Cloudy Radiator Coolant (After Flushing)

That's interesting... could that be caused by the head gasket or could it be something else? Also, if the radiator cap is off during engine warm up, should the fluid stay at the same level, or would it jump out during each rev? When I was performing the radiator flush, that's how I noticed the leak in the timing cover was by revving up the engine. Every time I would move the throttle, it would spew out. I appreciate your help
