06 yfz, coolant in oil....HELP

I have an 06 yfz quad i recently bought. I did the oil change and replaced the coolant with engine ice. I rode for about 15 mins and it got hot and stalled. Got it started and smoked blue like crazy. looked in the oil resivior and it was really watery, not milky but watery. tore the top end apart and the two head bolt under the cams were hand tight....great! thought it was the head gasket, replaced and no such luck. started it again and no smoke but after it got hot and cooled the oil res was full again!!! got new water pump seals but have not replaced yet. the old ones didnt look too bad but i need a gasket first. head and jug look good, no cracks, and im gettin real frustrated with this damn quad. PLEASE if anyone has any idea let me know. Thanks The quad does run and start great just cant figure out why theres cooland it the oil, i did drain the coolant and it looked a lil dirty too. but nothing was milky

put a presure tester on the cooling system with the spark plug out. If it's the head gasket the coolant will come out of the spark plug hole. If the cylinder stays dry it's most likely the waterpump seals. I'd replace the bearing that the impeller shaft rides on while I was in there as well.

I did repalce the head gsaket and all the top end gaskets and still did the same. I have the clutch cover off and am ion the process of replacing the seals but the idiot who rebuilt this before i got it never put the washer inbetween the impeller and shaft so i have to order one. just lookin to see if there are any other possible places water can get in.

Are the seals in the correct way? If I remember right they are positioned opposite of each other spring side away from each other. It's not an uncommon failure. I would suspect the waterpump seals before the head gasket for sure.

dont use engine ice for coolant use half coolant and distilled water and check your water pump seals
