I just sold my 2002 7.3 and purchased the truck in signature. Mine had over 300,000 miles on it and still looked and ran like it did when new. I did have to replace quite a few items while I owned it. New trans at about 250,000, rear end at about 175,000, all Moog front suspension and steering components. Never had a single problem with the engine but I changed the oil every 6-7000 miles and had it checked over every other year by a good diesel mechanic.
I ran a tuner with the towing program, and had full gauges on the pillar along with a
ScanGauge on the dash front. My next mod, if I had kept the truck, would have been to put in a larger exhaust. With the tuner, I had to be careful with the exhaust temps and the larger exhaust would have helped with that.
I also had a DeCelerator exhaust brake but cannot recommend that to anyone. See my post
here for information on that wrong turn!
The truck pulled our trailer very well but I had the hots for a new truck so the old reliable 7.3 had to go. Did not have any trouble at all getting rid of it. That is probably the best, most reliable engine Ford built. I absolutely love my new Ram with the Cummins however.
