FE/FC 2017 fx350 Water in oil

I got water in the crank case oil. I'm trying to figure out how it got in there. My theory is though the crank case vent. I was hoping some others might have input on this.

Bad water pump seal?
Leaking head gasket?

I dont think so, coolant is at the proper levels.

How much water ? Some on top of the oil on the dip stick or the oil looks like white fence paint ?

When a hot engine hits a cold waterhole the engine cools so fast that it will suck water up the transmission vent hose out of the water hole like a drinking straw. Either run the vent higher up under the tank or in the air box or poke a small hole in the vent hose near the engine case and it won't be able to siphon water. My Italian WR250 did it twice before I figured it out.

it was a milk shake. total drained was about 2 quarts. I've haven't found that vent tube yet.

That's a lot more than I think could be siphoned. Mine was maybe an ounce of water which did turn it to a milkshake since it doesn't take much water when it's whipped up by the gearbox. If you inner water pump seal was leaking and you topped off the coolant a few times before you realized the oil was milky that would make more sense.

I thought that to, but Ive never added water or coolant to the bike.

Your 350 I think should hold about a quart and half for oil change with filter. So being half quart give or take over max level is quite a bit. It doesn't take much water in oil to make a milk shake but the quantity on contaminated oil is a real concern. Unless it was over filled with oil after oil change. I'm guessing over fill and either water pump seal leaking or head gasket. Water pump seal is easier than head gasket so I'd start there. Only other thing and this is a long shot had a buddies bike do this. After he washed it he got too much water in exhaust pipe and it found its way to oil.

Well went out for a few hours today, all is good. still not sure where the water came from
