I've recently acquired a 2000 clk55 and I've noticed that it smells of burning oil in the cabin when I have the fan on, and a week or two ago it developed a slight misfire at idle.
I can't see any visible smoke behind me during day-to-day driving, but I did leave a great puff of smoke behind me when I hit the kickdown a couple of days ago.
There are no leaks from the rocker covers or anywhere visible, no traces of oil on the manifolds either. This leads me to believe that it's burning oil.
The car's done 110k so it's well within its service life. There's a stack of service history to go with it and it appears to be well looked after. It seems unlikely that the rings need replacing but the symptoms point to that.
What are peoples thoughts? Has anyone experienced similar?
