I bought a Jabiru one, dont think it achieved anything much.
An issue with Jabiru is that they tend to pump out good oil to a set level, this could be an issue on really long trips. Have to work out real oil burn which is tricky.
A lot of people overfill and get the perception the engine is burning the oil up.
CAE vent the blow off pipe to a different part to the rear of the engine.
An issue is maybe the small diameter of the oil fill tube and this fixes it. Now they have a catch can too. Mine uses almost no oil without this.
I also have on the bench a different style, and new,catch can here I could sell cheaply. Wasnt cheap to buy. Made specially for 3300.
Pipe with baffles inside that sits alongside coolong duct, Not required as i now have CAE engine.
