What is an Exhaust Manifold Gasket?

The exhaust manifold gasket seals the exhaust manifold(s) to the cylinder head(s). The exhaust manifold gasket is responsible for keeping the dangerous exhaust gases from leaking out before they pass through the converter. If the exhaust manifold gasket fails, it can affect the performance and drivability of the vehicle and could potentially leak gases into the cabin.  Leaks from the exhaust manifold can also affect emissions by allowing oxygen sensor readings to become skewed.

Symptoms  of a Bad Exhaust Manifold Gasket 

With repeated exposure to heating and cooling cycles, the exhaust manifold gasket can become stressed and fail.  Signs of a  bad exhaust manifold gasket include:

  • Excessive engine noise
  • Diminished engine performance, loss of acceleration and reduced gas mileage
  • A burning smell
  • Exhaust fumes in the vehicle cabin
  • A ticking/exhaust noise present that goes away as the engine warms up
  • Check Engine light on

Checking for Exhaust Manifold Leaks

To check for exhaust manifold leaks, start by visually inspecting the engine compartment (once it has cooled), looking for black soot around the exhaust manifold. You should look for obvious cracks in the manifold, loose/missing/broken fasteners at the

exhaust manifold and check for damage around the exhaust ports. Some exhaust manifolds may have heat shields on them that require removal for a better look at the manifold’s condition. Use of a flashlight and inspection mirror may help while looking under the manifold.
