12-1-22 DESCRIPTION AND OPERATION
The camshaft carrier and cylinder head assembly is attached to the cylinder block by twelve cylinder head retaining
bolts which pass through the camshaft carrier and the cylinder head to secure the assembly to the cylinder block.
CAUTION: The valve heads, tips of the injectors and glow plugs protrude below the face of the cylinder head
and will be damaged if the cylinder head is stored face down.
The camshaft is located between the cylinder head and the camshaft carrier, and the bearing journals are line bored
between the two components to form a matched pair.
CAUTION: Always fit plugs to open connections to prevent contamination.
The valve guides and valve seat inserts are sintered components which are interference fit to the cylinder head. The
cylinder head machining also provide the locations for the electronic unit injectors, glow plugs, hydraulic lash
adjusters, finger followers and low pressure fuel rail.
Cooling to the cylinder head is provided by coolant flow through a water jacket machined into the cylinder head.
Drillings through the block provide lubrication channels for pressurised oil supply to cylinder head components such
as the lash adjusters, finger followers, rocker arms and camshaft bearings.
A coolant outlet elbow is fitted to the front LH side of the cylinder head to allow flow of coolant from the cylinder head
back to the radiator. A metal gasket is used to seal the joint between the water outlet elbow and the cylinder head. A
coolant temperature sensor is located in a port in the side of the water outlet elbow for monitoring coolant temperature.
A stub pipe is connected at the front RH side of the cylinder block above the timing cover which connects a pipe to
supply oil to the vacuum pump. The timing chain tensioner adjuster is screwed in a thread in the cylinder head at a
location on the front RH side of the engine below the oil feed port for the vacuum pump.
An access hole for the camshaft gear is included at the front of the cylinder head which is sealed with a plastic plug
and rubber 'O'-ring. A press-fit core plug for the chain chest is located on the front face of the cylinder head.
A press-fit core plug for the cylinder head water jacket is located at the rear of the cylinder head and a threaded brass
plug for the water jacket is located on the LH side of the cylinder head beneath the exhaust manifold assembly.
