Part 1 of a 3 part series on my failed timing chain tensioner which was installed by a non MB Repair Facility in a not so professional manner - please make sure to watch part 2 which will follow in a couple hours for a fairly detailed failure analysis and the corrections necessary to get everything back to work correctly
