[W126 Coupe] Timing Chain

[alal30319 at gmail.com]

I did the timing chain on 6 of my cars late last year and did exactly what
your mechanic suggested. What I replaced during the process were.

Chain
Chain Tensioner
Chain Tensioner guide rail
Upper rails
Oilers
Valve cover gaskets

All easy and part of the job.
