Weird Suction Noise

[evil1]

hi all

my car gets a bit weird sometimes.

my induction noise normally sounds like a shhhhhhhhhhhhhhhhhhhh

but i get days where it sounds like a high pitched whistle.

ive checked for leaks all over, it holds boost still

my bov is disconnected...sorta have a feeling that its leaking through that but i highly doubt it

any ideas?

its a on a r34 sedan auto turbo

Hey mate

Have you tried connecting the blow of valve back and seeing what it does then?

Leaks are a pain, it only takes the slightest spilt or something to cause a unwanted noise. Have you sprayed soapy water on certain places to check for the leaks?

Mine makes the whistling noise as well. I haven't started looking for leaks yet, will soon because the noise is getting really annoying. Whats weird about your noise is that you only get it sometimes...
