Man, this good to hear. I also read your previous about the mileage. I get even more stoked about owning this truck. It was great find for me and I feel truly blessed. I kept feeling a tiny bit doubtful just due to the nature of a V-8 diesel, but I keep getting reassurance that this particular motor was pretty much bulletproof.

Again, just more confirmation. I think I have a good one!

However, I'll note there is one typical issue that is known that can shut you down immediately without warning; the CMP (cam position sensor) can go out out. Most die-hard folks carry a spare in the glove compartment; about a 15 minute in-field exchange. When it dies, you're stranded until swithed out. Other than that, it will typically always run and get you home. You also might want to drain/flush/fill coolant and make 100% sure to use a coolant with SCA in it, or add some after the fact (depending upon your choice for coolant). The old 7.3L has issues with outer wall pitting from cavitation if the SCA is not added, and can get so bad as to pit all the way through the cylinder wall in extreme cases! I got this straight from a Navistar product engineer I spoke with back in 1999 while at Ford; the engine plant was right down the road from the Ford plant where I worked.
These are easily 500k+ engines if treated well. Partly because they are very robust in their general build, and also because (from late 1994-97) the power was good, but not overwhelming, and so they can sustain hundreds of thousands of miles. When folks "tune" them with really high-power situations, they can have issues.
I presume you have the E4OD tranny? Did you transfer the pan over?
'suuup Dave! All of the above mentioned have been taken care of. I read about the cavitation on the Ford Truck forum and that is first thing I did. I did a full flush with Fleet Charge SCA Coolant from Napa. I saw some photos of the cavitation when it is serious....yikes!! I need to do a coolant filter as well, but I'll do it when I get more time this weekend or next. i need to get the parts too. I do have the E4OD. Unfortunately the pan was given to another person with the same tranny long ago. I wasn't sure I would ever have another Ford, so I passed on the generosity that was shown to me.
I also changed out the CPS a few days ago. It stalled on me going in reverse a few tmes, which is one of the tell tale signs, so I got one from an International dealer down the road from me. It solved the problem and runs a bit better. I put the old one in my toolbox along with another IPS just in case.
AFAIK, no tunes ever on this truck. It has had new injectors at 160k, a 3" downpipe, and 4" straight exhaust. I put a Riff Raff 6637 Intake kit on it, which is essentially a Donaldson filter and an aluminum pipe to attach to the intake tube with hose clamps. NO K&N!!
As you probably read, I just plan on running Delo for 7.5-10k intervals with an MC filter. Good to be back here. Hope all is well with you! How's the DMax doing?
