On most 240D (W123) engines, there is an oil-air separator which has a nipple at the end which plugs into a drain tube. On that nipple, there is an "O" ring.

Does anyone know the part # for this O-ring? I looked on the forums and the 'tried-and-true' fiche from S.Atlanta MB and no dice.

I will post some pics tonight for clarity's sake.

Thanks in advance.
