El Guapo - Oil Leak Found?

As it happens, I still had an oil leak on El Guapo, after changing a gasket on the top end of the engine.  For some reason, it was very obvious where the leak was coming from this time, as I could see the oil pumping out with each kick of the kickstarter.  Any guesses based on this photo?

Not quite made for this engine..  I have since sealed the part with gasgacinch
