What is the job of replacing an intake manifold?
Replacement involves unbolting the intake manifold from the cylinder head. On a four-cylinder engine, the job is simple. Except that, the position of the intake manifold on the side of a vertically oriented engine can make access difficult.
What Goes Wrong With Intake Manifold Gaskets?
The intake system is under vacuum while the engine is running, so any leak from the intake manifold gasket will allow air to enter the system. The engine monitors the air as it flows through the intake tube, so any air that enters after that is un-monitored and causes problems with the fuel-air mixture.
