puff of smoke?
Gentlemen,
Can someone enlighten me please. I cranked my truck (2001 Supercrew - 5.4 13,400 miles) to move it to be washed and noticed when I started it that a puff of blue smoke came out. Is this normal? Truck had been sitting for several days. I have always thought that if you see blue smoke when you first crank one up that means that oil is getting past the rings (worn ) on the pistons and is being burned along with the fuel. Subsequent starts did not produce this smoke. Worn rings with 13.400 miles? Me thinks there is something amiss. Your opinions would be greatly appreciated.

Saftrep,
Usually a puff of blue smoke at start-up, after it's been setting, indicates oil in the cylinders. The oil normally gets there by way of the valve guides, nothing catastrophic, but very annoying.
Now you’re left with a dilemma, do you live with it (most do), or do you risk Ford f’ing it up to replace the heads.
Ask around, find out, from people with engine changes under warrantee, if it’s worth it. I had 2 engines replaced under warrantee, one in a ’90 Aerostar and another in a ’90 Bronco. Both didn’t run “right” after the change, so much so I got rid of the Aerostar 2 months after the swap.
I don’t know what I would do now if my Screw started doing it, especially with only 13,400 mi. Maybe live with it for a while, see if it only does it after it’s set for several day, not just over night, and then take it to Ford 6 months before your warrantee runs out.
Good luck.

I've had a puff of blue on occasion when I look at the pipe if it's been sitting. I was worried at first but it doesn't happen all the time and she doesn't burn oil between oil changes so unless it's a real huge cloud of blue I wouldn't worry about, especially if you're running a high quality oil filter (K&N) and synthetic oil to boot.
