Thankyou, Thankyou, Thankyou!
I have been having this chirp noise for weeks/months now, sometimes for only a few minutes, but now nearly continuous.
I had replaced the idler and tensioner bearings (x3) as was told this could be the problem, but NO.
Then after taking it in a our WOF (Warrant of Fitness) here in New Zealand, and mentioning the chirp, my tech looked at it, and said the Harmonic Balancer was wobbling. A bit of research and all was pointing to the HB.
Reading everyone comments, I am now ready to order a replacement HB and bolt, and might as well also order the seal.
Now, as I am not in the US, and we have limited access to local suppliers for these parts, could someone recommend the best (or better) place to order the parts, and the recommendation on what to get?
I do intend to do some work on the motor at some stage to bring the HP up, so I don't mind spending a little more if needed. I see that some do recommend the Powerbond HB.
Any further suggestions, would be most grateful, need to do this right first time.
Thanks Kevin

Fwiw.. I had my GM world class tech install the summit racing harmonic balancer yesterday. I think it was around six or seven hours labor with removing the steering rack.
I have to say I think the car is running smoother than before as I go up through the rev range.
He didn't use the ARP bolt and he said stock was fine.
Mines a 2008 c6 z51 manual. I'm glad I changed the harmonic balancer. I know it sounds nuts but the engine revs smoother ...and I believe since having this installed the knock sensors might have been pulling some timing before the swap yesterday.
I could be wrong and it could all be in my imagination but that's my initial impression fwiw...
Just a heads up. I think swapping out the harmonic balancer for the summit racing one was a good move on my part. I enjoy driving my car just a little bit more since it seems to be running smoother as I hammer the throttle..
(Edit) I put 119546 miles since new on this car. Still on the original clutch too...lol
What a great car!

Powerbond is said to be better quality, longer life, more reliable than oem.
it hits the sweet spot in value, providing great service at lower cost than other options. Others might be marginally better, but for 2x or 3x the $$. The extra costs, in my mind, are justified only if you are building for huge HP.
I went with upgraded ARP bolt. Going from memory, it was $10-$15.

As far as the chirping, I thought it was my HB, too, but it wasn't. The chirping was coming from my a/c idler and tensioner pulleys. Get two of these:

Thank you for all for your input Scottunger. Questions I'm still trying to track down my chirping noise and I know it's not from serpentine belt idler pulley or serpentine belt tensioner pulley. If i need to replace the ac belt tensioner pulley, can i buy the ac idler pulley and just use the ac idler pulley mount on the ac belt tensior pulley? so I don't have to buy the ac belt tensioer pulley as assembly w/pulley to save cost?
