How to Replace the Intake Manifold Gasket on a Saturn
The intake manifold gasket on your Saturn is a malleable material set in between the air intake manifold, the cylinder head and the engine block. The intake manifold gasket prevents air and fuel from leaking by sealing the gap between the cylinder head and the engine block. If your intake manifold is leaking, the car will experience a decrease in gas mileage and poor engine performance if the intake manifold gasket is leaking.
