I joined the group from Colorado with my 2011 E350 4Matic with 160,000 miles.
There is a white smoke coming from passenger side rear the engine. It starts smoking when car slow down or fully stop. Engine temperature looks okay. Coolant level is okay. No noises coming from the engine. It spilled oil in a hand size area on my driveway. I have not lift a vehicle before to go under of it.
After a lot of research in the forum, I removed the engine cover this morning to take some pictures. Upper piece of engine cover had some oil under (same side smoke is coming). What I see under the cover match with the conclusion I gathered during my research. Engine Crankcase Vent Valve is covered with excessive amount of oil. The pipe connects to it also covered with oil. Valve cover gasket also sounds like the issue. Any thoughts? Here are the pictures (driver side is completely dry):
Engine Crankcase Vent Valve Next to engine oil cap The pipe connected to Engine Crankcase Vent Valve also has a lot of oil.
