Thoughts on engine sound?

Hey all, I’m new so I’m sorry if this is a bad post or if I shouldn’t have posted it! I’ve been in the market for a C5 for a while and finally have found one that seems to meet all the boxes I’m looking for. I just wanted to get an experts opinion on the whistle sound that is in the engine bay, is this an alternator, pulley, headers, or an intake? Or is this something else I haven’t thought about? Thank you so much for your time!

Since it appears you do not have the tools or knowledge to sort out the problem, I suggest taking it to a recommended Corvette mechanic for a diagnosis (the local corvette club can give recommendations). JMHO.

Sounds like the air injection to me. Runs a minute or two on startup, then shuts off. If it doesn't shut off after a couple of minutes, I could be wrong or it could be an air injection issue.

Sounds like that might be it.

OP, do you still have your EGR system in-tact?

"A.I.R". no EGR on a C5.

Yes, I always get the use of the acronyms confused 😆

Agree. Runs for 240 seconds after start up.
