My R32 GTR seems to have some sort of vacumm leak, it's very spiratic, symptoms are:
- when starting the car when it's cold it will start making a high pitched noise, i can stop it by blipping the throttle
- after i giver a little on the highway it makes the same noise and i can again stop it by blipping the throttle
- when i'm anywhere above 0 boost you can hear a whirring noise which I never heard when I first got the car. It's not your normal turbo spool noise, it's much louder. I've even gotten some comments from people driving next to me thinking I have a huge single turboed car. Although it's not nearly as 'high-pitched' like as the 2 points above.
I'm not sure if it's the turbo or something to do with the engine, because you can hear it when I'm not boosting but then it sounds not nearly as bad when I'm on boost. Very confused here, any help would be great!
Thanks.
