Best Cheap Test for BMW N55 PCV Valve/System - X3 X5 35i 535i 335i
Sharing the method I used to test the PCV system on a 2016 BMW X5 PCV system. There are a lot of videos and tests out there, I didn't find any that showed me exactly what I wanted to know so I made this video with some more detail. Hopefully this helps someone diagnose their system.
