1999 C230K (202.024) 102k miles - I would like to replace the PCV valve. Not sure where it is located. Is it the plastic component screwed to the side of the valve cover with several hoses connected to it? If this is it, I noticed some oil residue on this piece. Does anyone have the MB p/n for it? I searched Google but found nothing about the replacement part. Are there any special precautions I should take while replacing it?

Thank you for your assistance,

Buck
