If it's cold (below say 50d)where you're at then yes, it's normal.

If you are talking about a quick puff at startup then goes away, mine does it to, but only when the truck has been sitting for a while. It doesn't use oil so I don't worry about it.

Valve stem seals more than likely. They are letting a small amount of oil into the cylinders when sitting.

I have a 2002 4.6 F150 that smokes oil smoke on warm start up, doesn't seem to be a problem on cold starts. 35K miles. Only had it a couple months, not sure of oil consumption.
