Before reassembly I cleaned what I could from the turbo with brake cleaner, was able to get enough of it off so that if it continues to leak I will know. no idea how one would detail the turbo other than removing it and disassembling it.
This is how I routed the lines, 335D intake is slightly different so my lines had to go around it.
Bought a 3/4 elbow from oriley for about 2 bucks
The catch can ended up directly under the intake pipe and the catch can filter did not fit. So I just removed it and put the plug so it's a sealed system.
Final product
before I finished the project I drove for about 1/2 mile with the CCV sealed shut. the car was blowing so much white smoke that it totally blocked out the 2 lanes. I guess there is a lot of crankcase pressure and since there was no way for it to escape it just burned lots of engine oil instead.
