Bmw 116d in last week. The car was not drivable as as soon as it got warm looking in the rear view mirror was a smoke screen !
The breather valve in the rocket cover was blocked solid which the caused the excessive crank case pressure which then forced oil into the turbo causing heavy white smoke.
This customer had paid every year at a dealership in Exeter for a service ! There is no way the oil could turn to sludge like this unless it’s not getting replaced when it’s supposed too ! Worst one I’ve ever seen !
Engine flushed 3 times with 3 oil filters as well. New cam cover and good drive , no smoke at all now and power restored 🙌
