ENGINE DRIVEABILITY AND EMISSIONS 6E–55
Low or high spark plug installation torque or improper
seating can result in the spark plug running too hot and
can cause excessive center electrode wear. The plug
and the cylinder head seats must be in good contact for
proper heat transfer and spark plug cooling. Dirty or
damaged threads in the head or on the spark plug can
keep it from seating even though the proper torque is
applied. Once spark plugs are properly seated, tighten
them to the torque shown in the Specifications Table.
Low torque may result in poor contact of the seats due
to a loose spark plug. Over tightening may cause the
spark plug shell to be stretched and will result in poor
contact between the seats. In extreme cases, exhaust
blow-by and damage beyond simple gap wear may
occur.
Cracked or broken insulators may be the result of
improper installation, damage during spark plug re-
gapping, or heat shock to the insulator material. Upper
insulators can be broken when a poorly fitting tool is
used during installation or removal, when the spark plug
is hit from the outside, or is dropped on a hard surface.
Cracks in the upper insulator may be inside the shell
and not visible. Also, the breakage may not cause
problems until oil or moisture penetrates the crack later. A broken or cracked lower insulator tip (around the
center electrode) may result from damage during re-
gapping or from “heat shock” (spark plug suddenly
operating too hot).
• Damage during re-gapping can happen if the gapping tool is pushed against the center electrode or the
insulator around it, causing the insulator to crack.
When re-gapping a spark plug, make the adjustment
by bending only the ground side terminal, keeping the
tool clear of other parts.
• “Heat shock” breakage in the lower insulator tip generally occurs during several engine operating
conditions (high speeds or heavy loading) and may
be caused by over-advanced timing or low grade
fuels. Heat shock refers to a rapid increase in the tip
temperature that causes the insulator material to
crack.
Spark plugs with less than the recommended amount of
service can sometimes be cleaned and re-gapped, then

1 General Information
The HFV6 engine features a closed vee, deep skirt die cast aluminium cylinder block with cast iron cylinder liners,
internally balanced crankcase, full length water jackets and six bolt main bearing caps.
The cylinders are arranged in two banks of three with a 60 degree included angle between the two banks.
The right-hand bank of cylinders consists of number 1-3-5
cylinders and the left-hand bank of cylinders consists of
number 2-4-6.
The engine firing order is 1-2-3-4-5-6.
Each aluminium cylinder head is fitted with hardened valve
seats and four valves per cylinder: two intake and two
exhaust.
The valves are operated by two camshafts (DOHC) per
cylinder bank, one each for intake and exhaust valves.
The crankshaft is manufactured from forged steel. A reluctor
wheel is pressed in place onto the rear of the crankshaft for
the crankshaft position sensor.
The connecting rods are manufactured from powdered
metal and the rod cap is separated during the manufacturing
process using the fractured method. This creates a stronger,
visually seamless rod to cap union.

Definition of WARNING, CAUTION and NOTE Statements

Diagnosis and repair procedures in this Section contain both general and specific W ARNING, CAUTION and NOTE
statements. HOLDEN LTD is dedicated to the presentation of service information that helps the technician to diagnose
and repair the systems necessary for proper operation of the vehicle. Certain procedures may present a hazard to the
technician if they are not followed in the recommended manner. W ARNING, CAUTION and NOTE statements are
designed to help prevent these hazards from occurring, but not all hazards can be foreseen.
WARNING defined
A W ARNING statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in death or injury. A W ARNING statement alerts you to take necessary action or not to take a
prohibited action. If a W ARNING statement is ignored, the following consequences may occur:
• Death or injury to the technician or other personnel working on the vehicle,
• Death or injury to other people in or near the workplace area, and / or
• Death or injury to the driver / or passenger(s) of the vehicle or other people, if the vehicle has been improperly
repaired.
CAUTION defined
A CAUTION statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in damage to or destruction of equipment, or corruption of data. If a CAUTION statement is ignored,
the following consequences may occur:
• Damage to the vehicle,
• Unnecessary vehicle repairs or component replacement,
• Faulty operation or performance of any system or component being repaired,
• Damage to any system or components which depend on the proper operation of the system or component being
repaired,

Reinstall
1 Apply a liberal amount of commercially available
camshaft / lifter prelube or equivalent to the pivot
pocket (1), roller (2) and valve slot (3) areas of the
camshaft followers.
Figure 6A1 – 270
2 Place the rocker arm in position on the valve tip and stationary hydraulic lash adjuster (SHLA). The
rounded head end of the arm seats on the SHLA
while the flat end seats on the valve tip.
CAUTION
• The rocker arm (1) must be positioned
squarely on the valve tip so the full width
of the roller will completely contact the
camshaft lobe.
• If the rocker arms are being reused, they
must be reinstalled in their original
location.
3 Clean the camshaft journals and carriers with a clean, lint-free cloth.
4 Reinstall the camshafts, refer to 3.19 Camshaft.

Valve Margin Measurement Procedure
1 Measure the valve margin using an appropriate scale.
2 Refer to 5 Specifications for minimum valve margin and compare them to your measurements.
3 If the valve margins are beyond specification, replace the valves.
4 If the valve margins are within specification and do not require refacing, test the valve for seat
concentricity, refer to Valve-to-Seat Concentricity
Measurement Procedure in this Section.

Figure 6A1 – 294
Valve-to-Seat Concentricity Measurement Procedure
Checking the valve-to-seat concentricity determines whether the valve and seat are sealing correctly.
Measure the valve face and the valve seat to ensure correct valve sealing.
1 Coat the valve face lightly with blue dye (3).
2 Install the valve in the cylinder head.
3 Turn the valve against the seat with enough pressure to wear off the dye.
4 Remove the valve from the cylinder head.
5 Inspect the valve face.
NOTE
• If the valve face is concentric, providing a
correct seal, with the valve stem, a continuous
mark (1) will be made around the entire face (2).
• The wear mark must be at least 0.5 mm from
the margin of the valve. If the wear mark is too
close to the margin, the seat must be
reconditioned to move the contact area away
from the margin.
• If the face is not concentric with the stem, the
mark will not be continuous around the valve
face. The valve should be refaced or replaced
and the seat must be reconditioned, refer to
Valve and Seat Reconditioning Procedure in
this Section.
Figure 6A1 – 295
Valve and Seat Reconditioning Procedure
If the valve seat width, roundness or concentricity are beyond specifications, grind the seats in order to ensure correct
heat dissipation and prevent the build up of carbon on the seats.
If valve seat reconditioning is required, reface the valve face, unless a new valve is used.
