Uptown Imports can help if your import has developed an exhaust manifold leak. If the import’s engine is running too hot, it can crack the exhaust manifold or the manifold gasket. Excess heat is the most common cause of an exhaust manifold leak. You may not realize that the manifold is leaking until you notice one or more of the signs of a leaking exhaust manifold below.
Reduced Engine Performance
When the exhaust manifold starts to leak, the engine’s exhaust gases are released into the engine rather than out of the tailpipe. Consequently, this will fill the engine with exhaust that directly affects its ability to produce combustion. As such, you will notice a reduction in your import’s engine performance while you are driving it. Replacing the leaking manifold will resolve the problem.
Reduced Fuel Economy
Unfortunately, until such time as you bring your import to our shop so we can repair the issue, your import will also suffer from a reduction in fuel economy. This is because the engine is not running efficiently. An inefficient engine will use more fuel as it struggles to produce power.
Strong Burning Odors
A leaking exhaust manifold or manifold gasket will also cause the engine to overheat. This is because the exhaust that is filling the engine is extremely hot. It will heat up metal parts and melt parts that are susceptible to heat. Consequently, you will smell strong burning odors coming from the engine while you are driving your import. The import’s engine temperature will also rise.
Strong Exhaust Odors
Another thing that you may smell is the import’s exhaust in the passenger cabin. This can make driving your import dangerous. The exhaust has not been treated yet if it is leaking out of the exhaust manifold, so it will be filled with carbon monoxide that can make you sick.
Strange Start-Up Noises
If you believe that your import has an exhaust manifold or gasket leak, listen to the engine carefully when you start the import. The exhaust will make strange noises that sound like hissing or tapping as it escapes from the manifold while the manifold is cold.
Check Engine Warning
Finally, the problems discussed above are going to cause system sensors to report errors to the engine control unit. The engine control unit will be unable to resolve the problem so it will turn on the check engine light.
