Depending on the shade of blue, it could be air in fuel or even anti-freeze. Are you loosing water?

It sounds like anti freeze or oil you could have bad piston rings. Since that is very high in MILES the piston rings could be getting worn. If it just when you start the truck that it puffs blue smoke its probably ok the piston just needs to warm up. But check your oil and anti freeze.
