I know there are many post on here about white smoke/ smoke in general but i havent seen one excactly like mine.
when cold it will smoke bad whitish blue smoke untill warm then goes away. when it gets warm just sitting in the yard hitting pedel little hard a puff of white smoke comes out every time this is in 90 degree weather and warmed up all the way. i have have took the programmer off of it and still does it just bought it 2 weeks ago and its still runs strong no skip to be noticed, and just changed the oil a week ago also.
please dont let it be the engine
ran codes nothing on codes except what they throw with a programmer on
2001 7.3 psd
182,000 miles on it.

 

Someone will have a direction for you to go...

 

With 182,000 on stock injectors....I'd say either one of them is leaking down internally, or has an external o-ring seeping.

 

i smelled the smoke and it doesnt smell sweet it gotta be fuel

 

White smoke is un burnt fuel... White smoke w/ a tid bit of blue is un-burnt fuel with some oil in... Sounds like an injector issue to me. You want to do a buzz test on all the injectors and make sure they are all working up to pace... If it passes that then you should look at an o-ring issue... Could be your IDM (injector driver module) also but i would think that if it was that you would notice it...

 

FYI on the smoke:
Smoke analysis

White smoke:
Caused by unburned fuel passing through the engine. Some white smoke is normal on cold start-ups.
Excessive white smoke could be an indication of inoperative glow plugs, loose injectors, low compression from worn rings or bent connecting rods, or coolant leak into the cylinders--head gasket or injector well sleeves.

Black smoke:
Caused by excessive fuel for the amount of air drawn into the cylinders. Some black smoke on hard accel or at higher altitudes is normal.
Excessive black smoke could result from restricted intake or exhaust, inoperative leaking or weak turbo, intake hose(s) leaks, leaking or worn injectors, fuel return or supply restriction, stuck Exhaust backPressure Regulator valve or solenoid. Also PCM inputs such as BARO MAP ICP or EBP sensors.

Blue or blue/white smoke:
Caused by insufficient fuel or oil consumption. Normal when engine is cold or idling for extended periods.
Excessive smoke could be caused by air in the fuel, contaminated fuel, loose or plugged injectors, worn or leaking injector o-rings, thermostat stuck open, oil consumption, or plugged crankcase depression regulator valve. Also PCM inputs such as MAP or ICP sensors.

I don't know how the mileage plays into things since I still running my stock injectors, but it does sound like the above mentioned injector issues.

 

tested glow plugs and got the buzz test done also both test ok from what i can tell the gpcm work like it should to. and filled up with fuel from chevron maybe i had bad fuel
so i changed the fuel filter very dirty and added diesel kleen im gonna run it for a couple of days and see if it goes away.
will keep yall posted

 

Thanks for the update and good luck!!!

 

i ran some good fuel and deisel kleen through about 3 tanks and problem solved

 

Congrats!!!!

 

its started back after a good week of regular driving 15 miles to and from work could i just have dirty fuel system?
ANY IDEAS GUYS???????????

 

Might be time for another filter change. Diesel Kleen will clean the fuel tank out and send it strait to the filter.

 

Did you switch fuel stations, or stop using Diesel Kleen? How old is your engine oil? Do you ever get out and drive it longer than the 15 mile trip?

Make sure the oil is full and fresh, the new filter is clean like Barry suggested, and keep using the DK. Can you get a cylinder contribution test done? You may have a worn injector not spraying the fuel properly.

 

oil is 3000 miles old and i stopped using dk but now it stopped again so im gonna just let it ride for a while until i change my oil and FF
