There are 2 sides to the PCV system; the clean side and the dirty side. The clean side only accounts for about 5% of the total blow by. Why GM chose to address only that 5% is beyond me. As the name suggests most of the problem lies on the dirty side where about 95% of blow by passes through. Many choose to only address the dirty side with a catch can but running something on both the clean and dirty side is the optimal solution.
