I have been a mechanic for the local school district for 21 years and have a good working knowledge of the 9.0 liter diesel engine.these engine are known as "parent bore" engines, no sleeves. THey were very relieable engines except for some head gasket failures, IH revised the head gaskets several times which corrected the problems,the driver would shut down the engine and when they went to restart she'd dump water right in a cylinder creating a hydraulic lock,never had to plain any heads, it would just leak around the water passages,sometimes they'd blow water out of the radiator,but the changes in the revised gaskets corrected the problem. These engines are direct injection engines and use a bosch in line injection pump and bosch nozzles,they would start in temperatures down to 10 deg.without being plugged in and would give around 10 MPG on a long trip(on flat ground as it is here in N.J.),all had 5 speed spicers behind them, most of these engines left with over 200000 miles on them,must of them had the original inj. pump but had to change the inj. nozzles to pass state emissions,they do smoke black on snap tests but will pass emissions test with a little work.HP was around 190 hp.The last ones we had were sold at auction here in NJ,driven to california, and from there driven to mexico.
