V6 noise from intake manifold area

[nextstep]

Hi All,

I noticed a hissing sound from the center of intake manifold area. It almost feels like a vacuum leak. Don't seem to be happening when the engine is cold. Is anyone else hearing this? It is more noticeable if you stand on drivers side.

Thanks,
Renato

Mine actually does that too, its more noticeable while idle and revving, the intake manifold part makes a weird vacuum suction noise every time I rev, dunno whats going on :shrug:

Were you able to figure anything out?

Nothing yet. I'll probably go see the dealer but I was hoping someone on the forum would share information. Maybe it's normal?!
