I was coming home from a road trip tonight. We stopped in to grab a bite, and when we got back out on the road the turbo started making a little screeching noise. I heard it and first thought it was a idler pulley or something. I stopped in the next little town and the screeching had gotten worse. It was very loud even when I was just sitting in park. I unplugged the VGT wire and it quit doing it, so I limped on home. Do you think I need a turbo or could it be something else?? I have the egr blocked with the welded up flex pipe so I hope that could be it instead of the turbo. I will check that in the morning. I still build good boost, it just sounds like the turbo is about to come apart. Thanks Guys!!

Sounds like if anything it's on its way out. Id start pricing a turbo just in case.

check all your boots, check your egr delete thing. check your up pipes, y pipe.

if your turbo was grinding, screeching it wouldnt have lasted that long and wouldnt have made boost

I just went out and took my intake off of my turbo and it was spinning freely and didn't have any play in it. I got under it and felt up around the downpipe and up-pipe and felt a little bit of wind coming from up around the up-pipe somewhere!

If the turbo spins freely and has no play does that mean the turbo is probably ok??

theres nothing wrong with that turbo.

its in the up pipe or y pipe. you need to look for cracked bellows or something like that

here is a picture to show a bad y pipe. last picture shows the bellow removed
