A cast and machined alloy fuel connector block assembly is located at the rear RH side of the cylinder head, attached by three flanged bolts. A metal gasket is used to seal the faces between the fuel connector block and the cylinder head, which must be replaced every time the fuel connector block is removed.

CAUTION: The cylinder head incorporates drillings for the fuel injection system, any contamination which enters these drillings could cause engine running problems or injector failure. It is therefore, essential that absolute cleanliness is maintained when carrying out work on the cylinder head.

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.

Camshaft carrier The cast aluminium alloy camshaft carrier is bolted to the cylinder head by thirteen screws. 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.

The carrier is machined together with the cylinder head to form a matched pair for carrying the camshaft.

Non-return valve A non-return valve is located at the front, bottom LH side of the cylinder head. The non-return valve prevents oil from draining from the lash adjusters and is an integral component within the cylinder head and is non-serviceable.
