Anyone know what this "whistling" sound is coming from the engine bay? I hear this from older cars every so often...but not sure why I suddenly hear it coming from this 2007 Corvette Z06 with 20k miles.

its your intake system. the ls7 does not have a silencer on the intake system like the LS3

The Vararam does a major whister sounds air the r's go up sucking air. Very noticeable. The good news is it assures you got a nice tight air intake & no vacuum leaks. Unless at idle then it may be a leak.

i just replaced my alternator because it had a whine, just like that. It wasn't affecting anything, but I just couldn't stand the sound. It started as quiet and barely noticable, and then it got progressively louder. Got a new alternator on and the car engine bay no longer whistles, I love my car again!

Seen a couple of posts where folks had that alternator issue. I'll see about getting it replaced. Thanks for the replies!

...or it could be ur alternator. Nothing worse than arm charm misdiagnosis or bad advice. At least it was free.
