I read another post on a 97 or 98 E300 about having to change the timing chain at 125K miles, I forget who the post was by. My question........was that an unusual occurance or should I worry about my 96 E300 with 290K miles? If I ned to replace the chain can I roll a new chain on like I could on my old 83 300D? Just thought of another question there is a shop in town that can check injection timing with a timing light would that suffice to find out the amount of stretch the chain has or should I just remove the valve cover and roll it around manually? Thanks for all of your help.
