What's the diagnosis on the engine? I mean, I recall you said a part died,
but was any serious damage done? And why did the part fail on a new truck?

According to the diesel techs, certain 2005 Ford Powerstoke engines had a
problem with the design and machining of the "High Pressure Oil Pump". This
device, controlled by a computer (of course) is used to pulse the fuel
injectors to squirt fuel into the cylinders. The series of faulty pumps
destroy themselves over time - in my case, 8000 miles- and the engine stops
running. No recall was issued - just a technical service bulletin (TSB) for
techs to check for a potential problem during routine service. Apparently,
the tech who last serviced my truck didn't read the TSB. To make matters
worse, the HP pump was considered to be so reliable that the manufacturer
who makes the engines for Ford (International) buried the pump deep inside
the engine so they have to take it half apart to replace the pump.

The good news is that the replacement pump has been redesigned to correct
the errors of the original and it should last the lifetime of the engine,
whatever that is.
