My turbo i believe is making a metal on metal sound instead of boosting the way it should i was driving everything was fine and all of a sudden i get a metal on metal rubbing sound like something was being dragged on the concrete. And the is a whistling sound coming from under the chasis where my down pipe is any one have a idea whats wrong any help would be awsome i am scared my bearings are fried?

 

It could just be rubbing somewhere. Does it do it when you are turning and accelerating during turns: left, right?? Mine rubs when I make hard left turns as the motor is being shifted to the right.

 

No its when am driving straight and around 3 k rpm is when it gets really loud sounds like the bearings arent being lubricated or something :s

 

Anyone with any ideas? with my luck my turbo bearings are shot :S

 

Probably a loose bolt or something. Get under the car and check it out.

 

I drove it angain and when bost is suppose to hit and i let of i dont hear a Bov sound just the mechanical concrete dragging and the turbo is spinning really load as if its all crapped out

 

Can you edit your title? It says nothing about your problem.

Something like: "Scraping noise from turbo"

 

As I said check your bolts, specifically the ones holding the wastegate...

 

Ok ill check all my connections again today i am hoping that it will solve my problem
