Definition : Foamy or discolored oil or an engine oil "overfill" condition may indicate coolant entering the engine crankcase. Low coolant levels, an inoperative cooling fan, or a faulty thermostat may lead to an "over temperature" condition which may cause engine component damage. Contaminated engine oil and oil filter should be changed.
