Default Water and oil coming out breather

My bike has developed a new problem.
It seems like after a decent ride a mixture of water and oil come out my breather (which is routed to the air) and I find a small patch of the mix on the ground the next day or so.
I looked in the oil bag and oil seems fine (no water mixed in) so I'm kinda baffled where the water is coming from.

Is that the umbrella valves???

water pump / heater core

on the real side its the moisture that develops because of humidity in the top rocker boxes and that turns to milk and yes it spits it out < I am not going to say it

Is there a fix?
If the humidity is getting in my rocker boxes does that mean air is getting in from somewhere?

FWIW there is no oil leaking out of my rocker boxes.

I only ask 'cause this is a new thing that hasn't happened before.

My catch can catches a foamy mixture that looks like cafe mocha. So, it's water mixed with some oil.

Maybe your oil level is too high, causing more to come out the breather.

Why can't you be normal?

Pull the hose off from the head breather crossover and see if the foam is in the top of the hose, that will tell you if it is just in the bottom of the hose only and don't worry about it.

If those umbrella valves are messed up she will pump much oil out the hose and oil your bike

When you say breather - from the rocker covers to the air filter or dripping from the air filter cover? I'd say condensation in Covers or filter cover.

couple of things - if you have a plastic breather you should replace it as the plastic will and does chew the breathers hole up - my 1926 JD has its one and only breather valve in it as its metal

the foam is a normal part of owning one of these machines --------- or maybe its this
