Question about Chevrolet Cavalier
1999 cavalier 2.2L, I flushed the system thinking the antifreeze was old, but it got milky again in under 2 weeks. It has been leaking but the level doesn't go down, temp gauge has never shown hot but does move and register temp. Oil needs to be changed but it is not milky. took apart intake manifold and throttle body there is no cross over point... what could be the issue?

hello your intake gasket is most likely leaking internally into your engine.pretty common problem.the plastic and silicon gaskets get weak over time.

i think its going to be the head gasket duto the way its leaking coolant. one of the water jackets maybe i would have it checked to be sure but it sounds like head gasket

Head gasket. The reason for the cold then hot readings is the cooling system is getting gas bound by exhaust gases. A simple intake leak would just make you loose fluid, but wouldn't cause the other symptoms until the coolant was very low. Which leads me to, is the coolant full? The head gasket most of the time will not leak coolant into the oil, but instead coolant will go into the combustion chamber, and exhaust gasses will go into the coolant. You don't see any white smoke until the leak gets extreme. Then shortly after that the engine hydro locks from too much coolant in the combustion chamber. There is a tester that will test your coolant for CO gas. That is the proof of a head gasket leak.

Sounds like you have an air;lock in your cooling system.Try placing a bleeder on the return hose to the heater core ........looks like a small tap
