bump for some help

 

Are you sure all 8 injectors were new?
Was he certain he installed the copper washer?
Are all the o-rings (2 for each injector) good on the injectors?
Did he torque the injector hold-downs to 24-26ft/lbs?


Really there is very few things that could be done wrong. If it was the injectors sleve it would have smoked prior to the install of new injectors, unless he damaged them pulling them out. Ask those 4 questions and let us know.

 

He swears every thing is right so yesterday morning we took it out driving, it didnt smoke for about 5 minutes then it started to smoke white real lightly. We kept driving and it eventually cleared up we ended up putting like 50 miles on it with no problems, they took it on a job today pulling an enclosed trailer close to 100 miles and it ran great. The only thing I can come up with is maybe the cat had some fuel in it from when the injector wasnt seated and it finally burned it all out. I have no clue if this is possible or not. But so far all appears well. Thanks for your help!

 

Sounds like exactly what I would have suggested. Just keep running it, and run it hard. It needs to blow out all of the unburnt fuel that poured in there while the injector wasn't seated properly. Good luck!

i can' t believe i didn' t think of this, but anytime you replace injectors on a 6.0 or 7.3 powerstroke, you get air in the high pressure oil system. it takes about 30 miles of driving to clear up. glad he figured it out

 

If you dont mind what does it cost for the injectors and how difficult is it to replace them?Thanks

 

Stock injectors I've seen range from 350-500 bones in the parts department. Replacing them is quite a simple task, but can prove to be hazardous if proper procedure is not followed. Trust me, it's bit me in the a$$ before. All new in box 6.0 injectors I've seen come with all 3 o-Rings and copper washer installed, so just make sure their good before you put them in. Torque to 23-24 ft. lbs. Make sure your stand pipe is seated back into branch tube, as later builds can become dislodged during assembly. Place your oil rail back on top of the injectors, and GENTLY push to seat into injector bodies and down onto rocker carrier. Torque to 10 ft. lbs. Depending on bank and build, fill the oil rail back up with new oil, either from the tiny plug on top(takes a 4mm hex to remove) or the ICP sensor hole. This will usually take 1/2 to 5/8 quart then complete reassembly. Doing this will aid in air removal, ease starting after repair, and should begin to run smooth within a few minutes just idling in the shop.

 

Man i just had the same thing happen here at the dealership, I put 2 in a 06 and one of them just decided it wasnt good enough and dumpued raw fuel into the cylinder...eventually causing it to shut down and almost hydralock.
So it happens everywhere.

 

mine is doing the same exact thing so im guessing I need to pull it down and check all injectors? it boiling out white smoke so thick you can hardly see through it. started as a light haze went away and then came back heavy once i began driving it. know it seems like its hydrolocked

My problem was also compounded by the injector being stuck in the head and needing some major coercing to come out.

 

Might be coolant into your cylinders from the EGR cooler rupturing or head gaskets... What are your deltas?


Also for anyone asking or wondering about injector prices... Get some Warren 155 injectors for $500 for all eight and they will treat you much better then new oem ones... And they are a lot cheaper:nod:

 

If it still has the egr cooler that would be my first guess.

 

well you could definately damage your cups by the injector bouncing around if not torqued correctly. you also could have let combustion gas in to the rail causing the injectors to wack up

 

I've had quite a few customers who have replaced all of their injectors when they buy a new engine and have problems with them. About three months ago we had a Ford Dealer in South Georgia claiming that there was a problem with our engine. He had put all new injectors in to start but it showed symptoms of a bad injector so he replaced it and still had the problem. It took some convincing but we talked him into replacing it again. The third injector was good. Since then we've seen it two more times with new injectors.
We called our local dealership yesterday after another shop had a problem and talked to our parts guy. He said that Ford is selling new and re-manufactured injectors, both in the same box with no reference to which is which.

 

they usually will say remanufactured on them. haha you just have to look at the fine print ha! right under the hecho en mexico *shakes head in shame*
