- Because of constant expansion and contraction from temperature changes, coolant and oil contamination, and the constant flow of intake air, the intake manifold gaskets can slowly break down and eventually get to the point where is deteriorates enough to cause a leak.

How often does an intake manifold need to be replaced?
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.
Is intake manifold gasket same as head gasket?
As previously mentioned, intake manifold gaskets are found between the intake manifold and the cylinder head, whereas head gaskets are found between the cylinder head and the engine block. When they blow, intake manifold gaskets and head gaskets will typically leak different substances.
What does a manifold leak sound like?
A leaking exhaust manifold will almost always create a ticking or tapping noise. Often, the sound is more pronounced upon startup when the engine and the manifold are both cold. The noise may diminish or disappear once the engine warms up and the manifold expands, closing off the leak.
What are the first signs of a blown head gasket?
