[W126 Coupe] Timing chain and lubrication maintenance note...

[Camran Nassiri]

I replaced my timimng chain and all the rest that goes with it (e.g. tensioners) at 60,000 miles as per Jonathan's recommendation.  The mechanic told me that it was loose and could have gone at anytime.  As Jonathan put it, it's not always miles it has sometime to do with age.  My cost about $1,500
