I drive a 1989 GMC Suburban 7.4L 2WD with towing package. In the last month it has started smoking only after it is warmed up and I have come to a complete stop at a stop sign or a traffic light, when I accelerate I get one large cloud of white smoke. It does not smoke when I'm idling or when I'm driving.

In the past month I have replaced the transmission pan gasket, the PCV valve, the oil sending unit, the transmission to radiator lines, plugs and wires, valve cover gasket, the oxygen sensor, the oil cooler lines and the clutch fan motor. The cylinders were checked for compression, they all have at least 150 lbs. I also changed the oil and filter and added a quart of Lucas Engine Oil Stabilizer.

All the above work has solved my oil leak and transmission fluid leak, but I'm still smoking. Perhaps wise minds could point me in the right direction. Thanks for any help.
