Seems quite unsettling to have your car go boom to all us DIYer and non-wrenchers.

No warning whatsoever, no metal or other debris in the oil, all chains intact, IMS intact. No compression in all cylinders.
It failed while trying to start it. Cranked over about 2 times, fired a plug or 2 then spun free, no noises.
This is the first engine failure I've had in a lifetime of enjoying numerous Porsches. I performed all maintenance better and sooner than Porsche recommends. Very unsettling.
Some day I'll have the time to tear the motor down and see what happened. My best guess is that either the sprocket on the IMS or crankshaft slipped on its shaft. I'm in the process of getting a used motor ready to install.
