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

Tried that already.

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.

I have a Crack in my intake and cold water leaking from the radiator.

My exhaust smells like gas need new Or sensors which I already knew but no smoke and no coolant smell water pump it is
