How long do intake manifold gaskets last?
around 50,000 to 75,000 miles
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.Jan 14, 2016

Can intake manifold leak cause white smoke?
A leaking intake manifold gasket can cause white smoke from the exhaust, if the engine has coolant flowing through the intake manifold. A dry intake manifold will not cause this symptom.
Does coolant go through intake manifold?
The intake manifold also helps cool down the cylinders to prevent the engine from overheating. Coolant runs through the manifold to the cylinder heads where the coolant absorbs the heat and reduces engine temperature.
