Adapter Oil Catch Can Mazda Skyactive 2.2 Diesel

Description
Here is my problem solver for Mazda Skyactiv 2.2L diesel engines (especially from MY 2016 onwards)
As every Mazda diesel driver knows, due to the EGR control, these engines are prone to the sooting and clogging of the intake ports:
However, the EGR valve alone is not solely to blame for this situation, but also the fact that a significant amount of water and oil is sucked in through the intake via the crankcase ventilation at the valve cover (the mixture can be seen in the charge air cooler in the image below):
Engines from 2016 onwards are particularly affected, as these do not have active crankcase ventilation cleaning.
Therefore, here is my solution using a Radium universal oil catch can kit:
It actively supports the cleaning of the crankcase air that is re-ingested into the intake tract, and removes water and oil vapor, which therefore no longer ends up in the intake and forms a sooty mass with the EGR air, clogging the intake ports and potentially leading to engine damage!
The adapter replaces the original valve cover fitting with one featuring a bypass for connection to the oil catch can (original part):
Like the original, the flange requires 2 threaded inserts which
must be melted into the plastic.
Furthermore, my upgrade kit also includes
an adapter for the catch can mount, which is attached to the mounting bracket for the
diesel filter:
Again, you will need 2 of these threaded inserts for this.
Finally, I have also installed the Radium Catch Can Petcock Drain Kit and mounted it to the oil pan cover using an adapter. For this, I used 2 M3 + 1 M2.5 threaded inserts and a few M3 and M2.5 cylindrical screws.
This add-on is not essential, but it is very useful due to the poor accessibility of the tank.
Here is the result after 5000 km in the catch tank (top: oil / bottom: water):
IMPORTANT INFORMATION:
I printed all parts from PA6-CF and used HIPS as an interface material!
Due to the high temperatures and oils around the engine, ONLY this material is recommended!!!
