my car breathes?!?!?
 

just noticed something right after i turned the engined off. heard my car breath like a whale. what's wrong?

It was breathing a sigh of relief that the stress over the oil separator valve had died down?

Sorry, couldn't resist. Air suspension?

it's most likely the oil separator?

No. My comment was that after all your stress over your oil separator, the car was simply breathing a sigh of relief. Joke. :stickpoke

More likely to be air suspension.

jcl are you sure? i hear the sound from the hood.

do you have an open element air filter? i have an afe kit in mine and i hear it "exhale" sometimes when i turn off the ignition

yeah. there are a few that won't close.

I hear mine do this everytime I turn it off. I figured it was normal, nobody else has this? It's kind of a hiss of air coming from what I assume is some emissions control device...

that noise is normal on 6cyl, it is releasing the vaccum left inside the oil separator. if the engine did not make this noise, then the diagphram has failed.

Had the car now for about 2months...and I ALWAYS hear it too right after turning ignition off. Good to know it's normal!
