1 General Information
With the following exceptions, MY 2004 VY and V2 Series V6 Engine Mechanical Service Information carries over from
MY 2003 VY and V2 Series vehicles. For information not contained within this Section, refer to Section 6A1, Engine
Mechanical – V6 Engine in the MY 2003 VY and V2 Series Service Information.
• Revised engine oil level checking procedure.
• New powder forged ‘cracked’ type connecting rods where introduced as a running change during August 2003.

2 General Description
2.1 Connecting Rods
Powder forged and cracked type connecting rods where
introduced into production as a running change during
August 2003. Illustration 6A1-1 shows the difference in the
early cast and machined type (A) and later powder forged
and cracked type (B) connecting rods.
NOTE
Other than the revised manufacturing process
and a revised connecting rod cap bolt torque
specification, all other specifications and
servicing procedures relating to the connecting
rods remain unchanged.
CAUTION
The early type connecting rods can be
replaced by the late type connecting rods.
However, to avoid confusion with having
different bolt torque values, when replacing
early type connecting rods with the late
type, it is recommended that the connecting
rods be replaced as an engine set.

3. Service Operation
3.1 Engine Oil Level Check
1 The engine must be at normal operating temperature (drive the vehicle for 15 minutes).
2 Park the vehicle on a level surface.
• Do not check the oil level for at least 10
minutes after the engine is switched-off.
This allows time for the oil to drain back
into the oil pan.
• A sloping surface will affect the accuracy
of the measurement.
3 Remove the dipstick and wipe clean.
4 Reinstall the dipstick. Ensure that it is fully seated. Leave for several seconds and remove slowly to avoid
smearing the oil (level): then hold the dipstick horizontally to prevent the oil (level) moving along the dipstick.
5 Observe the oil level where it passes over the centre
line of the dipstick.
NOTE
The following are easy guides for how much oil
to add:
• For Type I engine oil level dipstick (A), the
ADD to FULL mark area (C) represents 1.5
litres of oil.
• For Type II engine oil level dipstick (B), the
cross-hatch area (C) represents 1.5 litres of
oil.
6 If the level is lower than, or close to the ADD mark,
top-up the engine with enough oil to reach the FULL
mark.
Do not fill over the FULL mark.
7 Allow several minutes for the added oil to drain down
into the oil pan then recheck the oil level.
