First of all, it's not December 31, 1969, but instead is April 9, 2008.
I have a 1990 300TE that had a heater hose break, and the dumb fool poured cold water into the radiator bottle. Now I have oil in the water (though no water in the oil!). Advance Auto sells this bottle of green fluid that GUARANTEES to fix leaks in head gaskets, cracked blocks, valve cover gaskets, etc. that is added to water. The big hitch is that the car must be able to idle for 50 minutes while the stuff does it's thing. One thing I found out; a cracked block is not conducive to idling more than a couple of minutes - much less 50 minutes (no wonder it's guaranteed to work if you follow the directions to the letter).
I'm convinced the oil has the radiator tubing all clogged up & oil lined. Obviously this reduces the heat exchange needed to cool the coolant. What can I get to "get the oil out" of the radiator & coolant system, (no - prestone flush doesn't work), and has anyone used this crack sealer product? It's around $60 for a 32oz bottle.
I love my Benz, but can't afford to get a rebuilt engine.
