W123 M110 : what does this part belong to ?
Just discovered a "dowel" protruding from the front right of the engine head.
There seems to be a "twin" just below it, firmly in place.
The dowel was halfway out, but I didn't dare pull it out all the way. Next trip, the same, just pushed it gently back into place, but what is it ?
Could it be placeholder for one of the chain guides
Neither the MB service CD, Haynes nor alt.auto.mercedes has given me any clues.
Will it be expensive and difficult to repair (probably) ?
