Yes, I do see the smoke and do not keep the oil level above the midway mark between Add and Max. I usually let it drop to the Add mark or slightly below before I add 1 or 2 quarts. I'll check it the next day and usually it's nearly exactly at the middle of the add/max. Luther, Another possibility, easily checked, would be a cracked diaphragm on the vacuum pump. the vacuum pump would then be pulling oil from the chain area and blowing it, unseen, into the intake. Just take the line that goes from the vacuum pump to the intake manifold and put it in a can or bottle for a couple days. There should be zero oil in there. Contrary to some opinions, the turbo engines do present a vacuum to the valve guides quite often. Whenever you are idling or coasting down there will be negative pressure there however slight. If a seal has popped off the guide it will definitely leak oil. Air pressure is not needed to change the seals on our diesels. With the appropriate piston at top dead center, the valves can only drop about 1mm or so. The threaded valve stems make it easy to remove the spring for servicing the seals I have replaced valve springs and seals on a 240D in a couple hours. Just some random thoughts.
