Found this online. I figure it is old news to every one here. Looks like after 06 they got most of the bugs worked out. Too bad ours was a 05.. Was a great truck when it ran...
[edit] 6.0
Unable to meet strict emissions regulations, the 7.3L (445 cu in) Power Stroke was replaced by the 6.0 L (366.1 cu in) during the 2003 year model. This version lasted through 2008 (2007 model year). Many 6.0 L Power Stroke engines proved unreliable,[1] may have cost Ford hundreds of millions of dollars in warranty repairs and leading to a recall and repurchase of at least 500 trucks. The major problem with the Navistar diesel engines is damage resulting from defective fuel injectors, which suffer from side loading, which then causes raw fuel to flood and enter the engine's oil crankcase or hydro-lock the engine. The former occurrence is so disastrous that a total engine replacement has been required in some cases. There were also minor problems resulting from the unreliable factory variable-vane turbocharger, head gasket problems, EGR valve carbon deposit clogging/sticking, defective Exhaust Pressure (EP) sensor/connector, extensive PCM recalibrations, fuel injector harness chafing/crushing, general engine stalling/bucking, and inability to conform to the new Federal diesel emissions standards of January 1, 2007. There were many running changes to the engine and in the 2006 year model the 6.0 had the lowest rate of warranty claims across the board for Ford motor company when compared to all of Ford's gas and diesel engines.
The engine had an 3.74 in (95 mm) bore and 4.13 in (104.9 mm) stroke for a displacement of 365 cu in (6 L) or 5954 CC. It utilized a turbocharger and intercooler, producing 325 hp (242 kW) and 570 lb·ft (773 N·m) with an 18:1 compression ratio, redlining at 4500 rpm.
This engine is still being utilized in the E-series until the end of the 2009 calendar year. The engine is the same configuration as the 2007 YM with a diesel particulate filter added to the exhaust system.
