I have a 1990 240DL, I was getting oil into the intake manifold from the
crankcase ventilation system. I took the car off the road for one year, then
the crankcase ventilation damper was replaced. This remedied the oil in the
intake problem, however I now have a new problem. The engine runs rough at
idle and is running very rich. (black smoke out of the exhaust) It runs very
roughly when it is first started cold. Once it warms up it runs much better,
but still has black smoke from the tailpipe. Could this be caused by a
faulty sensor somewhere in the system and which one would it be if that is a
possibility. Before I took the car off the road, it ran well,and without the
black smoke, but had the problem with the oil being forced into the intake
manifold.
