Roll in a new chain and replace the upper right tensioner rail NOW

Check stretch every 30,000 miles and replace at 4 degrees.....

This is sound advice!
Replace all the upper rails, not just the one, they are inexpensive and
become brittle with heat cycling. Use a genuine MB tensioner only!
Chain is not hard to do, either. Inspect the cam sprockets for wear
while you are in there.
