Emissions and Exhaust Systems

If after you take off from sitting at a light you get smoke from the exhaust but it goes away could this be the valve?

Most likely the valve seals. They allow oil to seep into the cylinder(s) when idling. After you accelerate the oil is burned and the smoke stops being visible. Chrysler 3.0 engines are famous for this, watch some Chrysler mini-vans at the stoplights.
