If the exhaust turbine shaft seal is damaged then this will allow oil to leak into the turbocharger turbine housing which can produce smoke particulary at low speed. The damaged turbine shaft seal can also allow exhaust gases to leak into the turbo centre housing and into the crankcase and come out the breather. If the turbocharger is also rubbing or binding then low boost will result and electronics will only allow engine to go to fuel ratio fuel position and not rated fuel position which will limit power.
