Sounds like a cold start. Mine is rich enough on a cold start that if I back through where the exhaust was I can smell fuel even with the windows up.
I've always heard that, but I disagree. I believe Gaylon is right... Coming from a guy who's turbo leaks oil past the seals on occasion and had to have it rebuilt twice already. haha.. I KNOW I was burning oil and it was a HUGE white/gray cloud behind me. Perhaps the grayish could be called blue by some, but it was more white than blue.
it's a journal bearing turbo.. Just straight oil, no water/coolant
