Howard,
Because of the comment the dealership made "Dealer says its INSIDE the engine and a major expense in labor to change it", makes me wonder what engine you actually have, as in 2003, for a short while, both the 7.3L and the 6.0L were available.
This is all hypopthesis... and out my rearend, but..... I really am wondering.
Remember when he had low power, and black smoke? That is a possible symptom of stuck vanes on a 6.0L VGT turbo. Again, talking out my butt!
How about you get us the VIN# and get someone to run an OASIS on this thing, to see what has REALLY been done to it.
Anyway, problem at hand.
I am looking for a picture of the HPOP location for you on a 7.3L
This is the rear of a 7.3L Diesel, note turbo location, and "style" (6.0 is different, you likely do not have the wastegate however (little goldish motor looking thing with red hose coming off of it)

This is a view of the top of the engine, i have pointed out the HPOP, the ICP and a couple of other things.
Hope This helps!
