LR3/Disco 3
The exhaust manifolds are cast from steel alloy and are unique for each cylinder bank. They are sealed to the cylinder
head by means of a steel gasket. Sacrificial plastic sleeves are used to align the manifolds. These sleeves must be
changed when refitting the manifolds. Spacers on the securing bolts allow the manifolds to expand and retract with
changes of temperature while maintaining the clamping loads.
Each manifold has a connection for the EGR transfer pipe.
The engine is fitted with a Variable Geometry Turbocharger (VGT), which is fixed to the exhaust manifold by a three hole
flange with a steel gasket.
Crossover Pipe
A crossover pipe carries the exhaust gasses from the RH exhaust manifold to the turbocharger on the LH exhaust
manifold. The crossover pipe is located at the rear of the engine and is routed across the top of the transmissions bell
housing.
