Yes agree BUT we have had more than a few leak from a corner of the head, down the block and totally soak the undertrays, so no they don’t mix oil and water when this happens.
Seeing this a fair bit and it was very common on the older 1.8 motor out of both the E36 and E46 3 series, did many of those at the time, in fact on those engines it was fairly regular but it does happen occasionally on these newer engines too.
And when this occurs there is zero coolant and oil cross contamination
Next one we do I will post photos with head off and show offending oil leak.
