turbo ???
 

I cant hear my turbo whistle anymore at idle or normal driving, just a little when i get on it. Is my turbo worn out?? If so rebuild or replace??

have you checked your air filter?

cleaned it earlier today, K&N stock replacement (8 yrs. old), still can only hear it when I get on it.

check your intercooler boots and make sure there not leaking

Ok thanks Ill give them a look

if thats not it remove the intake and check the play in the compressor wheel. Some up and down is normal but in and out is not.

Also look and make sure the compressor wheel has not hit the cover.

intercooler boots looked ok. what is the Compressor wheel?

How many miles? You really need a set of guages. Have you noticed any blac smoke? How about change of performance? If your turbo all of a sudden stops working - you should be able to notice that right away.

When you take the pipe off.. its the wheel inside the turbine housing that compresses the intake air.

You just looked at them? Did you check the clamps with a wrench?
