looking on the picture of post 122 under the line that comes from number 3 there is this horizontal cylinder. The right end (back of the car) is closed with a round cap that you can simply unscrew.
Inside there is in the centre a small 6mm round passage that goes to the intake valves (it splits into 6 somewhere in the head). I closed this hole with a piece of silicone hose and a crew.
running this since several months, no issue, no oil leak of the cover seal and a lot of blow by because now all the "shit" is going out via the catch can (actually I vent it to the atmosphere at the back of the car via a 22mm pipe, it smells like a shit for the others behind me
)
