2010 4.3L puff of blue smoke

[canadianhunter]

I have a 2010 GMC WT that after it sits for 2-3 days it puff blue smoke when starting. Goes away quickly, Has anyone else had that problem? What could be the case of this?? Valve seal?? I have heard of this in motors with some miles on them but i noticed this with 15,000km but i have to busy to take it in to have it looked at. Any info would be helpful so i can discuss it with the dealer just one of the many issue that has happend with this truck...Thanks
