Good advice. I am going to see how this repair works out because
otherwise I like the truck very much. I agree with all you said - mine's
a 350 - little stiffer springs but still yields a nice ride. It was
interesting that the salesman wanted to find the build date because I've
heard "rumors" that there was a major flaw in the engine design that was
corrected after a certain date.


I believe the 6.0 came out in the 2003 model year, and for a while you could
purchase an '03 with either the 7.3 or the 6.0. The early 6.0's were indeed
fraught with problems, but as I understand it, most of those issues were
worked out by the 2004 model year, and by the 2005 model year, things were
essentially as good as the 7.3 ever was, at least in terms of reliability.
The approximate build date of your truck is printed on a sticker on the
trailing edge of the driver's door, in the format mm/yy. The exact build
date of your engine can be read on the sticker on the Fuel Injection Control
Module in the format dd/mm/yy. The label on the FICM is difficult to read,
but doable. You'll find the FICM on the driver's side of the engine near
the firewall under the coolant recovery tank. My engine has a build date of
October 22, 2004 and a the sticker on the door reads 10/04.

Here's what the FICM looks like:

I'd be interested to hear what the current diagnosis is, as well as the
dealer's remedy.
