Resolved need help identifying strange peeping sound

[2gEclips3]

Whenever i take my car for a spin, it doesnt mather if the engine is cold or warm, its starts "peeping" when i take my foot of the gas pedal. It doesnt happen when my car stands still nor any given rate of rpm, it does it all the time. It shuts up when i press down the gas pedal again. I didnt take it as a problem at first, but its getting worse/louder. Sometimes the sound disappears when i press down the clutch aswell. Any ideas?

You must be logged in to view this image or video.

hopefully this link works. you can hear the sound very clearly 30 seconds in, lasting nearly 10 seconds

It kind of sounds like the bov pulling in air. Is it vented?

 

[tay97gst]

I would agree it's probably the BOV, I have a crushed 1g and it makes similar sounds while engine breaking.

Yes, its a vta bov. Is it that simple, and why does it suck air? Im going to change the bov next year to Forge with recirculation, you think that sound will disappear then?

Are you still running a maf? If so you should recirculate the bov back to intake tube. If not are you running SD and link to control the air measured.

still got the maf unit on. dont think im going to get rid of it at first either. if im getting rid of the maf, i need a EMS system or something? tuning? i cant recirculate the bov i got atm, but my next investment will be a new bov

 

[Type1DSMr]

Yes get another bov soon. More than likely that's your problem and more. You can get a 1g bov pretty cheap on classifieds just need adapter for 2g intercooler pipe.

But will this do any harm to my engine? thats my main concern.

 

[Type1DSMr]

Yes, that's why you should recirculate ASAP without the proper setup for vented bov.
