    It's possible, Barbara, you have a small leak that leaks out unto the Exhaust Manifold between gaskets or pin hole when engine is hot only. Also check the oil for abnormal color, like coffee cream color, or see if you can smell any unusual odor under the hood when the engine is running verses when it is not running. If none of these works, then your next step is to have a Cooling System Pressure Test done on the vehicle.
    I hope that's help you, from JAMHS Auto
