Re: 2005 jeep Charokee laraedo sports edition 3.7 liter 2wd
Its really hard to say for sure, but sounds like possibly a head gasket issue?
Are you sure its oil? Its really hard to say for sure without being able to look at the car, its really just a shot in the dark. The coolant overflowing could be from the overheating or it could be from combustion chamer pressure reacing the cooling system and pushing coolant out of the overflow. Still doesnt completely explain the oil though.
