Question about 2003 Ford F350 Super Duty DRW SuperCab
Black smoke is a sign of an overly rich fuel/air mixture. White smoke is a sign of coolant entering the combustion chamber. Most likely you have a blown head gasket. Other symptoms are loss of coolant with no apparent leak, loss of power, miss, oil level overfull, a white foamy substance on the underside of the oil fill cap. Stop driving this truck until you find the problem. Driving it with a blown head gasket will destroy the engine. A compression test will verify this.
