In order to provide your car with enough power to move, your car burns fuel. During this process, toxic gases are released into the air outside your vehicle after going through a few additional steps to make them safer for the environment.

What Is An Exhaust Manifold?

It is the job of your car's exhaust system to deal with these gases. Typically they will cool them down to a safe temperate and clean them. Once they are ready to be released, the exhaust system will push the gas out of your exhaust pipe.

Since your exhaust system has a huge task at hand, there are a lot of different parts, including the manifolds, catalytic converter, heat shields, joints, tailpipe, flexible unions, mufflers, and more.

All these parts need routine maintenance because they endure harsh conditions, such as high temperatures, and are prone to becoming worn-out a lot faster than other car parts. The exhaust manifolds are typically made out of cast iron or stamped steel to help them withstand extreme temperatures.

If there is a leak in your exhaust system, dangerous and toxic gases could potentially leak into the cabin of your vehicle rather than being dispersed outside the vehicle. Not only will this put your health at risk, but you might find that your car isn't running at its best and discover other problematic symptoms.

Signs My Exhaust Manifold Is Failing

If there is a leak in your exhaust manifold, you will certainly notice some of the signs. Check out our list of the most common symptoms of a leaking exhaust manifold and compare them to the symptoms you have seen in your own vehicle.

  • Abnormal Noises
    If your engine is louder than normal, it could be a sign that your exhaust manifold has a leak. When there is a leak, un-muffled gas could escape from the exhaust system, causing the engine to sound louder or noisier than usual.
  • Poor Fuel Economy
    A leak in the exhaust manifold can reduce your vehicle's fuel efficiency. If you notice you need to take more trips to the gas station than you used to, you might need to have your exhaust manifold checked out by a professional.
  • Strange Smells
    If there is a leak or crack in your exhaust manifold, the gases could be escaping into the outside air before it has been transformed into a less toxic gas. As a result, you might notice a strange smell coming from under your hood.
  • Lack Of Acceleration Power
    Leaks can also cause a lack of engine power. If your car isn't accelerating as it used to, don't ignore it! This symptom can be mild at first, but if you put off your exhaust manifold replacement service for too long, it could worsen.
  • Check Engine Light Turns On
    Sometimes a leak in your exhaust system will cause the sensors in your car to think there is a problem with your engine. If this happens, your check engine light will turn on.
