What do you mean by burns oil? Smoke out the tail pipe? If so, what color and how heavy? How much oil are you burning in how many miles?
And last, but unfortunately not least, with that K&N, inspect the intake tube for any signs of dust or dirt. Then check the intake wheel for signs of dusting. Then check your blowby for any signs of pressure.
Here's to hoping that K&N didn't dust another engine.
I have the exact same thing (2001 F-350 6-speed), and mine started doing this recently, but only right after a cold startup. I'll back the truck out of the garage without using any go-pedal, then when I give it a bit to get out of the driveway I let off the pedal. It's right after I let off the pedal that a large puff of smoke comes out. I don't see it at all on acceleration, just when I let off......and only does this at first cold startup. After a mile or two down the road, I don't see it anymore. When it's real cold out the smoke is blueish white, when it's fairly warm out the smoke is darkish black. After a warm startup I don't see it at all......just that first cold startup every day.
Any ideas? I never see a drop in the level on the dipstick.

I have this problem right now. I have been towing my fifth wheel for the past few days and I started blowing white smoke, but only on deceleration. I have ran diags and nothing comes up. I did burn a little oil, but only about two or so quarts. I ran the buzz test, cylinder contribution and just a regular KOER diag. Nothing came up with it. I have not lost any other fluids, but my fuel mileage went down the tubes. I was thinking maybe I got some mixed fuel at one of the truck stops along the way and maybe got some dirt in the injectors. I also put in some diesel clean today, but have only gone through half a tank. Any suggestions?

There are 10 types of people in this world; those that understand binary and those that don't.
Shelby, does the smoke smell like burnt 15/40 or raw diesel? Try running without your tune and see if smoke goes away. If you bent push rods do to cold weather shut down, ditch the straight pipes! Just put something in there to keep the cold air from rushing up the pipe and f-ing up your valvetrain. On that note, if your pushrods got bent, you had some valve bendage. It may not be bad enough to run bad, but could have worn out seals on the damaged valves. I had this happen on my 68 390 coug with open headers in winter.

I found out what it was, it turned out to be the turbo. There was almost an inch of in/out shaft play, but you could only feel it if you gave the turbo compressor quite a little "tug" in and out. The side to side, there was absolutely zero play.
Got a new Van turbo on the way
I really doubt the valves had bent, the truck was running awesome and was even spooling the busted turbo no problem, no difference than before. I had one Powerstroke that had over 850,000 km's, and it bent a couple pushrods in cold weather once, replaced them, never happened again.
If the valves were bent, I would imagine they would have bent the pushrods again in the 300,000+ thousand kms the other truck saw, or the 15,000 this truck has seen since it bent the 2 pushrods.
Thank international for the mesh screens on the intake to keep turbo parts out of your valves. So how did your valves get bent, cold air?
