What is an intake manifold gasket and what does it do?
The intake manifold is responsible for evenly pumping a fuel and air combination into the engine cylinders to maintain engine cooling and prevent overheating.
The intake manifold gasket is made of molded plastic or aluminum. It seals the cylinder engine heads to the intake manifold and creates a tight vacuum to prevent any air, oil, or engine coolant leaks.
It connects the openings of the manifold to the engine heads, ensuring that the fuel and air flow directly into the cylinders and nowhere else.
What are the symptoms of a bad intake manifold gasket?
Intake manifold gaskets experience a lot of temperature expansion and contraction, so it’s not uncommon for them to need replacement. Luckily, there are a few symptoms of a leaking intake manifold gasket, so you’re not likely to miss the problem:
Internal and/or external coolant leaks
An illuminated Check Engine light
Engine stalling or misfiring
How often should the intake manifold gaskets be replaced?
Your intake manifold gaskets will likely need to be replaced every 50,000 to 75,000 miles because they get worn out over time and with repeated use.
Can I replace my intake manifold gaskets myself?
If you consider yourself a home mechanic with strong DIY skills, you can definitely replace an intake manifold gasket on your own.
However, for the average car owner, it’s best to visit a reputable auto shop and let certified technicians handle it.
