Cylinder head JAGUAR XFR 2010 1.G User Guide

Prior to having the cylinder head machined, prior approval is
required by Jaguar or Land Rover engineering.


If the cylinder head requires machining, this must be carried out by
a local engineering company.

If the cylinder head exceeds the maximum value (0.2mm), the cylinder
head must be machined.

CYLINDER BLOCK Component Description



The cylinder block is a 90 degree configuration with cast-in iron cylinder liners and an open deck die-cast coolant jacket. The
low volume coolant jacket gives good warm-up times and low piston noise levels. The longitudinal flow design of the coolant
jacket, with a single cylinder head coolant transfer port in each bank, provides good rigidity and head gasket sealing.

NOTE: RH (right-hand) (A bank) cylinder head shown, LH (left-hand) (B bank) cylinder head similar.

1 Cylinder head 2 Gasket 3 Heat shield 4 Gasket 5 Exhaust manifold 6 Bolt (8 off) 7 Heat shield 8 Bolt (4 off) 9 Spacer (8 off) The high SiMo (silicon molybdenum) cast iron exhaust manifolds are unique for each cylinder bank. Each exhaust manifold
installation includes two metal gaskets and two heat shields. Spacers on the securing bolts allow the manifolds to expand and
contract with changes of temperature while maintaining the clamping loads. NOTE: LH (B bank) installation shown, RH (A bank) installation similar.

1 Inlet camshafts 2 Exhaust camshaft 3 Inverted tooth timing chain 4 Nylon chain guide 5 Auxiliary chain tensioner 6 Auxiliary drive chain 7 Oil pump drive 8 Auxiliary drive camshaft 9 Timing chain tensioner 10 Tensioner lever 11 VCT unit 12 VCT solenoids The lightweight valve train provides good economy and noise levels and is chain driven from the crankshaft.

Double overhead camshafts on each cylinder head operate the valves. For each cylinder head, an inverted tooth timing chain
transfers drive from the crankshaft to the VCT (variable camshaft timing) unit on the front of each camshaft. Graded tappets
enable setting of inlet and exhaust valve clearances.

Each timing chain has a hydraulic tensioner operated by engine oil pressure. The chain tensioners incorporate a ratchet
mechanism, which maintains tension while the engine is stopped to eliminate start-up noise. The chains are lubricated with
engine oil from jets located at the front of the engine block. Nylon chain guides control chain motion on the drive side. VALVE TRAIN

16 Bias spring 17 Snap ring 18 Reluctor ring 19 Center plate 20 Snap ring 21 Screw (6 off) 22 Spool valve 23 Outer plate Each VCT unit is attached to the camshaft by three bolts. A rotor assembly and a reed plate are installed inside a sprocket housing, which consists of a sprocket, an outer plate and an inner plate held together by six screws.

A reluctor ring, for the CMP (camshaft position) sensor, a center plate and a bias spring are installed at the front of the VCT unit. The ends of the bias spring locate on the center plate assembly and the sprocket housing, to give a turning moment to
the camshaft in the advance direction. A snap ring locates the reluctor ring on to a sleeve installed in the center of the rotor
assembly. The opposite end of the sleeve locates in a bore in the front face of the camshaft, which contains a filter.

A spring and spool valve are installed in the rotor assembly sleeve and retained by a snap ring. The spring keeps the spool
valve in contact with the armature of the related VCT solenoid.
Each VCT unit is supplied with engine oil from an oil gallery in the cylinder head, through the camshaft front bearing cap and a bore in the center of the camshaft.
Variable Camshaft Timing Solenoids
The VCT solenoids control the position of the spool valves in the VCT units.


The VCT solenoids are installed in the front upper timing covers, immediately in front of their related VCT units. Each VCT solenoid is secured with two screws and sealed with an O-ring. A two pin electrical connector provides the interface with the
engine harness.

Each VCT solenoid incorporates a spindle that acts on the spool valve in the related VCT unit to advance and retard the camshaft timing. The VCT solenoids operate independently and are controlled by a PWM signal from the ECM. www.JagDocs.com

1 Oil pump outlet tube 2 Anti-drain valve 3 Oil cooler 4 Oil filter 5 Piston cooling jets 6 Timing chain lubrication jets 7 Oil evacuation tube 8 Oil pump 9 Oil temperature and level sensor 10 Oil pick-up The oil pump is attached to the underside of the windage tray. The input shaft of the oil pump is driven from the front of the
crankshaft, by the auxiliary chain, at 0.87 engine speed.

The oil pump draws oil from the sump pan through a centrally mounted pick-up pipe. The oil is pressurized and pumped
through an output tube to the cylinder block. After passing through an anti-drain valve and a plate type oil cooler, the oil is
filtered by a replaceable cartridge installed on the front of the RH cylinder head. LUBRICATION SYSTEM
