Video: Are oil catch cans the best solution for PCV system issues?

Direct-injected Volkswagen GTIs–just like our own 2017 Mk7 project car–are known to have issues with the stock PCV system.

My mk6 fills up about 8-10 onces of fluid (water, oil, crap) once a month or in about 1300 miles if on a trip. Runs like E36 M3 if it is full or frozen, and wow does it smoke.
