An update... This past Friday, I took the car to Speed1 to have Dave B. take a look and give me a professional assessment of what is going on. Bottom line is the turbo is starting to fail, and it will get progressively worse. Ted nailed it with the failing turbine seal diagnosis.

While I'm happy that the engine itself is healthy, and won't need to be cracked open for a long time, I'm pissed that this turbo is failing prematurely. Like I said before, it's a BNR stage 1 rebuild, that I installed & fired up for the first time on 3/11/2011, and logged only 11,889 miles on it since then as of last Friday. And since I'm running stock boost control, it was never pushed beyond the stock 8~8.5 PSI boost pressure limits. Hell, the stock turbo had 136,XXX miles on it when I shipped it off to BNR for the rebuild, and it didn't smoke anywhere near as bad as this one does now.
