1930 7-45 Mystery Leak?

What might be the source of this stain just under the valve covers? It was worse before I wiped it off - some crungey yellow-green stuff. It wasn't there before I took my Packard out for about an hour-long drive, the first in a while.

I took the 1930 out for the first time since I had the radiator rebuilt during the pandemic. The radiator rebuild and several surgeries (on me) have kept me from driving the Packard for the last several years, but I've been starting it and running it in place at least once a month.

It started like a champ and ran like it just came out of the factory! When I got back after the run I noticed that spot of gunky stuff. My first thought was coolant and...oil? Am I going to need new valve cover gaskets?

1930 7-45 Dual Cowl Sport Phaeton. Engine rebuilt in 1958-59 by my dad, maybe 20K miles on it since. Unfortunately my dad passed before I got to ask him so many questions about the car, but thanks to the Packard clubs and forums like this I'm keeping it alive and healthy.
