Hello,

I am having a noise at part throttle. But when i put more gas on the pedal the noise disappear. I hear thet noise, it gose like uiiiiiiiii, only when i have a part thorttle. Some friend of mine tell me that the air valve ( I think he meant the BOV) is leaking or something like that.

Do one of you guys know what can be the problem of that?

Thanks!

 

i think its better to take a sound clip of the noise,
uiiiiiiiii doesnt really help identifyin the noise

 

with a noise like uiiiiiii ima go with turbo spool? if not that then a boost leak.

 

The turbo spool is OK. I think that it would be the boost leak.

What is the most common couse for boost leak? The hoses seems all right.

 

When the boost is small, the noise appear, when it is high, no noise... If this helps.

 

Do you have the stock y-pipe? they were famous for leaking. start checking the miles of rubber hoses for cracks and such.
