Ok here is my issue last night while sitting traffic I noticed a little white smoke blowing by the truck. I leave the light and realize that it was me making it. At light throttle it was a pretty good haze of white smoke coming outta the stack. So when I get to my buddies house I checked and the coolant level was normal so it's not drinking any, which makes me want to say that it may not be a headgasket ( which I really dont want to have to do right now). Today I left for work and it seemed to not smoke as much white almost a gray at this point but was still really bugging me ( i may have just been being paranoid at this point). At lunch today it smoked just as black as ever. Then on the way home it smoked a white like it had been the previous night about halfway home then was back to just as black as could be.... When all this started I was at a little under a 1/4 tank and this is the first tank I tried running 2 stroke oil in, Could it be that the oil and fuel did'nt mix good (maybe I used the wrong kind). I just dont know whats up. It has me kinda worried. It's an 02 7.3 with a dp tuner, intake and exhaust if that helps.

air in the fuel?

Whats a good way to go about checking for that?

What area do you live in? Because if it's in a really really cold area they will smoke white, sometimes while driving. My Ma's Superduty was rolling white smoke out of her stacks a couple of times last winter. The temps got into the sub zero -0* F. transfer to today, it started up & didn't even haze when it was fired up. It got cold around here a couple of days ago & my buddy's Superduty was smoking just a little till it warmed up.
It could also be something like a bad injector. I've seen a few trucks like that too. Put your tuner in the stock mode & see if you can notice a power diffrence. Also look for more / less white smoke. My buddy had a F550 once that smoked white so bad in stock. But when he plugged in the superchip it cleared right up to more of a black/grey smoke. I don't know if it just needed more pressure or what but we tried it twice & it worked the same way both times.
I'm just taking a guess, hopefully one of the more knowledgeable guys will chime in here.:shrug:

fill your tank up past half tank.Unless you did the prepump mods you might be sucking air.

I also agree with the cold temps also.

 

[Imjosh]

I live in Ga it's been in the upper 80's the past couple of days, But thanks.
And if I put it in the tow tune (closest thing to stock I have) It seems like there is less while smoke then when it's in the 80hp econ tune (where I do most of my driving)

I'll go fill'er up

my uncles old 2000 was blowing white smoke once to he took it in and they put a new turbo in it and it went away so that may be it

later

If the smoke goes away after filling, like others said it could be sucking air from the fuel pickup. Here is a really good right up on the prepump mods.

Hutch and Harpoon are my heros. And Guzzle is right there with them.

the only time i had that happen with the truck warmed up and 80 outside, it was bad. I had a high pressure oil line loose a oring. so the dealer told me. I lost oil pressure and the motor shut off. Oil didnt touch the dipstick. the smoke was coming from the oil running across the exauhst and burning Im assuming. took about 20 miles of 75 mph on the highway I think.

I dont think that is my issue because it still runs and drives fine and I've been keeping an eye on the oil and it still has'nt changed any

I filled it up today at lunch and have only driven like 15 miles or so since then and it's still smokin white. How long would it take for all the air to run outta the lines if it was a problem with the stuff in the tank?

Well, if you've got a cracked injector nozzle that'll white smoke out the exhaust, and then go gray at times...

What nozzles are you running? Not EDM I hope.

They are stock, Are there any other signs to look for if it was a cracked nozzle. at this point I don't really care what it is I just want to fix it.

On a side note Charles do you live in Ga and drive a red standard Cab 4x4 with the new grill and twins and all that good stuff?

 

[Charles]

Yeah, lol.

Back to your topic, if they're stock nozzles then a cracked one is about a .00001% chance, so I'd make sure you don't have an o-ring issue. Have they ever been out of the engine? The injectors that is?

 

[Imjosh]

Not as far as I know I just got the truck recently but I bought it from a friend and I know he never had them out.

The guy I bought my truck from pointed your's out one day when we were working and told me about it. His name Is Jeffrey white standard cab 2wd blah blah if any of that sound familiar or do I sound like a stalker at this point.....

 

[Charles]

lol. If you ever see me drivin around just be sure to blow my doors off....

 

[THEDIESELMAN]

White smoke can also mean low injection pressure.

How can I check that (sorry I'm kinda new to this Diesel stuff)

 

[THEDIESELMAN]

I'm not to sure how one would go about doing that with these injectors.

 

[Imjosh]

Ok today I noticed it seems like more throttle= less white smoke....When I was coming home if i was kinda low in the rpm's goin up a hill or something at 1/4 throttle it would smoke alot more than the same thing at say 1/2 throttle. I dont know if any of this will help but I just want to know what the heck is goin on here.
Thanks everyone
