The Symptoms of a Leaking Exhaust Manifold

You may never have to deal with a leaking exhaust manifold, but we can help if you do. The number one enemy of the exhaust manifold is heat, even though it deals with tremendous heat and pressure all the time. Heat can also damage the exhaust manifold gasket. Below, we are going to list the signs that you’ve got a problem with either the manifold or gasket.

Rotten Performance

The exhaust manifold and its gasket are designed to deal with the heat and pressure of the exhaust as it pushes it through to the catalytic converter. If there is excess heat in the engine, this can crack the manifold or gasket. When this happens, exhaust escapes out of the manifold and fills the engine. Unfortunately, this creates a problem with your engine’s performance.

Rotten Fuel Economy

Your engine’s performance will start to sputter and lag. This is especially true when you accelerate. Unfortunately, even though the engine is performing poorly, it will consume more fuel. This will leave you with rotten engine performance alongside rotten fuel economy.

Popping or Tapping

The exhaust manifold or gasket may make a noise as the exhaust escapes out of it. When this occurs, the exhaust may pop or tap. In addition, you may hear a hissing noise coming from the engine. The best time to listen for these noises is when you first start your automobile.

Strong Burning Odors

As we mentioned above, the exhaust is extremely hot. Consequently, as it fills the engine, it heats it up. The temperature gauge needle on your dashboard is going to rise. You will also smell strong burning odors coming from the engine. In fact, you may even smell engine parts melting.

Strong Exhaust Odors

In addition to the burning odors, you may start to smell the exhaust inside your automobile. When the engine fills with exhaust, it is easy for the exhaust to be drawn through the vents by the ventilation system. This can make you sick while you are driving your vehicle.

Check Engine Warning

Finally, various system sensors will detect that the engine is having a hard time running. They will alert the engine control module of the problems, and the module will turn on the check engine light. This light will remain illuminated steadily until you replace the manifold or gasket.

We can do that here at our shop, so call us today to set up a service appointment.
