How does the truck run? Smooth idle...good power...starts easy? Does it smoke all the time, cold and warm engine temps? Your coolant condition should be monitored, make sure you are not losing coolant and having to add any coolant. Keep the coolant level at the minimum line or just below it. Your white smoke condition could be(EGR valve or EGR cooler related, or a constant leaking fuel injector issue).
You can pull the EGR valve out(2-bolts hold it in place on top front of intake manifold-see the 6.0 bible in the stickies section at the top of this forum for locations) and check down inside the intake manifold hole where the valve comes up out of, and if it's sooty and dry, then your ok, just clean the valve and vacuum out the hole. If it's wet down inside the hole, then your EGR cooler has failed.
