My experience with that engine brought me to a conclusion about it that it Could work- IF the owner of one scheduled changing the EGR Valve about every 80,000 miles? Expensive! At the time, if I recall correctly, every time the engine did bad things, it was because of the EGR, and bad things normally happened every 90,000-100,000 miles. Also, if I recall correctly, the EGR was about $1600 plus time, labor, and the truck out of service. The time on the ramp, IH concluded the EGR plugged, which made the turbo overheat, which made the bearings let go, which let oil run thru the injectors, which made the whole engine zoom out of control and not turn off.
But that little 13 liter tank engine actually pulled tremendously for its size. I pulled full gross weight back hauls from Salt Lake City over the Rockies, back to Indy. It wasn’t a Speed buggy, but it did as well as when I was in a 2005 Columbia with a 15 liter Cat…….My Boss said that if he wasn’t working for a Corporation he would pull all the emission crap off and he believed it would be a decent engine afterwards. I’ve heard of many being sold to owners in Mexico. That’s probably what those guys did with them????
