Intake Manifold Gasket Replacement Cost
On some vehicles, there can be an upper and a lower intake manifold gasket. In these cases, the estimate provided will be for the lower intake manifold gasket replacement, which also includes the upper gasket replacement.
An intake manifold gasket can be the source of a vacuum leak and/or engine coolant leak.
An intake gasket with a vacuum leak will often have a rough idle and engine misfires. This may turn on the Check Engine Light and set misfire and/or fuel mixture "out of range" trouble codes.
Some intake manifolds are made of plastic. They can become pitted and may need to be replaced along with the intake gaskets.
