Inlet Manifold Gasket replacement & repair made easy

The inlet manifold gasket is sandwiched in between the engine and the air intake manifold and seals the two components together. It is usually made of a metal or hard composite material and has sections cut out to reflect the area where air flows through it.

The air / fuel mixture flows from the air inlets on the manifold into the engine to be combusted in the engine's cylinder. Additionally, the inlet manifold also serves as a cooling device for the engine coolant which flows through it (and therefore also through the gasket).

An inlet manifold gasket replacement typically takes around 1.5 hours, but can take less or more time. Ultimately, the time that the job will take depends on a range of factors. For example, your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.

Due to the extreme temperature fluctuations inside the engine (during the combustion cycles the engine cools and heats continuously) the inlet manifold gasket is especially prone to wear and should always be replaced as and when stipulated in the guidelines set out by your car's manufacturer.

It is important to ensure that the gasket is in a good condition as a damaged gasket can cause engine coolant to leak out, risking overheating of the engine. Therefore, should you experience problems with the gasket, then it is important to have the manifold's gasket inspected and, if necessary, have it replaced.

If you suspect there is any issue with your vehicle's intake manifold gasket or there are concerns about its age or condition, book an inspection with a professional mechanic with immediate effect, driving the vehicle may lead to further complications and damage.
