## 🔌 Function

The inlet manifold channels charge air from the turbocharger and charge air cooler into the cylinder head intake ports, distributing it evenly across all cylinders. A correctly sealed manifold maintains boost pressure and supports clean, efficient combustion.

## ⚠️ Common Signs of Failure

-   Audible air leaks or whistling under boost from cracked castings or failed gasket faces
-   Loss of boost pressure with reduced power and increased exhaust smoke
-   Corrosion, pitting or oil and soot residue around the manifold mating flanges
-   Warped or damaged sealing surfaces preventing a proper gasket seal
-   Cracking around mounting bosses or stud holes from thermal cycling and over-torqued fasteners

## 🛠️ Service Notes

-   Blank the open ports as soon as the manifold is off, so nothing can drop into a cylinder or the head while it is away
-   Clean both mating faces without scoring them, check the manifold for flatness, cracks and corrosion, and fit new gaskets and seals throughout
-   Clean out oil, soot and carbon deposits from the manifold interior before refitting, and look at the crankcase breather arrangement if the build-up is heavy — refitting a fouled manifold puts the restriction straight back
-   Tighten the fasteners evenly, working outwards from the centre in stages to the figures given in the workshop manual for your engine
-   Refit and check all charge air, breather and sensor connections and their clips; an air leak on a pressure-charged inlet shows up as lost power and smoke rather than an audible leak
