I'd be worried as well.
1. How long did they 'drive test' it without sufficient oil pressure to the turbo?
2. How much oil did they lose, and did they run the engine too low on oil?
3. How much life was taken from the injectors, which were probably starved for oil from the HPOP?
4. An open oil line will reduce oil pressure system wide.....how long were the rods and mains subjected to this?
Due to the nature of these being very expensive machines....and you would expect the dealer to do it right.....after all, that's why they charge a premium.....I would go beyond insisting on turbo replacement. I'd insist on either a rebuilt motor, a new crate engine.....or if they are so damn sure it's 100% fine, have them back it up with a 100,000 mile engine warranty specifically mentioning pistons, rings, bore, bearings, both oil pumps, injectors, coolers, etc.
I wouldn't waste any time, I'd get right on it. I had a Cat dealer changing a turbo for me one time, and he said he lost a bolt...couldn't locate it with an inspection mirror. They asked me what I wanted to do! I told them it's their call.....if the bolt did go inside, they'll be replacing the whole engine. Mechanic was sure it didn't fall in, they agreed to start it. They covered the hotel, and the next day I picked up my truck with the new engine. (With a warranty as well!)
