Exhaust Manifold Gasket Replacement
What is an exhaust manifold gasket?
The exhaust manifold is the collector for the engine’s exhaust gas. It is the first step in the exhaust system, and the last step the engine takes to produce power.
How does the exhaust manifold gasket work?
As the engine pumps hot exhaust gases out of the cylinder head, the exhaust manifold receives it, and pressure builds inside the manifold. The metal gasket expands with the cylinder head and manifold, to fill the tiny gap between them, so back pressure may build without the gas escaping the exhaust system,
When the exhaust manifold gaskets are leaking, you will hear a ticking or tapping noise, especially when the engine is cold. The noise may partially or totally disappear when the engine is warmed up.
