The intake manifold is responsible for distributing air and fuel to the engine’s cylinders. A leak in the intake manifold can allow air to enter the engine without being mixed with fuel, which can cause the engine to run lean. This can lead to a loss of power, poor fuel economy, and rough idling. In severe cases, an intake manifold leak can also cause the engine to stall or overheat.
Causes of Intake Manifold Leaks
There are a number of things that can cause an intake manifold leak, including:
- A cracked or damaged intake manifold
- A loose or missing intake manifold gasket
- A warped intake manifold flange
- A faulty intake manifold bolt
Symptoms of Intake Manifold Leaks
