Yes you can change just the o-rings. the only issue is that when you push the piston out of the liner the rings usually break, so be ready to do more work to it. I use vegetable oil on the o-rings when I set the liners back in.

just a thought do you have an injector or 2 maybe stuck when tou ran the overhead what sequnce and torque on injectors talking about compression release these are not touch and back off injectors and in my experience plain engine oil works just as good as veg oil also when pan of check end play on crank and deffinently pressure test with pan off. (i also remember cummins revising the overhead set process so make shure u used the correct one)

Well, I've had some time to think about this. No time to do anything, just think I'm gonna try and shop around for a used big cam as they seem to be pretty reasonable and I could pick up a few much needed HP. It's gonna be faster and darn near cheaper to stab an engine than it would be to tear into this one again. The mil-spec stuff is pretty well limited to the oil pan and coolant purge tank, so any old class 8 engine should pop right in. Thanks for all the advise.
