#Manifold exhaust leak how to

However, I also suspected the leak may have been around the manifold, and unfortunately, I am not really sure how to find a leak at that particular location (no lift for one thing). For a while I have suspected the vehicle may have had an exhaust leak. Contact Seeburg Mufflers to have the problem diagnosed and repaired as soon as possible.I have a 96 Chevy G10 van with a 5.0. If your car has an exhaust leak, don’t wait for the worst to happen. Repairing internal engine damage such as this can often cost well over a thousand dollars, far more than the cost of repairing the leak in the first place. This excess heat can potentially damage the valves that allow exhaust gases to escape from the engine. When an exhaust leak occurs close enough to the exhaust manifold, the system can no longer draw enough heat away from the engine. The exhaust stream also carries away heat produced in your engine’s combustion chambers. When your exhaust plumbing carries fumes away from your engine, it’s doing more than just transporting harmful chemicals. In a worst-case scenario, an exhaust leak in the wrong place can lead to painfully expensive internal engine damage. You may also trigger several computer error codes, which can make the ultimate source of the problem more challenging to track down. In addition to the cost of the repair, poorly functioning oxygen sensors will reduce your gas mileage, sap power from your engine, and potentially cause your vehicle to idle poorly. The longer you ignore an exhaust leak, the higher the chance that your O2 sensors will also require replacement.

Excess fuel in your exhaust stream can coat the tips of the sensors, fouling them and preventing them from producing an accurate reading. Over time, this damages the interior substrate, clogging the unit, and preventing it from operating correctly.Īlthough they aren’t as expensive to replace as a catalytic converter, your O2 sensors can suffer a similar fate. Since catalytic converters operate at extremely high temperatures, unburnt fuel will combust as it enters them. Some extra fuel may sound harmless, but unburnt fuel is a significant threat to your car’s catalytic converters. Since insufficient air is present to burn all of this fuel, unburnt fuel will enter your exhaust stream. When this happens, your car’s oxygen sensors will register a lean condition and add extra fuel to the combustion mixture to compensate. It can also draw excess oxygen into the exhaust system.

Exhaust leaks can be costly for other reasons, but cabin leakage is by far the greatest threat to the safety of your vehicle’s occupants.Īn exhaust leak can do more than just fail to pull combustion byproducts away from your engine. If a hazardous quantity of this gas is leaking into your car, you may not even be aware of the problem. If the exhaust is instead escaping from below the vehicle, it can often find its way inside the passenger compartment.Ĭarbon monoxide is one of the most dangerous byproducts of combustion, and it also kills silently. The typical passenger vehicle is not hermetically sealed and instead relies on the exhaust system to expel gases from the rear of the car safely. If you can smell your exhaust leak inside your car, then harmful exhaust fumes are leaking into your cabin. Below you will find four ways that an exhaust leak can lead to much bigger trouble down in the line. If you’re in the habit of ignoring exhaust problems, then it may be time to reconsider your approach. This common problem can also be harmful to you and potentially create costly issues for your car in the future. Of course, the sound alone isn’t the only reason to fix a leak in your exhaust system. Most people don’t want to announce their presence on every street they drive down, especially if they’re just on their way to work. Exhaust leaks are loud, annoying, and embarrassing.
