So I went out today to do a new Datalog after finding that the nuts that came with the S280 turbo had backed off and the subsequent manifold to turbo leak may have caused a false knock. I replaced the nuts and studs with OEM and torqued everything down and went to do a Datalog. When I backed off the throttle after hitting the 7k limiter I got a huge cloud of burnt oil smoke out the tail pipe. By the time I got home the car would not idle and blue/grey smoke is pouring out the exhaust as I drive. I emptied my new catch can and I got about 2 oz of oil out of it. Any ideas as to what damage I may have done? No codes showed up on the AP???? It's burning a lot of oil!
