White Smoke
 

When i first start it it does smoke alot, but it will still rev up fine! after its warmed up a little bit it revs up fine untill you hit about 2000 rpm and then it just starts dumping out white smoke and will hardley reach the rev limiter. Please help its REALLY bugging me!

Sounds like a problem i recently had a couple months back.

sounds like you have an injector hung open. any skip or roughness when running?

There is a video on youtube that is exactly what is happening its called "Powerstroke smoke and no power... HELP" its a shot of the exhaust on an obs powerstroke.

ok wow that doesnt look good. crew cab like mine haha

anyways it deffinetly looks like your having a fuel issue, how many miles on the truck?
i had this similar problem, it turned out to be an injector nozzle stuck open, slowly leaking fuel into the cylinder. do you know if they're the original injectors or have they been replaced in the past?

there are about 240,000 im not i got the truck from my grandpa about a year ago and im not sure what he did, he took it to the shop about a month ago and they replaced some glow plugs and not sure but i think they might have gone thru the injectors. Anyways the guy on youtube said the his problem was the fuel pump bad and letting air into it or something like that.

It was doing this before we took it to the shop, we took it to the shop because it wouldn't start with out a shot of ether.

ok so 240k on stock injectors.

If your fuel pump was leaking you would see a puddle under it when its running, it would leak out of the small air vent hole on the pump casing. its a diaphram pump that runs off the camshaft in the valley under the intake manifold. if that were the case it would take longer and longer to start up because you'd be purging the air out of the system. how long does it take on average for it to start?

Well i let the glow plugs cycle and just a few cranks maybe 3-5 seconds on average

Its not haveing trouble starting after we took it to the shop. They said some of the glow plugs are bad..

so really it starts normal?

White smoke means either raw fuel, or coolant. 7.3's dont usually have head gasket issues, very uncommon. but a cracked injector sleeve would allow coolant or fuel to leak into the cylinder. but usually give you some major running issues like stalling and hard skipping.
IMO i think you just have an injector going out, 240k on original injectors is pretty damn good, could be time for new ones.

Ok ill check it out! I thought that the ford shop went through the injectors but maybe not!

Do you have any idea on how much that would cost?

Smell the exhaust... Fuel will burn your nose, coolant will smell sweet.

I would bet you have a broken injector nozzle or a lifted injector. Stop driving it, if its fuel its going to destroy what ever piston is the problem!

Thanks but how do i fix that?

Fix what?

You dont know what it is yet...

If it smells like fuel its injector or compression related. If it smells like coolant then it could be many things.

Time to get it scanned.

i found the best way to find these was with a cylinder contribution test with a scanner. and my recommendation, if it comes up with more than one bad injector, you should do the whole set of 8. yes its expensive but trust me you wanna nip this in the ass ASAP.
if you bring it to someone to have it checked out rather than doing it yourself, have them check out the valve cover harness's and all the wiring. i've found wiring issues in these wont necessarily throw codes, causes headaches haha.:pca1:

I miss my OBS 7.3, even with new injectors it would puff white until it was warm...but holy s**t that truck would haul a** when at temp!

By the way a full set of new injectors can run about $2200 to $2500 big ones :argh:
Re-man's are cheaper but will not last you as long, most dont even get re-manned, they're tested and if they test good they just get sent out. so i dont have much faith in that.

If you're gonna get re-mans, get bigger sticks, that will at least tell ya they had to tear into them to mod them. And if it's a respectable company, they'll stand behind their product.

Ok and will a stuck injector cause the reading to say the injector is faulty? I havent gotten it scanned yet but plannin on it when i get time:argh:

No it will not. To have an injector code it really has to be electrical, you'll have and injector circuit open or circuit closed code if it is electrical, but those throw check engine lights. a stuck nozzle or something like that isnt detectable, probably in a worst case senario it would throw a fuel metering code because of excess fuel going through the metering valve.

trust me, my crew cab has 290k on it now, its been through one set of injectors already and i just had to replace 2 recently because of this exact problem, i had a crack in one solenoid pack on top of one injector, which messed that up because of oil entering the solenoid, and the second injector nozzle was stuck open causing your problem that your having now. :tu:
If i had the money, i would've gotten the whole set replaced with stage 1's. but i dont have 3 grand haha

Wow this thing has really been a pain! im kinda thinkin it also might be the feul pump? Because i went out to start it the other day to see what the exhaust smelt like and i cranked it and no start. Let the glow plugs cycle and no start did this several times until the battery died. Went to jump it and the starter wasnt working right. It was a bad connection. I Tested the starter earlier today and now i need to clean it up and install it. So i have yet to smell the exhaust! But prior it had been takin a little longer now that i think about it!:argh:

yea deffinetly a sign you have an nozzle stuck open, air is getting back through the system, meaning you have to purge all the air out before it'll start, that was one of my symptoms too. if you think its your pump, you can check the pressure on the side of the regulator with a guage, looks like a bicycle tire valve on the side of the fuel filter housing, should see somewhere between 30-50psi of pressure. do you know if you have a diaphram pump in the valley of the motor or the electric pump on the frame rail? if you have the pump on the motor it needs to be running or cranking in order to check. :pca1:

Yea but now when i go to start it it just clicks once and wont turn over! This is definatley a problem child!! haha:argh::dang:

I am just now getting to go get my injectors looked at, but first has anyone heard anything about Hot Shot Secret? If so what have you heard? Good, or bad?

Please explain to me how a PSD injector can have a "stuck nozzle"...

valve inside the nozzle isnt closing....
if this is the case you should be able to take the injector and plug three of the four holes of the fuel inlet's. put compressed air to one of the holes and watch fuel seep out of the nozzle.

not the most high tech way to do it or the right way but it works.
