I'm going to find another independent mechanic in the area (the car is a few hundred miles from home).
Here's how I'd paraphrase the dealer mechanic's current theory.
Catalytic converter is plugged up with carbon, causing the engine to fail and ultimately starving off oil to the turbo.
Basically they are pinning everything on lack of maintenance by the original owner.
That owner had the turbo replaced under warranty and then sold it. We blew one turbo (admittedly after about 5k miles on synthetic oil) but since the replacement (which also included Subaru 60k mile maintenance) we have changed the oil every 3000 miles.
We didn't have time to change oil before our trip, but we are right at 3000 miles but they are giving us the "oil is black, dirty and filled with metal shavings."
Can a catalytic converter really take out all those other components, and if so, under what circumstances?
