On my 1983 240D My vacuum door locks don't work at all, my car's engine shut off is a little slow(1 to 2.5 seconds delay), and my car uses more oil than diesel (almost--a quart every 200 miles.)
Of course, the rings may be passing oil (I rebuilt the engine without reboring), but I would like to thoroughly diagnose the problem before I re ring the engine. The engine has lots of power, so I dont think it can be using that much oil.
