I replaced the o-rings in the oil cooler of my 96 7.3 earlier this year.
It was a bit frustrating but really not that bad. I found it was easier to loosen my left motor mount and raise the motor a bit to get the cooler out. I think it's easier on the 99 and ups.
There's also a little valve in there that will fall out on the older models. Without that, the oil drains down to the pan and empties the reservoir that runs the injectors. The truck won't run long without it.
On later models, I think there is a retaining ring so the thing won't fall out.
I'm getting up to the 350K range. Aside from a bit of leaky diesel, likely from the abyss know as the valley of many lines, it's good.
Regarding the 6.0, my friend's company actually started selling off their 6.0s and hanging on to their older 7.3s.
