Find noise: Win case of beer: NOISE IS FIXED
I've searched Nasioc for "inlet noise" and "weird noise" and found a bunch of threads with what I think is the same noise but to no conclusions. To be honest it sounds like the ball bearings in the turbo are ****ed but I took it out and no shaft play and it spins nice and smoothly. The noise is coming from the turbo area (or so it seems.) This noise was not occurring until I did turbo inlet, catch can, new front (header) o2 sensor. I need to figure this out, if you find it I'll buy you a case of beer, your choice (under $30) Last edited by Jeffros Spec V; 12-10-2007 at 12:17 AM. |

Is the noise a whistle, grind, exhaust leak? What does it sound like? It only happens when you just blip the throttle in neutral? Does it make it while driving?

Turbo inlet? Is it a metal intake? If so You turbo will make a funny whistle whine noise when you blip the throttle. You here this now because your intake makes the sound reverberate(sp) or echo/amplify it.

I don't think it is the throw out bearing cause that would be if your clutch is depressed and you would prob hear a little chatter as well when you are sitting there. The stock intake hides all the different noises for people who aren't turbo enthusiasts and intake mods get rid of the refinement stock airboxes and pipes try to conceal.

Hmm, is it whistling? How is your idle? If you are getting a leak after your MAF sensor you will have a bad idle depending on how much air is getting through.

Well I threw P0102 and P0113 and went and checked out my MAF. The two screws that held the maf into my intake were loose and I guess air was getting around. I tightened them and that went away. I am however also getting a whistling that i'm not sure if the inlet makes it sound this way or something else. The noise is driving me freaking crazy though. |

I checked it out last night and gave him my diagnosis, hopefully I am wrong. Its not a whistle, its more or a metal shaking/scraping noise in my opinion.
