Modern Vespa

Got another doozie. Coolant seems to be coming out of what I believe is the intake? I'm quite confused. I know that it's coolant 100 % but why here?? See image.

It's the engine vent, so oil fumes should be coming out of it. Check the oil level to see if there is any emulsion (oil mixed with coolant).

Oil looks good. No slurry. How else could coolant be getting into that engine vent??

As was said, that is the crankcase vent. I'm not that familiar with the LEADER engine. I have done one valve adjustment and have had the carburetor off. I don't see any way coolant could be coming out of that vent without it also being in the oil. Are you absolutely certain it is actual coolant, or could it be just a combination of water and fuel? Coolant should be green. Ethylene glycol is hard to mistake for anything else. It is normal for liquid to be blown out the crankcase vent. Fuel can get past the rings, and, especially when it is cold, water vapor in the crankcase condenses, then evaporates when the engine warms up, and gets blown out the vent. The hose from that vent should be connected to the air filter box. At the back of the air filter housing, at the very bottom, should be a little round rubber/plastic cap held on by a clamp. It is supposed to collect liquid from the crankcase vent. Remove that and see what is in it.
