After starting cold engine in the morning and idling for a few minutes white oil smoke comes out of the exhaust incessantly and only stops when I drive away.
I had the turbine modified to thrust 360 a couple of thousand miles ago but since the modification I drove the car with a faulty waistgate (it did not open and my barometer at idle did not show any underpressure).
Can the faulty waistgate have damaged the turbine?
