I have this engine(swapped) in my car(w124). I have seen it in a w210 so I was wondering if anyone else has it. Can you please tell me how many valves,cylinders etc it has? Also, is it a good engine or not?

I believe that is the naturally aspirated OM606 model engine. It is a 3.0 liter, in-line six cylinder.

I would suggest posting this on www.mercedesshop.com in the diesel forum. There are a bunch of forum members with this engine there, and they are a good resource for technical questions/answers.
