I've done mine, with out removing the turbo. Its just that the Banjo bolt is one of those 45 minute bolts. Also it helps to have grease and diesel fuel on your hands so they can slide around so you can start the banjo bolt. I think Baz has a write up on his site on how to do it step by step.
Its not too bad. It was the first major thing I did to my truck and never having a diesel before I was right stoked that I did it.
Took about 6 hours...
Only thing happend was a small hose clamp fell into the hole where the tappet goes, down into the bowels of the engine... its still there.
Check out my post on the "other site" from about 2 years ago.
Its kinda of funny now, but at the time, I was sh*&* my pants...
