Noise from Idle air control valve after dohc turbo install.

I noticed after my turbo install at idle the "Idle air control valve" has a hissing noise like a vaccum leak from it . It coming from the vent (cap looking thing). I was wondering if it bleeds off a certain amount of air??. The car idles fine. I dont want to have a vaccum leak .
