Engine Serial Number

The engine serial number is located on the machined pad
(1) at the left-hand rear of the cylinder block.

The following is a breakdown of the engine serial number,
using an example of 10H7E H051230001:
•

10 = Component ID (i.e. 10 = Assembly)

•

H7E = Engine Broadcast Code

•

H = Assembly Plant Code

•

05 = Build Year

•

123 = Julian Date

•

0001 = Four Digit Daily Sequence Number

Construction

Cylinder Block

The cylinder block (1) is constructed from aluminium alloy
with cast-in-place iron cylinder bore liners.

Each of the four copper-infiltrated sintered steel main
bearing caps are attached to the cylinder block by six bolts.
Along with two outer and two inner bolts, two side bolts are
used in the deep skirt block for increased block stiffness.

The crankshaft thrust bearing is mounted in the third main
bearing cap.

To prevent aeration, oil return from the valve train and
cylinder heads is channelled away from the reciprocating
components through oil drain back passages incorporated
into the cylinder heads and engine block. Pressure
actuated piston oil cooling jets are mounted between
opposing cylinders.

Figure 6A1 – 14

Cylinder Heads

The cylinder heads (1) are semi-permanent mould cast
aluminium with powdered metal valve seat inserts and
valve guides.

Figure 6A1 – 15

Each cylinder head contains four valves per cylinder. The
valves (1) are actuated by the rocker arms (2) that pivot on
stationary hydraulic lash adjusters (3), which are oil-fed to
maintain valve / rocker lash.

The separate exhaust and intake camshafts are supported
by four bearings machined into the cylinder head. The front
camshaft bearing cap is used as a thrust control surface for
each camshaft.

A tube (4) is pressed into each cylinder head in three
places that shields each spark plug. An ignition coil
assembly is mounted directly on each spark plug, through
each spark plug tube.
