If the engine isn't running hot, you may have a bad head gasket. If pressure from the engine gets into the cooling system, it will blow it out. When the engine is cold, remove the radiator cap and start the engine to see if it blows coolant out. If it does, check engine compression to see if there is a low cylinder where the problem could be.
