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

1.4 Engine 

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.
