was your screech like a hamster running in its wheel? I have a noise under boost, early in the boost that sounds like a metal hamster wheel running. I can't seem to record it well enough.

Mine sounded more like a slipping fan belt..a noise I still can't believe an exhaust leak made....but did
I don't imagine every one of them will sound the same.
I'd be really surprised if more don't have exhaust manifold leaks due to the bolt pattern of the manifold.
In the area it was leaking(lower rear end pointing towards cab) the 5 bolt pattern leaves a fairly large area of no support.
Basically from what I remember the bolt patern goes a bolt up and down on front and middle of manifold,but only top on rear.
Even the shop foreman at dealership thought it was a weak point.
