Do I have to replace my intake manifold gasket?
The intake manifold gasket on a car is supposed to last around 50,000 to 75,000 miles. In some instances, the gasket will fail before this date due to the amount of wear and tear that it undergoes on a daily basis. Some of the intake manifold gaskets are made of rubber, while some are made of a thicker cork material.
When do you need to replace the intake manifold?
Intake manifold, the inner side. If an intake manifold cannot be cleaned or repaired, it must be replaced. An intake manifold is also replaced if one of the failed tuning valves cannot be replaced separately. In some cars, it’s fairly easy, in others it takes more labor.
What happens when an intake manifold gasket goes bad?
A vacuum leak caused by a bad intake manifold gasket can throw off the engine’s air-fuel ratio and cause engine performance issues such as misfires, a decrease in power and acceleration, a reduction in fuel efficiency, and even stalling.
What to do if your intake manifold is clogged?
A clogged-up intake manifold might need to be removed and cleaned manually. In some cases, replacing the intake manifold might be a more sensible solution than cleaning it. There are many hidden areas inside the manifold that cannot be cleaned. Tuning valves are typically operated by electric or vacuum actuators.
Why does my car have a variable intake manifold?
For this reason, modern cars have variable intake manifolds where special tuning valves change the air flow through the manifold depending on the engine speed and power demand. Common problems with intake manifolds include vacuum, coolant or oil leaks, reduced flow due to carbon build-up and issues with the intake tuning valves.
How much does it cost to replace an intake manifold gasket?
Among the most commonly replaced parts, an intake manifold gasket could cost you over $600 in parts and labor. There are so many things that can go wrong with the manifold, especially if the gasket is compromised. This little gasket that sits between the engine and the intake manifold is supposed to be durable.
What should I do if my intake manifold is failing?
If you suspect that your intake manifold gasket or gaskets may be having an issue, have the vehicle inspected by a professional technician from YourMechanic to determine if the gasket should be replaced.

Which is more important a gasket or an intake manifold?
A gasket is basically a seal which goes in between various components of the engine. This seal can be made from metal, paper, rubber, or a combination of them. However, there is no gasket more important to the engine than the intake manifold gasket.
Can a bad intake manifold cause a coolant leak?
Coolant leaks. Another symptom of a faulty intake manifold gasket is coolant leaks. Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak.
