Timing Chain Question
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.
Thanks a lot....The help is much appreciated.
