Due to some questions about lowering boost levels on the turbo, I fought with the beast long enough to extract it from under the hood.  When attached to the exhaust manifold (cast iron) the (cast iron) housing of the turbo is pretty heavy, awkward, and generally unpleasant to remove.

Removing it, however, was much more pleasant than seeing the condition of the intake impeller.  Ugly.   The leading edges of the fan blades are supposed to be quite smooth and sharp, not broken and jagged.   This is a seriously abused turbo.  I plead innocence, but I must be responsible for some of the damage, in some way, as this doesn't just *happen*, something has to hit those fan blades.  I'm guessing oil buildup from the crankcase ventilation could have passed some sort of crud.  Odd, but possible.  A catch can is in my future.

It is at the turbo rebuild place now, I await an estimate of how much this carnage is going to cost.   It has been an expensive weekend working on the truck.  :(   On the plus side-  it is going to drive much better next week, so that's good news!  :)

For what its worth:  you can't pull the turbo housing off of an hd-t without pulling the exhaust manifold.  I tried.  It doesn't work.   There are two bolts that simply can not be reached.

Also, all of my manifold studs pulled out (except one), so I'll be reinstalling those.  Anyone with tips on how to seat them properly, please feel free to make suggestions.

I did get my injectors back today, they are lovely and clean and I'm very excited about installing them and starting up the motor to hear/feel the difference.  But it looks like I'll be waiting until my turbo comes back, ah, well...  if there is one thing that I have learned in Costa Rica, it is the importance of patience.
