almost out of warranty HELP!!!

[msbrpower]

Hey guys, Im a 7.3 guy but my brother just bought an 05' with 99000 miles on it and it smokes white. Not all the time mostly on start up when it is colder like 50 degrees. but it has done it a couple time when it is warm driving down the road. He took it to a dealer and they said nothing is wrong at all. Any ideas??? Its almost out of warranty help!!!

if it just does it when its cold and it is just started then cleared up thats just a normal vehicle thing? when its cold they blow white smoke until they are warm? my truck usually does it the first mile or so but thats it. idk why it would do it going down the road. a 6.0 guy will chime in soon
