sounds like a hole in a piston. What does the smoke smell like? Fuel? Oil? Antifreeze?

Yeah. You definatly have a problem. He's got real bad blow by. Meaning the compression rings are not doing their job and the compression is leakin into the combustion chamber and out through the PCV valve and breather tube. Or worse he has a hole in the piston. The only thing that I am confused about is the radiator thing. That is not a good thing obviously but usually when that happens you blow a head gasket and not the whole engine. But if he was running it crazy hot for to long the oil could have broke down and the pistons scarred the cylinder walls and damaged the rings. I would start by getting a compression test done. Good luck.
