Hi, im new to this forum and have some questions regarding crankcase pressures in my BPW engine. Please dont talk about replacing the turbo and injectors, no issues there. I over time i have positive pressure building up in my engines CCV system. I removed the oil filler-cap with engine off and that relieved some amount of pressure. I tested the CCV vent by pressurizing the crankcase through the line going to N75 valve and that verified my concern. This causes blowby issues to my turbo, wich again generates smoke at idle sometimes. Question is: shouldnt the CCV system prevent this from happening in the first place? Or should i even bother taking off the cover and look at it? . Thank you very much in advance!
