Intake whistling sound When I put my longtubes on a couple months ago I deleted my AIR system, and I've noticed that sometimes it makes a whistling sound that's very audible when the windows are closed.
When I deleted the AIR system I left in the valve-looking think that the hoses connected to since the instructions I was using didn't mention it. When I put on my LS6 IM a month later I realized that it had a vacuum tube attached to it that ran to the back of the IM. So it appears that unfiltered air is being sucked into the IM, which is of course bad.
So my question is, can I just unhook that little hose and RTV it shut, and will that kill my whistling sound? Also, can I take the valve thing out? It's attached to an electrical cable, so will that just throw more AIR codes if I pull it out (I'm deleting the codes once I order a copy of HPTuners)?

Well I guess I should be asking if it would harm the engine to block the tube somehow, or if I even should worry about the open tube at all. I don't want some goofy vacuum problem to occur.

Welp,
I had the PCV hose leak that Kelly mentioned, and it whistled like crazy and made the idle wierd. It also set off my SES light with too lean of a signal, since the air was coming in downstream of the MAF. You might wanna take that into consideration with your whistler, too. If it's on the back of the intake, I think that goes to your MAP sensor.
