Hi I have a 2016 stage 3 focus st. I'm running 5w30 syn oil and have a stage 1 damond occ. After extended idle of more than 30 sec I get blue smoke out of the exhaust. I can not figure out if I should gut my pcv and stick with my damond occ, buy a pic plate or get an rx performance occ. Any help is appreciated. I have searched and read many forums but with no solid answer that I understand.
