Truly flushing the cooling system requires some disassembly and/or an awful lot of water. Keep in mind that as you put water into the system you should be collecting what comes out and disposing of it properly. There are drains on the bottom of the heads to help drain the engine. Disconnecting the radiator hoses up front is the only way to really empty the lines and radiator. Disconnecting the heater hoses and compressed air to get the stuff out of there. Avoid the temptation to drive with straight water. Cylinder wall and stud erosion start quickly without the coolant additives. Test the system to make sure it is holding pressure when done.

Thanks everyone who have weighed in on this issue. So far I have flushed the cooling system, replaced the oil cooler and a fresh oil change. I took it for a test last night late to stress it a bit to see if there would be new oil migration into the coolant. The good news is that there seems to be no oil in the coolant now! I will flush again today and add distilled water and coolant. I think I am only getting about 50% of the coolant out of the system when I drain it. Any advice on how to get the maximum amount purged from the system?

It is running rough on start up. I also changed the plugs which looked fowled, but as I bought this bus after the overheat issue, I have no baseline of how it idled and ran before the incident. I will be calling on your wealth of knowledge as I proceed, but want to express my gratitude to all of you who have helped out on this, and on all the other panicked situations over the years. It is good to be back on the list!

Best, Finn 87 Pooh and 89 Roo
