My car, a bmw x3 2.0 petrol, uses 1 liter of oil on 30 km. It doesn't smoke blue when I start it when the engine is cold, nor when braking hard when downshifting, so I don't think the valve seals are the culprit. I see that there is more and more blue-grey smoke as the engine warms up, and there is a lot of blue smoke when accelerating after idling. I have had the car at the workshop for an engine check and they found no faults with the crankcase ventilation and the compression was good and equal on all cylinders. This engine has been run too hot once by the previous owner, so I suspect that the oil rings may be worn/damaged so they are the cause of the high oil consumption. The oil rings may be bad even if the compression is good?

Could be the oil rings or it could be the head gasket.
