Check valve guide seals. They will let oil leak past valves get into combustion chamber and then you have gunk. Also bad turbo seals, and in older Mercedes bad diaphragm for vacuum pump will let oil into intake which then becomes crud.

I'm told it doesn't take long, because it's kind of a self-perpetuating process unless the majority of your driving is Italianate in nature. Probably being indirect in nature (a 6XX part number) it's a lot more sensitive to glop in the prechamber. Start with glop, and it stays that way for awhile. And once you're over the threshold, it never goes away. -- Jim _______________________________________ http://www.striplin.net For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://striplin.net/mailman/listinfo/mercedes_striplin.net -- No virus found in this incoming message.
