Air leak sound on engine?

[adamgl]

I'm hearing a sound come from the drivers side of the air intake manifold / fuel rail area. (Boxed in area on pic). It sounds just like an air leak in a shop air hose. A steady pssssshhh sound at idle. Can anyone else hear the same sound from that area on their car? I can't find anything causing the sound. I only hear it from that one specific area.

Any ideas on what is causing this?

I have a K&N cold air intake kit and American Racing Headers on my car.

Thanks for any help.

It could be the PCV line at the rear valve cover area. If you can find a section of 2ft hose (like 3/4 radiator hose) to use as a sound isolator it may help. One end to your ear the other at suspected areas. Old school, I know, but sometimes it works.

Old school, yes, but works everytime I have to try and find a hard to pinpoint noise.
