Thumbs down Milky oil, loss of antifreeze

I have an 04 yfz. It just started leakin antifreeze into my oil. I have no visible leaks. I know it could be either my water pump seals or a head gasket. If its a water pump or oil seal shouldnt I be getting one or the other out the seep hole? This is the first time I've had this issue with this wheeler and have no idea. Any help is appreciated.

sounds more like a blown head gasket

There are 2 waterpump seals. It would be the back seal that is leakin on yours more than likely. The back seal seals out the oil from getting into coolant

If the oil seal is bad wouldnt that allow oil to make it to my seep hole?

It could also be a headgasket but it is alot easier to pull the water pump apart than the head to find out where the problem is.

I have my water pump apart and the outer pump seal out. How do I go about getting the impeller shaft and oil seal out?

A cracked cylinder should make it run like crap though. Mine runs great with the exception of gettin antifreeze in the oil.

Highly doubt its your water pump seal because there is an oil seal behind it and even if both seals failed coolant would never make it into your lower end because it would all drain from your wep hole in the pump. Blown head gasket is possiable but also could be the o-ring between your clutch cover and case half just above your counter balancer gear. Its the size of a nickel and has a dowl pin through it. The heat causes this o-ring to become brittel and crack.
