What is an intake manifold gasket?

For the engine to run, the intake manifold has to be properly sealed to the cylinder head. The intake manifold gasket does this. It may be made of rubber or paper.

How does the intake manifold gasket work?

The intake manifold is a distribution system for air, and sometimes fuel. As the throttle body opens, the engine intake stroke sucks in air through the intake manifold. Cars that don't use direct injection will distribute fuel this way as well, but this system is becoming less common.

Negative pressure, or a vacuum, builds up inside the intake manifold, and the manifold gasket is used to prevent any unwanted air from entering the system.

What are the symptoms related to a bad intake manifold gasket?

Problems with the intake manifold gasket can create the following symptoms:

  • Illuminated check engine light
  • Erratic engine performance
  • Oil and coolant leaks
  • Poor gas mileage
  • Stalling

How is a intake manifold gasket replaced?

Typically, the intake manifold will have to be removed to replace the gasket. This can be a large job that may involve draining the engine of coolant and oil and removing many engine components.

Many vehicles, however, are designed with plastic intake manifolds that do not have oil passages or coolant passages, and are much faster and more cost effective to remove and reinstall. 

RepairPal recommendations for intake manifold gasket issues

When replacing the intake manifold gasket, the fuel injectors may require removal, and using OEM replacement fuel injector seals is the best option. When working with fuel, the battery should always be disconnected, and proper precautions should be taken against fire and inhalation hazards.

Can I replace the intake manifold gasket myself?

No, this job should be left to a professional technician.
