The 112/113 Engines have a spec for a stretched chain...No replacement data.
(IF) the 112/113 engines are like the 103/104s They will last a long long time..as I Have never replace a chain in a 103/104
The old style engines ..V8s had a single row chain..that was updated to a Double row chain...
Its not the chain that goes bad...either the chain tensioner or a broken chain rail
When they go it jumps time and bends valves
Why is there the Need to Eliminate Responsibility for ones Actions by Blaming Everyone Else
I have a '98 E320 (112,000 miles) and a '99 E320 Wagon (150,000 miles). Both get synthetic oil, changed at 3000-5000 miles (since I've owned them anyway). I know the timing chains are known for long wear, but I'd really like to check stretch on them from time to time, but I don't know what the process is to do this check. I know this has probably been covered 100s of times so I apologize for the repetition, but I haven't had any luck finding the actual "how to" instructions in any searches.
