Zeus,

I'm assuming you read ILUVMILS' comments in the this thread.

'98 E320 burning lots of oil

Particularly:
"In my experience, problems with M112 valve stem seals are virtually non-existent. The only time I've ever replaced them was as a pre-caution, when the motor was torn down for other repairs. All the oil burners I get at my shop end up needing new piston rings, at best. I've seen plenty that needed engine blocks/pistons too."
