After I read your description, I understand that you no longer have
any oil separation. You are basically feeding all the oil and gasses, from the valve cover, directly into the turbo inlet. Sounds like a high turbo wear set-up to me. Especially, when liquid hits the turbo blades at speed. Also, with this scenario, you may run a very high risk of runaway if their is a condition of vacuum in the turbo inlet.
You can check with the pros here. IMHO, sounds
very risky to me.
Crankcase ventilation is not an emission feature. It is to keep gases from building up in the crankcase.
