Hier zumindest eine Quelle, die besagt, dass schmalere Ketten verbaut wurden...
Smaller Pitch Timing Chain
The 2.8L V6 Turbo features a new timing chain with a smaller pitch (7.7 mm compared to 9.5mm previously) and more links. The chain applies an inverted tooth design. The smaller links engage at a lower impact speed, which decreases the noise generated. In conjunction with the new chain, the number of teeth on the sprockets is also increased, increasing the meshing frequency and further reducing noise and vibration.
Ergänzung:
The timing chains in the engine numbers listed below are prone to stretch. Don't let your Holden dealer tell you it's going to cost $3000+ to carry out the repair, it's a known design fault and was rectified in a manufacturing revision from -

Quote from Holden TL1551 – 0804
The 'beauty' of this fault is that it will usually present itself just out of the 3yr 100,000km warranty period. Suffice to say that statutory warranty exists for a reason and consumer affairs would probably be interested to hear from anyone who had to pay to have a manufacturing fault repaired on a vehicle that isn't even 5 years old yet. Holden customer assistance will organise a refund for anyone who has had to pay for this repair to be carried out in most cases.
