Parked in my garage on idle heard these engine noises. Are these normal or anything to worry about? Car runs fine with 48k miles, automatic transmission L99 stock with no baffles and CAI inc intake.

Bump. Anyone?

Well I've never owned an SS. I went from a V6 LFX to a ZL1 but that sounds like a pulley or bearing issue when your AC compressor is cyling. Just a guess though.

I listened to it and it does sound like an idler/tension pulley might be to blame, maybe even the AC clutch going bad..

I took a look again today and see that the harmonic balancer is wobbling a bit. I stuck my hand down to feel the bolt and it was not loose. Did some search through the forums and found some threads saying this is normal in these corvette engines? am I wrong? Anyhow, will take to the dealer to check it as soon as I can. Took it to a mon n pop shop and they quoted me $600 total, not sure if this is a good deal or not.

AC is not on. Could it be harmonic balancer wobble causing that? See video above

One of my friends has this "wobbling" issue with his 2011 Corvette GS, and when I checked with my tune shop who specializes is LS engines, had told me that the "stock" balancers have has an issue of coming apart and causing it to wobble like that. Not saying that is your issue, but we replaced his with a Fluiddamper unit and all is fine now, mine was replaced with a GM performance unit and is good, but I never had a wobble problem. Good luck.
