So seems like they haven't drained the old oil long enough and topped it up with new oil, and overfilled it, and now excess is coming out via blowby and into the catch can...
Or my engine is doomed. But so far the timing of the oil change and the kms done, vs the amount drained, adds up to too much oil. I hope so anyway...
Thought I'd update this for future reference in case anybody else questions excess oil out of the catch can.
