turbo noise

Hey Guys,

I have a 2003 6.0l did a rebuild on it. Got it all back together runs ok, but the turbo is making noise. I can unplug the actuator and the noise stops. How can I check the actuator. now the noise is of course when it is running.. but unplugged the noise stops. Any ideas for me to check..

Thanks for any help..

Can you describe the noise a little better? Like a louder whistle?

Did you clean the turbo when you did the rebuild?

I ve heard of case that the vanes wear and rub cuasing them to screch. so you need a way of testing for that was well.

sounds like the compressor wheel is rubbing, like a high pitch metal screeching like a drill press drilling into some metal, and it sounds gritty like a bearing is shot. I can hear it through the rpm ranges and it gives me a headache. Is yours the same way?
