I have an f250 '05 blowing white smoke. The harder I get on it the more it blows. Took it to ford for diagnostics and they had me replace the egr valve. $400 later still white smoke! They said the injectors are fine according to the computer and that there were no signs of headgaskets issues.

The only thing I have not checked is the turbo seal. Any other ideas?

 

When I had that problem it turned out to be the injectors.It got worse real fast.I believe it was 5 total,but since it was on both sides I replaced all 8. Good luck.Maybe your problem will be different.

 

How did you determine for sure that it was the injectors? Is there a test that ford should have done?

Do you have a recommendation on where to get injectors? Brand?

Thanks!

 

Have you seen these two TSB's?

06-2-13***WHITE SMOKE, LACKS POWER, EXHAUST ODOR, SURGES, RUNS ROUGH, OR NO START - 6.0L


06-22-3***WHITE SMOKE, LACKS POWER, EXHAUST ODOR, SURGES, RUNS ROUGH, OR NO START - 6.0L

Don't know if it's related as these seem to be more cold start oriented.

 

White smoke, your injectors are likely bad. All Ford's computer can determine is if they work, not if the needles and seats are bad, causin the injector to leak. Leaky injectors wreck pistons.

 

But is there a way to test that?

 

Also, would the truck be running rough?

 

Probably you are getting enough fuel dillution to make up for the minor oil leak past the turbo seal. It will worsen over time till it is obvious. Nasty motor oil can wreck havoc on the injectors. Regen like condition can also happen if the turbo is frozen from crud exhaust boosting increase psi with rich fuel mixture. It just depends on where the turbo vanes freeze up. Do you have evidence of oil/contamination in your intercooler? The minute I see white smoke and a diesel I think Regen or a lot gasoline mixed with the diesel fuel.

I just spoke with the Dealership and the Mechanic, they said they did a buzz test and balance test. Neither test showed signs of a bad injector. The only recommendation they had for me was to drive it until one failed, or replace all 8. <o></o>

If I drive it until one fails can’t it severely damage my engine, they said that it would just lose power and want to stall. <o></o>

Thoughts? Suggestions? <o></o>

 

Had to read and notice the year and the 6.0. Turbo vanes stick and raise the boost, causing your poor stretch bolts to yield. Given a combination of too much fuel from an injector and higher than normal boost, passive regen the nasty white smoke until it is cleared in the exhaust. There is a peculiar thing that happens with the EGR, higher than normal turbo boost, and excessive fuel injection or injection psi too high. Is the oil dilution a little higher also? There are a lot of after market goodies out there for this engine to better it. Obviously if the condition exists perty much all the time passive regen is happening constantly when it heats up the exhaust due to higher turbo boost. In normal regen of a newer motors after 2008 the back 2 injectors are the ones that do the excessive fuel injection for Regen using extremely high fuel injection pressures.

What commonly happens for your motor is the copper injector to head gasket on the injector fails and combustion gas finds its way into the HP fuel system. This burns out the o-ring sealing oil. The gas bubbles then are headed down the injector blowing excess amounts of fuel into the cylinder creating the nasty smoke out the tail pipe. Let go you will be in for a lot of expense. Change them now and oil and filter. Also injector pump recommended.
A reman injector is just as good as a new injector. I would call around to another dealer to verify your local area. If they are both high, buy on line, like from fordparts to search. There are core charges so you return the old back to them.
Just thinking in print.

 

I am not aware that the 05's have regen. From what I have read that is 07 and later.

Is that true?

 

Sorry earlier I did not get the second half of that message. Are you recomending that I change all 8 injectors?

 

I found some injector o-ring kits that you can buy. Wouldn't that be the best way to proceed? Save some money and get a good look at all the injectors.

6.0L Injector Seal / O-ring Kit

Let me know, thank you so much for your help!!

 

Remanufactured injectors start at $186.79 each at rockauto.com, with a $175 core charge.

 

It is the copper gasket sealing the Injector at the head from combustion gases that leaks combustion psi back into the fuel system HP manifold. This causes the over injection/ dilution hydrolocking damage to the cylinder or fuel system many times. Recommending rebuilt injectors is if you have injection problems, too rich. You can replace the ones you find bad but not so easy to detect, usually a bore scope can see more when injector is removed. The o-rings seal the fuel/oil psi to the injector. The rebuilt injectors come with the copper gasket installed. It is a one time-one use gasket. If you have below specs fuel psi it is time to do the pump also.

Watch all of master techs videos after the 1st one. The info is great even if you hire it done.
