The rubber bond in the harmonic balancer can decay, which causes the balancer to move and work its way toward the timing cover. If the balancer comes into contact with the timing cover while the engine is running, it will fracture and damage the cover and potentially other surrounding parts. The harmonic balancer should be inspected at every service.
High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.

2005 Mercedes-Benz E320 4MATIC Reviews
My pre-owned E320 is beautiful but with only 76k mi I have had major repair in '11 and 2 more to come i.e valve cover gasket replacement and what sounds like a brake boot so I've been told. I've had it for 5yrs, a light driver and keep on top of my maintenance but these problems are huge and getting costly and they say it's not even broken in! Bah! I feel these issues are too early in the life of this vehicle. My recommendation, buy new.
