so i went into boost today, and i heard this wierd krinkling sound. only when i went into boost, then after a few times it slowly stopped. WTF happened?

my girlfriend said "it sounds like the boost is creaky"

idk if she was serious. i dont think so.

did you notice anything different after you heard the noise?

only that it did it less and less every time i did it till it went away..wtf.

Try checking the wastegate and bov, maybe something loose.

Arthritis FTL.


IDK, possible carbon breaking loose, hitting the turbine? If it was the turbine wheel hitting something else, you prolly would have heard worse noises shortly thereafter. Not to mention a drastic loss of performance.

I'm not going to tell you not to worry, since it has gone away, because if it was my car/time/$, I would be a little bugged about it too.

Not saying there was anything done wrong, just those little gremlins that thrive on screwing with you.

Edit: After reading your other thread about running rich, it may have built up some carbon on the exhaust side of things. ?

good thought, thats actually what ithought 2. ill let it go if something breaks we will know
