The Benz' you referred to do have two row chains, and tensioners too. Oil pressure fed ones. They age, and sag, and the chain jumps time, and yes, crash valves. The single row chains were not strong enough to pull the valve train in the V-8's.

The 944 16v engines use the same rubber belts to turn one cam. The other cams are connected to the first cam by chains inside the engine.

Like I said, I really liked the performance numbers and the look of the 3 litre S engine. Then I looked under the cam cover and saw how it all worked. I realized I wasn't going away from the rubber belt cam drive in an interference engine, I was compounding the problem, and walked away from the car.
