Water in our oil, or just alot of hot air?

Seen the same on VWs when they only get short ground runs.

The small oil quanity probably exagerates the problem, but it's there
in all reciprocating engines.

As to the hot air aspect, what's in the cylinder after shut down?

If you pull the mixture, the cylinders are cleared with a few blades
of clean (?) air before the prop stops.

Turning off the switch, however, leaves some fuel in the chamber.
One of them is probably under pressure too.
