smoke
I have an E300 (1996- Diesel) and had the hose left off after service and experienced very similar issues (esp the smoke). Did your CEL come on yet?
keep us posted.
i think my problem is deeper ...im also loseing a little water as well .The radiator overflow pipe is dribbling water from it ....i think the head gasket is gone .dosent appear to be a bad job ..would you folks use new head bolts when replaceing a cylinder head gasket ....any suggestiond welcome ....thanks
Head gasket would have oil mixing with coolant so your expansion tank would look like a mocha frappachino choclate shake or your oil would look fouled in a similar manner, pull the dip stick and take a look. Are you overheating at all? Thats another sign.
Just some thoughts, not an expert but my 190E had a head gasket failure and those were symptoms of mine.
