firewall, which makes it even harder to see. On your car and most cars with turbos, this is going to be hard to see because of all the supporting "stuff" which is there. This is a usual suspect area on most cars with an exhaust leak. The next place you need to look at is where the header meets the head. This eliminates a lot of "stuff" to look at. While you may have a leak downstream of the turbo, you'll not get a ticking noise from it. The turbo, due to it's nature of homogenizing the exhaust flow, will pretty much eliminate any ticking noise which may be due to an exhaust leak. Seeing as how your car has a turbo, the only place it would be leaking and you'd hear a ticking noise is pre-turbo, so the exhaust manifold at the head (header) and the down pipe on the hot side to the turbo.
