Losing Coolant

I have a 700Sportsman and it loosing coolant somewhere. No water in the oil no visible leaks no smoke and a compression check turned out fine. Anyone have any ideas? It has to be going somewhere!

Question

Thought I was loosing coolant out of the T where all three hoses come together so Idouble clamped them but didn't solve the problem. The machine gets used daily and parked indoors on concrete,and have yet to see something leaking.

Just got home and checked oil and its milky. It was clean last week but I either I overlooked it or finished it off last time I used it. So what do you think, Head gasket or cracked head? A
