It was over heating boiling out of the overflow I change the thermostat and one of the motor mount know the oil looks milky should I change the oil

if the oil is milky,then you have more than a thermostat or motor mount problem.over heated a little to much,sounds like.have qualified mechanic check it.

First..yes,change that oil. Milky oil is most likely coolant in the oil from a blown head gasket. The Camry 4 cyl engine is VERY tough and can usually handle an over heat or two. However if it really cooked you could have a warped head and blown head gasket and more.
