STRESSED OIL LOSS????

[jsevo4]

My car is losing oil (burning) it is white too grey, but has done from the word go first of all

it was the turbo as was doing on let off and reacceleration this was solved with new turbo.

But the car is still burning oil about 1mml per mile not a great deal but def noticable.

Now i know this could be down to crankcase press (oil rings) or it could be guides,seats etc.

Would this be major concern or will it be fine for a while as looking at rebuild and dont want to f$$k

the engine too early.PLEASE HELP AND ASK ???
