Looking at the two oil return pipes for the K24:
034145735G for aircon:

034145735D non aircon version :
034145735d_034145735d_1.jpg
Then the aircon version is actually installed so you have something as shown in the red circle:

Then if you run with a catch tank that vents to free air I believe you will have less vacuum in the sump and this will worsen the situation?
I'm wrong here or could there by something to it?
