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 catalytic converter. If the exhaust manifold gasket fails, it can affect the performance and drivability of the vehicle and could potentially leak toxic gases into the cabin. Leaks from the exhaust manifold can also affect emissions by allowing oxygen sensor readings to become skewed.
