1988 Other Mercedes Benz Models Engine Overherheating

1988 Other Mercedes Benz Models 6 cyl Two Wheel Drive 97767 miles

I got a partial valve job and a head gasket replacement. After a week or two I decided that I was chilly and needed to use the heat. The car began to overheat, up to 120, but as long I I didn't sit and idle I could make the Temp reduce.

Well the other day, the Temp went above 120, and since then, it won't reduce no matter if I drive or what. It now shuts off. It is no longer my happy little car. It makes a smell and shudders off. However, the oil is not milky, nor is there water in it. Nor is there smoke or any other typical signs of a blown gasket. BUT, the radiator is cold and the engine is hot.

What in tarnation is going on? I would give $$ but I have given it all to this mechanic, who has run out of Ideas. I think that there is sludge in the line and no fluid is going to the radiator from the water pump IF that is even working.
