Puffing smoke, or a consistent flow of the oil vapor?

Not good.=Hole in piston, bad rings, o or other wise something that will allow combustion pressure to leak past the piston and into the crank case. Rebuild time!

How strong of a puff? If you put your hand over the oil fill tube to cover the hole, can you feel pressure? If you turn the oil cap upside down on the fill tube, does it blow the cap off, or does it just vibrate off?

Hopefully Kris is wrong, but if you've got pressure coming out of the fill tube, then see above.

White smoke is unburnt fuel... (broken injector, bad piston, bad cylinder wall, bad ring, ect.) Since its "puffing" that would point towards a piston related issue like Kris (strokin_it7.3) said. Go get a FULL compression test done asap...
