Car is back home, running absolutely perfectly. Shop foreman tore the engine down completely, replaced every part that was affected OR could have possibly been affected, including main bearings, timing chains, chain guides and ramps, etc etc etc. Here is my 30K dual row bearing:
A few other pics:
Although it took a long time (~50 days), I couldn't be happier with how the dealer handled this situation and the thoroughness with which they approached dealing with the issues. The Shop Foreman was tremendous: when I went to pick up the car we met for about a half hour, along with the CS Manager, and he walked me through exactly what had happened, and everything they did as a result. It was clear he felt horrible about what happened: I managed people for decades, and my BS meter never went off; his angst was sincere.
Next step? Drive and enjoy it, and bring it back in about 600 miles for a thorough check and oil change. Oh - the IMS bearing looked fine (for what that's worth), and turns smoothly. It goes back to LN/IMS Solution tomorrow.
