Key Information

The preheater manifold gasket is a critical seal for the engine's intake system. It is positioned between the air intake manifold and the preheater unit (often used to warm incoming air during cold starts). Its primary function is to provide an airtight, pressure-resistant seal that prevents vacuum leaks or "boost air" loss from the turbocharger system. Maintaining this seal is essential for ensuring efficient combustion and proper engine performance, as leaks in this area can lead to power loss, increased fuel consumption, and fault codes related to manifold pressure.
