So I made a little plate to keep the plug in.
Uuuuunfortunately...

Erwin83:
Not so much a puddle.. just a good 5 yards of spray, oil on the ceiling, bike's left side covered...

At least no questions about the performance of the oil pump...

Erwin83:
With regards to the solution of the actual leak.. I found that the plug was snug in the bore when the outside of the plug is around 1 mm deeper than the surface of the cover. That would mean that the oil pressure always pushes the plug out that 1mm, creating a gap between the bore and the aluminium of the plug. As such completely relying on the O-ring for sealing.

I have now placed a small bit of gasket material between the plug and the actual gasket, therefore keeping the oil plug in a bit deeper mechanically.
I also did some better cleaning of the bore and plug.
Let’s see if that does the trick.

;D ;D

Bryanj:
This suggests to me that the "pip" on the plug has been shortened somehow
