Your Check Engine Light Could Be Telling You That You Have a Cracked Exhaust Manifold

Bring your vehicle to Righter’s Auto Repair right away if the check engine light is on. This light covers engine problems that are not covered by the other dashboard warnings. One thing that will cause the main computer chip to turn on the check engine light is a cracked exhaust manifold. Here are other signs your manifold is cracked and needs to be replaced. Do not worry. We can handle that!

Reduced Performance

A crack in the exhaust manifold will also affect your engine’s performance. Unfortunately, it will reduce the performance. As such, you will end up with a sputtering engine that struggles to perform the faster you drive. The reason why this happens is that the leaking exhaust manifold allows the engine to fill with exhaust. Consequently, this exhaust interferes with engine combustion.

Reduced Fuel Economy

The only time your vehicle is going to get top gas mileage is when the engine is running efficiently. An engine filled with exhaust does not run efficiently. This means that you will not only suffer from poor engine performance but also from poor gas mileage. If you keep track of your mileage, you will notice the difference right away. Otherwise, you may notice that you fill the tank more often.

Tapping, Hissing, or Squealing

A cracked exhaust manifold is also going to make strange noises in the engine. These noises are most noticeable when you start up the engine because the manifold has not had time to heat up and expand. When the manifold expands, it may seal the crack. Before this happens, the manifold will hiss, squeal, or tap. This is the noise of the exhaust leaving the manifold.

Noticeable Burning Odors

If the manifold does not seal up and the engine is filled with scorching exhaust, you will start to smell burning odors. The exhaust will heat up every engine part, whether it is made of metal, plastic, or rubber. The metal parts will overheat and increase the engine’s temperature. The plastic and rubber parts will start to be damaged by the heat and release toxic odors.

Noticeable Exhaust Odors

Speaking of toxic odors, an engine filled with exhaust can also transport that exhaust into the passenger cabin via the ventilation system. When this happens, you will actually inhale your engine’s exhaust while you are driving. This can make you extremely ill.
