O.K. first I must say sorry to okfordteck for calling him a troll...I guess you could be both a tech and troll but that does not seem to be the case.I want to know;
is this just 05?
what are the symptoms too look for?
Do trucks with melted pistons have bad head gaskets too?(might make sense.)
You said perhaps leaky injectors and other say fords cut off is 5%fuel in the oil, perhaps a new cut off is in order?
I am sure others have better quesions but I would like too prevent this if it is in my controll.. the list...

Interesting for me is the history or discovery channal, this is down right neurotic... ok ford docs set me straight..
I thought the whole reason we diesel people have egt gauges was to prevent piston and turbo melting??? Is this still the preventative action monitering and keeping egt's in check??? Or can 3 & 5 just spontaneously combust??? Lack of power with elevated egts would deffinately worry me..Iam guessing one or two cylinders could be hyperthermic and not elevate all gas temperature. What side is 3 & 5 (left) and would that be the side to put the probe??? should be more sensitive to the problem??
Thanks in advance,
