someone posted in another thread.

This is an actual copy of the TSB that was sent from GMTAC. Like I said on
another post, dealers WILL NOT find this on GMDealerworld. It's not available
to dealers online. It's only available through GMTAC. The tech has to call GM
with a repair order number and VIN number and mention the problems. Then if
they get someone that knows anything they will fax the below TSB to the tech.

Hope it helps.

The AIP number below is the only reference to the TSB.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s)
described in this PI.

CONDITION/CONCERN:

On rare occasions, a tick or rattle noise may be heard from behind the front cover
of the engine and/or pieces of a timing chain roller may be found during an oil change.
This may be the result of a timing chain concern.

Non-heat treated timing chain rollers were randomly installed in the assembly line hoppers.
He advised that this happened sometime between 4/1/06 - 11/1/06 so it can randomly affect
late 2006 - early 2007 models.

RECOMMENDATION/INSTRUCTIONS:

If this concern is experienced, inspect the timing chain for missing or damaged timing
chain rollers. If a missing or damaged timing chain roller is found, replace the timing
chain and gears using the part numbers currently listed in the parts catalog.

Please follow this diagnostic or repair process thoroughly and complete each step.
If the condition exhibited is resolved without completing every step, the remaining
steps do not need to be performed.
