What is an Exhaust Leak?

An exhaust leak is a common issue that can lead to various problems for your vehicle. While it might start with minor noises, if left unchecked, it can affect performance, gas mileage, and even trigger the ‘check engine light’. In the worst-case scenario, a significant leak could introduce dangerous carbon monoxide into the cabin. Therefore, identifying the causes and signs of an exhaust leak is crucial for vehicle safety and performance.

Signs of an Exhaust Leak

One of the first indicators of an exhaust leak is a strong, unpleasant odor coming from the exhaust pipe. This often signifies that exhaust gases are escaping improperly. Additionally, the illumination of the check engine light is another sign to look for. If this occurs, it is imperative to have the exhaust system inspected promptly to avoid potential environmental damage. Another key signal is unusual noises emanating from the exhaust pipe, especially when driving.

How to Find an Exhaust Leak

To locate an exhaust leak, start by inspecting the exhaust system for any visible signs, such as black soot around the pipes. If you need a closer look, consider lifting your vehicle for better access. Pay special attention to flex joints, as leaks can often be concealed there. Once identified, the approach to repair will depend on the size of the hole. Small leaks can typically be managed using exhaust tape, while larger issues may require aluminum patches or professional assistance.
