Ah, I thought you were referring to the W116 300SD.
The diesels have a very high 21:1 compression ratio. They are very much an interference design. A broken timing chain will let the pistons hit the valves and (most of the time) break the camshaft and/or towers. It's very rare to get a broken timing chain in the diesels where a new chain is all that's needed.
