So what's the similar (ish) issue on dry sumps? I thought the oil pressure was always on in those, so it shouldn't happen, but I'm sure I know enough about it....
There is a non-return valve in the head of the left bank of dry sump engines which should hold oil in the heads. This has been known to fail causing a slight rattle. There are a few threads on it.
