Russ, I sure wish that we were closer together. Your price almost makes me want to go out and blow mine intentionally.
I just paid a shop ( Buick dealership ) about $250, and that included me bringing my own oil and filter. And don't say that it was because it was a dealership, because all of the shops around here that have a good reputation for being good at turbo repair charge about the same. I have found out that most of the dealerships will honor their warranty work somewhat better than independent service repair shops.
