Looks like you have nothing pulling from the crank case, so your PCV is not doing anything. Try this equally crappy drawing for what should work to fix it. Eliminate the hose with an X through it. Add the yellow and orange hoses. The orange hose should connect between the filter and turbo for vacuum. You will need a one-way check valve in the yellow hose to make sure the airflow is only toward the throttle body
Darth is correct...you need vacuum in the equation for the crankcase to be properly "evacuated"...
Its not that difficult. The two breather lines coming off the valve covers need to T into 1 line. That line needs to go to the inlet on the catch can. The outlet needs to go directly the fitting behind the throttle body. That is the only way you can get vacuum to assist pulling blow by gasses out of the engine. Also you need a PCV valve on the outlet side between the intake and catch can. I am unfamiliar with turbo setups but it looks like the turbo breather line needs to connect to the valve cover where it is capped.

Yep- basically, your original drawing has no airflow through the crank. You need air going in and air coming out, and you need to make sure you don't pressurize the crank case. Your turbo breather needs to go to one valve cover and the inlet on the throttle needs to go to the catch can. PCV valve between other valve cover and catch can. You need a check valve between throttle and catch can to prevent pressurizing the crankcase.
It sounds more complicated than it is, but once you get it, you'll know it right away, as you'll stop smoking, and the car will run smooth
