I'm curious to know more about the days/months/moments leading up to the failure. I want to do everything I can to mitigate further damage. What's really scary is that it seems like the timing chain guide can fail with little warning.

Yep, there was almost no warning other than the whining sound the day before, which sounded like a failing power steering pump.
Strictly BMW said last year they've done like 3 or 4 of these jobs on the 4.4 engine. With the guides it seems to be an issue of age rather than mileage. I suspect this will be a more prevalent issue in the coming years.
