Check your turbo for shaft play.

Sounds just like the issue I am having, I have a squeal that happens wHEN I should hear the turbo spooling up. It is more of a shrill sound then squeal though it is definitely quite loud though. I have checked the turbo and can't find anything physically wrong with it. I have checked the oil lines yet. Im thinking it is my wastegate though I need to figure out how to check that. Anybody want an 01 quad cab short bed 133k for 9500? It has an airdog 100 and brand new tires. Oh and a small turbo issue and 0216 code for a year and a half now.

I was going to say its sound like a drive pressure leak somewhere on the manifold before the turbo... But you got it!
