Grey smoke?

i have a question for you all, its not for me, but the father in law, hes got an 04 6.0L and today on the highway he was crusin with the cruise control on and he said it started to lose power for no reason, all the stock gauges looked fine (he has no mods) and then he looked in the rear mirror and saw white/grey smoke coming from the pipe. he pulled over and and left the truck idle, got out and it was still smoking, and then it went away and he carried on down the highway and everything seemed good. so any ideas??

My 1st quick guess would be the EGR valve. Any other symptoms, CEL come on?
