582 rotary valve oil?

[GyroPaul]

Have 6 hours on a new 582 and yesterday I noticed that some of oil had been forced out of the RV oil reservoir. Never had this happen on my other 582 with over 200+ hours on it. I didn't think anything would push pressure back to this little tank. I thought it was just a gravity feed.

Some possibilities-
Some remaining air in the cross-shaft cavity expanding under temperature rise. Make sure the cavity is fully bled of any remaining air.
A bad internal crankshaft seal. Perhaps will bed in with time seeing this is a new engine?
A bad water pump shaft seal. This will show up as water or a foamy emulsion in the oil.
