I have a 06 mega cab with the 5.9. It just turned 33,000 on it. When I start the truck cold it will smoke white for a second then stop. It won't smoke white any other time. Should I be concerned?

your trouble might be valve giudes. i 1969 my dad bought a 1959 plymouth, wagon it had ALL the options, power seats, power windows, auto headlight dimer, 9 passenger, duel air, roof rack, we put a chrysler 392 hemi in it. my dad just loved whiping up on GTOs. and it smoked when you started it up, he took the valve cover off and about a qt of oil came poreing out. this was the old 318 poly motor. it had very small drain back holes that were cloged up and the oil stayed in the valve cover and went down the valve guides making lot of smoke. but the last year they made that style was 1966. after that they a very large drain back. so the cloged drainback is most likely not your trouble but it might be valve guide wear., or maybe seals in the intake

 

White smoke is likely water build up in the exhaust ... it comes out as steam ... check the drain hole in the muffler as it may have clogged
