Default High side flapper delete - 04-26-2020, 08:20 AM

Hey, guys. Recently I deleted the high side PCV with a factory flapper and installed a catch can to open the atmosphere. However, immediately after that, blue smoke occurred. Blue smoke has disappeared when the original BMS catch-can recirculation method is restored. Shouldn't the high side delete the flapper? The low speed side is building the same system as the RB external system. (Without head port plug)
