I used to have an E23 (1983 735i), the PCV system in that car is simply a tube from the valve cover straight to the intake.
See item #11 below...Talking about simplicity!!!
With the E23 setup, oil vapor is burned in the combustion chamber. However, it is not much, the E23 consumed 1 qt every 5000 miles.
In the attempt to make things better, the BMW engineers manage to make my E53 M54 engine burn about 1 qt every 1000 miles!!! In other words, they go backward from an engineering aspect!
