Weird noise from engine bay

Hey all,

Benn hearing a noise from the engine bay & the best way to describe it is that it sounds like an air leak..

It doesn't sound like the type of noise I'd expect from an air filter.. but I did just replace the filter element in my in take pod so I guess it could just be flowing better than ever now & I'm just starting to hear what it *should* sound like. ..

problem is though, it doesn't sound like its sucking air in, definitely sounds like air going out..

any ideas?

A puncture

No seriously when does it happen?
At idle? or when accellerating? or on decel?

Doesn't happen on idle, just when accelerating, it's louder when I put my foot down, but .. seems to do it more when it's really hot because I drove home at about 10 pm last night & it was cooler & it didn't happen at all, even when revving to max.

today, it happen pretty much the whole way home but it was a scorcher today..

I suspected a bad connection between the intake & Throttle body, but I've disconnected & re-joined it a couple of times now..

been told it could be a leaking vacuum hose..

Update:

Issue only occurs while I have the air conditioning on.

Doesn't happen if just running fans, or the aircon is off.

Hence why it was only happening when it was really hot out & not at night

(not running aircon at night)

I can't seem to pinpoint where the noise is coming from though..

I'll keep at it.. but if anyone has any ideas, let me know ..
