Gator 6x4 with water in oil

Hey Guys, first post here and I apologize if its in the wrong place.

Ive got an older water cooled kawasaki powered 6x4 gator that has got water in the oil and of course google searching turns up almost nothing helpful.

I found this forum and am crossing my fingers its not just for the newer stuff...

Anyway, if anyone has a direction to point me itd be appreciated. I dont know if its just headgaskets or something else, I dont have manuals... just nothing ha.
