Deceleration, tons of white/grey smoke

[slednecks03f7]

I have a 2000 F250 stock except 5" straght pipe and edge program that was in it when I bought it. turned 150k a month ago. I have had the truck for 1.5 yrs and 20k miles.
My problem that has been getting worse is the truck is smoking alot on decel. Only smokes when the truck is up to operating temp. Started about a month ago with a little smoke here and there but now whenever I drive it does it every time. Example, when I get off the highway and pull up to a stop light or stop sign, like I said the truck has to be at temp but no matter how long or short the drive it will do it. As soon as I lift off the pedal it starts but when at a complete stop the smoke catches up to you and has been "flooding" entire intersections. Does not stop smoking until I drive away and it quits. The engine does not have a miss, have not noticed loss is power. My fuel milege is down. Im in MN so temps from 40F-0F. Oil has about 3k on it and the fuel filter was changed then also. I just put a new air filter in. I only drive the truck about once a week or for weekend snowmobile trips. I am not burning oil, not burning coolant.

100% only smokes on decel.

where do I start?!

hmm... I have not tried this test on a 7.3, but I use it religiously on the 6.0... take out the fuel filter, key on til the bowl is full, make sure you drain it first to get all the gunk out. with the bowl full, make sure key is of and jumppower to starter, looks for air bubbles...

this sounds like coppers on the end of the injectors...

Turbo, mine did it for about a week before the shaft broke, actually rebuilding a turbo out of a 2000 that had the same problem. Pull intake and check play. The oil usage wasn't noticeable until it sent the turbine wheel into orbit, and coated my whole exhaust system

I hope its not the turbo....I will check play tomorrow.

Rebuild is cheap if you do it yourself, and fairly easy, hardest part is getting the up-pipe and down-pipe clamps off. A air hammer with a long bit works great, rattle them a bit and they usually release

[slednecks03f7]

ive had the turbo off last spring, i agree those clamps if they have not been off since factory are not fun.. I had a bad oil leak from the wastgate valve. huge surprise to find an updated ford part # to fix the problem... ha

Where do I even start with a do it myself turbo rebuild? (if thats the problem)

I get my rebuild kits from Ron's Turbo on eBay, great customer service

[slednecks03f7]

well i will check the play in the morning. Your right, rebuild seems simple.

So I cold started it today, started normal, no miss, idles smooth as always, no excessive smoke ect. If it were bad injectors I would have problems that I dont have correct? Had not ran in a week, not plugged in, temps yesterday were single digit and started this am around 20F outside air temp.

I also pulled my air intake off to get to the turbo. Impeller shaft can move in and out about 1/4 inch. it does not move any other direction, no obvious damage on blades or anything.

I'm still betting on the turbo, it won't smoke until its up to temp, and that seems like a little to much play.
