7.3 white smoke
Hey guys my 2000 f350 7.3 is acting strange lately. Its got 252k and is all stock other than exhaust,intake,ww2. It smokes white every random once in a while for some reason. At start up it wont though. If i get on it every once in a while it will smoke white then go to back to black. Im not consuming coolant, and the oil looks fine, no residue on the oil cap and its not puffing out the oil cap either. Other than that its running great just dont know why it goes white every so often.

Possible fuel pump issues. I have had issues with mine before, mine just died though and had no power and smoked white. Injectors were pulling fuel from the tank was the speculation. Getting fuel pressure would help ruling out that.
Others will know better though.

The engine may have one or more bad injectors, retarded injection timing, Low compression, and Air in the fuel system to name just a few.
A few questions your way:
Q: Have you had, or know of any injector work? How long ago?
Q: Do you have a Chop/Programmer? Have you tried a week with out it?
Q: Do you have, or have you noted any change in:
a. Fuel Mileage?
b. Oil Consumption between changes?
c. Rough Starts?
d. Rough Idle?
Q: Filters:
Fuel - How many miles?
Air - Clean?
Lastly, Do you have a Scantool capable of bi-directional communications?

White smoke, visible after the engine has warmed up could be a number of things. I don't know of any that are are something to look forward to troubleshooting or repair. But, hopefully we'll discover something not so bad.

Ive had the truck for a year and a half i havent done any injector work. Im not sure if the previous owner did any work on them. I dont have any tuner or programmer. Fuel milage seems the same the truck is a xl model so i dont have the fancy mpg reading. Its not consuming any oil. No rough start,no rough idle. I change the fuel filter at every oil change. And air filter is clean. And i dont have a scan tool but was looking at some so i can maybe run a injector buzz test and a compression test but not sure which one to get since i dont really want to spend a crazy amount of money on a scanner. I heard there are some that are about 60-70$ that connect to your phone but not sure which one will run those tests for my truck.
Probably a leaky valve stem, seal, Injector, etc..

Have you heard of the new archoil treatment that you put in your oil and fuel and it lubes up the injectors from the fuel and oil side? Ive heard good things about it. Maybe try that if its nothing major and it might help a little?

Check out your turbo. I've seen that a lot in Semi's. Seems that there is a little seepage of oil going into your turbo causing that.

I could also be a CPS, I would keep a spare and the tools to do the job in your glove box. When it smokes white, does it seem to not have as much power or misses any? If anything, I would still be looking toward the fuel delivery side of the house. White smoke on this motor to me indicates a problem with fuel starvation.

If it is the turbo leaking it will be the bearings themselves, not an o-ring issue. A scan tool will not do a compression test either. Torque Pro is the Android version of a scan tool that you will need an wireless blue tooth adapter to hook up to the OBDII port on the right side of the drivers dash down low by the accelerator pedal. If it is very white smoke, I doubt it is turbo though. I concur it leans to a fuel delivery issue.

Melendez7.3: I don't have the knowledge or experience to help you, but I can ask some questions which may help other people help you better.
I wonder if you are getting a P1211 engine fault code? You are in Florida? Post your area, there are great members in Florida, who if you were to drive over with beer might run an AE or NGS code "reader" on your engine for you.
I also wonder if you were to take the fuel filter out, evacuate your fuel bowl, leave the lid off, and had someone turn the ignition key to on (not to start) how many seconds it would take for the fuel bowl to fill?
You may want to replace your fuel filter with a new one just for fun. Also, F_250 (Pete) verified that there is a nonservicable fuel screen inside the frame rail fuel pump, and of course if you haven't personally done the Hutch mod, you need to drop your tank and inspect the fuel pickup screen and mixing screens and fuel pick up foot (and consider doing the full Hutch Mod at some time). But scan the engine for codes first. And maybe do the empty to fill count on the fuel bowl and post your results here.

Not necessarily. There are bearings that do contain the oil and oil is also pumped thru your turbo too to keep it cool.
You might try this:
1st: Start your truck when engine is warm.
2nd: Rev Up your engine to max RPM and let off.
3rd: Repeat and Listen for sputtering.
4th: Look for the smoke also.
If the sputtering is excessive it would be the Turbo.
What your saying is you have no loss in power when driving when this is happening and if fuel was an issue you would see and feel some performance issues, but don't rule that out.
Also see HKusp post too.
