I appreciate the reply but I sorta wanted to get an actual head count of those, such as I, that have experienced a breakage personally. It seems a great deal of opinions keep popping up on this subject and I would like to get a consolidation of actual experiences.

Incidently, I doubt anyone changes their oil more often than we did on the 420S. It, still, jumped timing and broke with just over 100K on the odometer.
