My statements are 100% factual.
The catch tank does remove the aerated oil vapors from the PCV system.
You continue to overlook/ignore the other contributing factors that lead to carbon buildup on the intake valves. Seepage from the valve guides being the secondary cause. No one ever claimed a catch tank system would eliminate seepage from the valve guides.
I wish you luck and look forward to your campaign for a valve guide recall from VW.![]()
