Pcv hose hiss
 

As the title says, does anyone else hear a constant hiss near the intake manifold and pcv hose? To me it sounds like the hiss goes all the way throughout the hose. Been trying to hunt down a vacuum leak with no luck ..
Have a 2009 Nissan 370z

Both of mine hiss too. I'm pretty sure its normal.

The PCV valve outlet is pretty small. I think that is what creates the hiss sound.

Normal, no issues.
