Hi there:

The fact you noticed milky oil is an instant indicator that you’ve got a major mechanical issue where coolant or water is entering oil galleys. Even if the engine doesn’t overheat, you still might have a crack in the cylinder heads or damaged head gasket. If this occurs, it can create excess pressure inside the motor and cause it to shut off. Before you continue driving this vehicle for extended periods, you should contact a professional mechanic sooner rather than later to complete an engine is hard to start inspection. This will allow them to diagnose why you’re Sebring is having running issues so that the right repairs can be made.
