Very interesting thread. I have some follow up questions if you don't mind. More of a general nature than specific. I see the M102 has a single row chain. Didn't realize this. I've not heard of that being a problem on these compared to say, the single row chains on e the early 380 V8's or the 200, 230 four cylinder engines. What's different with these ones?

Also, how does a Mercedes head get to be unusable after less than 100K miles? That seems aberrant on a car of this era.

Lastly. How do you post these pic's to the forum? I need to find an alternative to photobucket.
