Crankcase ventilation.

The manifold bolts make sense as well as it is pooled directly in front of the carb, I need to run her up and just watch for a while. Thanks.
i'd go proactive on it. yoink the bolts out, mop it all up, clean off the bolts and slam them back in with some sealer.

you'd be waiting and watching a llllooonnnngggg time to see it weep.

the valve cover gasket is at least, generally, more apparent right off the jump.
