Coming down a hill my exhaust brake kicked in and rpm went to 4k for about a minute. Shortly after coolant got hot. Pulled over, hose that I think feeds the oil cooler had blown off. It's located too side passenger. Between the oil fill reservoir and the fire wall. Between the turbos and the wires to the computer. I'm stuck a a gas station that only has havoline universal. Can I just fill with that and make it home about 400 miles away?
Not sure what you're referring to either, but if an oil line disconnected you will most likely need a tow if you can't repair it. It doesn't matter which oil you put in if it's being pumped right back out.
Only had access to distilled water. Just made it home last night. I assume first thing on the list is a complete coolant flush. Then oil change since I did see it reach 230 degrees. Anything else I should be looking at?
Then move on to why the coolant hose blew off the oil cooler? Any thoughts?
Is 4k rpm normal for exhaust brake? Seems to me like that is extremely high. I've never seen it go up so high.
Yup, that's at the upper limit though. The book says to not exceed 4,000 RPMs.

Yep, that will happen when the coolant circuit overheats. CJ-4 oil has to meet numerous benchmarks, among them is viscosity at 302° F and volatility at 482° F. 230° is well within design limits for this oil.
The point of no return for engine oil temp is 425°. This is the temperature at which your plastic standpipe in your oil filter housing will melt down and flow into your oil passages. At this point the entire engine is junk, as there's no approved way to clean the melted plastic out of the oil passages and bearings.
