At the beginning of the discussion I was giving the OP a little benefit of the doubt. As more and more little bits of info and comments surfaced I came to the conclusion this was simply a neglected car that met its end at the hands of the owners. That usually leads to in what direction do the fingers point....
I take this to mean both engine and turbo died because the engine ran out of oil due to the PCV and like Admiral Farragut, "Damn the torpedoes...."
The BS about the PCV causing a production stoppage, the wife doing long distance commutes on the highway each day, the sludge and PCV issues, dipstick blown out, and all of the engine oil dumped just reinforces my conclusion.
The only missing info is did this engine quit at what point on the road, was the car towed in, and so on. Offhand, I'm theorizing (guessing...) that this problem happened with the other half on the road somewhere and I'm sure the standard "Oil light never came on" retort is hidden somewhere.
Either way, the OP has their name posted. If they feel so strongly, then sue Bob Moore. I've noted the name and will follow the court records to see if a suit pops up.
The online court records will reveal why they're suing, what they're asking for, and the final disposition and judgement in any case. With name duly noted, I'll post back in the future about "what happens".
