Well the leak needs to be taken care of, fixed, but was the cooling system purged from the air pockets after refilling? If not, here is a video on how to purge the cooling system. The only thing with this video is put the radiator cap back on when your done topping it off with the engine running. https://www.youtube.com/watch?v=xeTgmdRkQtY

Heads or gasket not bad either. Could the radiator be clogged or a bad thermostat
Or the water pump impeller could be eroded away, needing a new water pump.

Talked to a mechanic he says it's probably the head gasket but there no water in oil. Engine runs good just over heats fast.
You would have noticed a loss of coolant, like you say, coolant in the oil, or it would be going out the tail pipe. You would notice white smoke with a sweet smell from the exhaust. A compression test would show some low cylinders if it were a head gasket. If you are not loosing any coolant, I would pull the water pump and check the impeller.
