Top Signs of an Exhaust Leak


Top Signs of an Exhaust LeakThe exhaust system has a very important job that starts under the hood and ends at the back of the car. The task at hand is routing harmful fumes produced by the engine under the passenger cabin, through the catalytic converter and out of the tailpipe. Measurements taken in the exhaust help to establish the correct air and fuel mixture and leaks can result in numerous engine issues. However, it is important to understand that while a leak is bad for your car, it can be much worse for you and your passengers. Exhaust fumes are deadly and often times undetectable until it is too late. If you notice any of these signs of an exhaust leak don't hesitate to get to a repair shop for proper diagnostics and repair.

Loud Engine Rumbling

One of the most common signs of an exhaust leak is if the engine begins to sound much louder than normal. Since the exhaust system is designed to dampen engine noise a leak in it will cause the increased volume. This will be most noticeable during rapid acceleration, such as when getting on the highway.

Gas Pedal Vibrations

Another symptom of an exhaust leak is if you can feel the gas pedal vibrating, even slightly. The sensation is caused by exhaust fume rapidly existing the system through a small hole, causing reverberations. A bad leak could also cause steering wheel vibrations or the whole car may shake.

Decreased Fuel Efficiency

While there are many things that can result in a loss of fuel economy an exhaust leak will often cause a massive drop. This is because the oxygen sensor in the exhaust system will detect excessive oxygen if there is a leak, which will cause the vehicle to use more fuel than is necessary.

Check Engine Light

The check engine light is a sign of an exhaust leak, but it can also represent many other problems. Anytime the check engine light comes on it is important to get it checked out to find out what is going on. Many times the issue will start small and grow into something worse, such as a bad oxygen sensor causing a failed catalytic converter.
