a SECRET TSB I thought everyone should know about
I started noticing a rattle noise every now and then on my engine of the SS/SC about a month ago. Every time I let one of the guys here at work listen it wouldn't do it . It finally done it with them around. They called GM and they said there is a TSB on what has happened to my car.
We asked what's the number and we will look at it. The rep said that it is not available to the public. It's only available on a call in basis. So I thought I would make it available to the peeps here
Lucky me has to have the front of his engine torn apart for a better timing set.

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.

So this is different than the rattle of the supercharger after its been broken in? Because I hear a rattling noise coming from the engine once in a while, but have noticed no metal flakes in my oil.

That's exactly what was happening with mine. I would hear a noise, not all the time, coming from the engine compartment. It don't do it all the time. It's only when the engine is at operating temp and at an idle. You rev it up to past 2500 rpm's or so, then it goes away.
My build date was Sept 14, 2006. You might have the same issue later on.

Well WTF, my car was bought in May of 05 and I have that EXACT PROBLEM!!! In every way you describe it. Comes and goes. Goes away if you move or rev, only knocks at idle. Been happenging for awhile now, but I wonder if they won't check that TSB for me, since I'm not within the build dates specified?

The only way to check that TSB is for them to call GM themselves. GM is not goin to put that one on the site to be seen. It's only on a call-in basis.
Some of yall that might have this problem, just put your last 8 of your VIN on here and I should be able to tell the build date for ya to see if it falls within the dates specified.
