Well i'd change the oil and drive it around a bit man......
Might have been a fluke thing........
it won;t hurt to run it like that just keep the oil changed and coolant full.......

 

yeah coolant full and watch your engine temp.....oil turning milkey, and half full radiator....youve got a blown gasket....that sucks, the wooshing noise could be losing compression??? because of the blown gasket, but your definitly pouring coolant into the engine.
