timing chain and cam failure on 92 500sl
 

hi, on startup i heard snapping sound car was warm, it broke the outer left cam and the chain, has anyone heard of this problem at 90K miles ? Is this a Mecedes issue ? Boderline suicidal over it, Thanks, Sven.

Unfortunately, I have seen this. The older these engines get, the more I see in this condition. The rails become brittle after ageing. The only fix is to replace the rails and chain at 90k mile intervals and NEVER miss an oil change.

Mercedes V-8's are known for this in the 80's and now here come the 90's engines.
