What can a leaking intake manifold cause?
Difficulty Accelerating. A leaky intake manifold gasket often makes it more difficult for your car to accelerate, even if the problem has not reached the point where it causes misfires to occur. Such power loss stems from the air leaking out of the intake manifold.
What will happen to the engine if the intake manifold gasket fails?
A damaged gasket often fails to create an airtight seal between the manifold and the engine. This seal failure allows air that should be entering the engine to escape instead. Such a leak alters the engine’s air–fuel ratio — one of the most important factors in promoting complete combustion.
