Stymied. 1990 Mercedes 300E. Oil in coolant even after several flushes. No water in the oil. Oil consumption 1 qt per 1000 miles. Runs great. 26mpg. No steam or oil smoke out the tailpipe. Theories so far: head gasket (but why no water in the oil?) Or timing chain cover gasket. Ideas?
Many thanks. Funny how my neighborhood garage, run by hard-working Vietnamese immigrants, diagnosed it better than the M-B dealership. But then, the dealership wanted to replace a whole headlight assembly at $500 when a $4.99 plug would do the fix. Thanks again.
