Disappearing oil

[o. l. t.]

Right now I have to do the oil separator. The truck was sold to family and I do what they are willing to buy. They have the separator, the back plate, and hoses so it will be a complete replacement of all the related stuff to the separator. The BMW guy here believes the backplate is to blame instead of the separator itself and says in our climate that is usually what goes. I REALLY wish someone had some pics of this done on a 4.4i, but I have been unable to find them for anything but a 3.0

This happened to me as well.
Had it changed oil. Definite 8 liters of oil was refilled.
Still no oil via the dipstick.
