Turbo Whistling

[SiR_RB]

mine does this too but not when making boost, if i cruise in 4th or 5th and slowly accelerate it will make a whistle sound, if i hold the accerator still it will continue to whistle, soon as i just move the pedal, it will stop, all while in negative boost

i tried tightening the turbo to manifold bolts but could only access 3, and they were loose, the one i couldnt get to was the bottom left one, there was an oil feed line inthe way so i didnt want to muck around with undoing it etc

how hard is it to access the exhaust manifold bolts? i think thats my problem, i went to unscrew the heatshield and one of the bolts snapped that holds it in place...i gave up straight after that happened LOL

Hi, ive just started to hear a whistling sound, or almost a really high pitched ZZZZZZZZZ noise coming from somewhere though not that loud.. yet, hopefully one of the turbo gaskets/manifold joins or something simple.

Anyway i was interested, when you say you got it rebuilt, did you get your stock turbo "highflowed"? if so what is the deal, do they replace it with steel turbines and was it expensive? cheers.

you could have split gaskets, which wont be fixed by just tightening the bolts and nuts.

When i took me turbo out, I noticed that my exh mani gasket was in 3 pieces.

Its not too hard to take the turbo off really.
