Collecting engine exhaust gases from multiple cylinders to one location, exhaust manifolds play a significant role in vehicles. Once collected, the manifold routes the gases to the catalytic converter, further converting toxic gases into less poisonous pollutants. As you can see, without the two components or with cracked manifolds or missing catalytic converters, your vehicle will run at less than optimal performance levels.
At Lou’s Custom Exhaust of Milford, our professionals are here to ensure your vehicle continues its best. However, part of the equation also is recognizing when to give our team a call. Here, we provide three telltale signs that your exhaust manifold may require a little TLC.
Performance Loss
While several signs indicate a need for vehicle repair, performance loss is always one of the most obvious. When it comes to cracked manifolds, a reduction in backpressure will result in a loss of power to the engine. This becomes obvious when stepping on the gas and not receiving the expected outcome.
Unusual Odors and Noises
Unusual odors and noises could mean many things when it comes to vehicle maintenance. With manifolds, many of the most common noises include clicking, whistling, or sounds of escaping gases. With the cold season arriving in New England, these sounds become more apparent than in warmer months. However, if you notice the smell of exhaust fumes within the vehicle cabin, it is always the best bet to turn your vehicle off until it can be inspected.
While noises are a telltale sign of required maintenance needs, odors can lead to dangerous outcomes if not addressed immediately.
Visible Cracks
If you suspect an issue with the manifold, don’t be afraid to check things out! Some cracks are large enough to be spotted by an untrained eye, but many – especially in the manifold – are so tiny and around bolts that they can be harder to spot. Either way, if you do notice a crack in any component, you’ll want to reach out to your trusted team of mechanics as soon as possible.
