pcv valve

Hi...I have an 06 g35 coupe. There is a hissing sound coming from where my pcv valve is when the car is idling. Is it suppose to sound like that, or do i have an air leak or something?

You have a vacumn leak.Either the pcv valve is broken or the hose has a split or hole in it.

i bet if you had a vacuum leak you would notice for sure that the car would run rough, might even light up the CEL.

this sound is normal. I hear it all the time on many different Gs.
