Now pull the head. Sometimes if one cylinder has no compression, vs just a very low number, but the motor still runs it can just be a bad head gasket. And if that's the case that would be good news all things considered. Resurface the head, clean the mating surfaces, and put a new gasket on and he just may be in business. I wouldn't get his hopes up though...but don't give up all hope either.
