Ask your tuner to check it out for you. He might be able to help

 

Here, like this. Its pretty easy to record. You can't hear mine super clearly but at right around 8 seconds is when it does it. It doesn't usually last longer than 1 second when mine does it but it does happen once every couple dozen starts or so, especially after it rains and/or is cold...

 

I've got 101k on mine and been tuned (CCSS3) since 80k, No trouble here, at all. I hit red line at least 3 times a day.

Of course that is on a 2009 RY Sedan.

 

They are coming into contact, just ever so slightly. But enough to leave marks.

My turbo is making the "blades hitting the housing" sound, but I am under warranty and gm is refusing to change the turbo until it blows up. I hope the blown impeller parts will take out the motor when they will be blown into pieces @ full boost...

 

now that is funny right there^^^lol

 

shaft play at 52k miles.

 

I had 89000 on my cobalt and my turbo was still working fine

 

bought my car at 67k now have 77k and no issues. When I get back to TN Wednesday (1600 mile road trip FTL) i'll check it out and snap a picture of mine, I'd be curious to see if I have any wear/play...

 

My turbo loves me, it puts in work and hasn't ever complained

 

this @ 51k, but the E-brake and the lights behind the buttons on the steering wheel..not so much

 

im at 71k and mine works great. been tuned since 63k @ 24psi

 

Im at 59k been tuned since 20k still on stock clutch and turbo. I try not to beat the **** out of my car though

 

Going to smile big when my turbo goes, just means i'm getting a bigger one. 73k miles going strong :-(

 

Have any of you even checked if you have shaft play though?
My turbo still seems to work fine at 52k miles, but i have been tuned since 36k miles.

 

I checked mine last week when I relubed my BPV.
