Picture of Injector Leaking Exhaust Smoke?

Hey guys, think I have injector(s) leaking fuel. I have the really rough/hard starting with the smoke in the picture and REALLY rough idle till the engine gets up to about 70*F ish.

Here's a pic of the exhaust smoke that I want to verify and figure others can use it for comparison as well.

any toys on engine?

mileage/hours on injectors?

fuel filtration system?

get a lab oil analysis ran.

oil level increasing?

run an oil stain test on white paper

how long have the symptoms been occurring?

try a double dose of PS Diesel Kleen in the fuel.

this is NOT a problem to waste time on, do all immediately. engine deaths in these are common from leaking injector nozzles and EXPENSIVE

If it's cold outside, it will smoke like that for a little bit until the engine warms up a little. Mine was doing it and I just had all 6 injectors replaced under warranty earlier this week and it still does it. It only does it for the first 15-20 seconds and stops, which is condensation just like any other car does in the cold. We just warm up quicker, so it doesn't do it as long. I would still do what steelhead01 said in his post anyways to be safe. I just sent my oil out to be tested.

i have never had white smoke out of the tail pipe due to cold weather.

only time i ever got anything white coming out was when it was 0* and even then nothing at idle only a mist when i pulled away that dissapated within a second

i dont wana tell u to go throw parts at it but seems rough idle and white smoke together at first start is a pretty sure sign u need injectors

pull your dipstick and whipe the oil on a towel let it hang upright for about 15 min if there is a yellowish halo around the top you got an injector problem my 06 blows some when i first start it on cold days but thats just a little cold fuel in the combustion chamber sounds to me like you got a bad injector or a couple bad ones that are hanging open. Make sure you are changing your fuel filters

MY FCA valve hanging did that to me, guess my rail pressure was all over the place. I though it might of been an injector myself. I took it off, and beat it silly with a rubber mallet until the piston inside was bouncing freely, and i guess it fixed it, been 3 weeks now. I would of bought a new valve, but I don't want to start throwing money at it just guessing, if i don't have to ,and the dealer couldn't figure it out either. Definitely check the oil , don't want a melt a slug.

At about 35*F I will start to get white smoke untill it warms. Never had a problem otherwise. I put an injector cleaner in about once yr for 2 or 3 fuel ups, or if Im on a long haul I will use one at ever fill. Hopefully its nothing, good luck.

it was probly about 40*F out when I took the pic and the truck had been sitting for a couple days.

I have 97K on it,
stock fuel filtration (I know, I know, I shoulda put the 2 micron filter I have n the garage on it),
Bully Dog PMt that never goes above Tow,
exhaust and everything else about the engine is all stock

I just got back from a weekend out of town, will try and check the oil level in a day or so (It's not my daily driver)

I'm not sure when the symptoms first showed up... it sits sometimes for a week or more at a time....

Bad fuel did it for me. Wiegel's and diesel shouldn't be used in the same sentence. I was having hard starts and whiteish smoke when cold.

Added a heavy dose of dieselkleen to get me through the tank, filled at my regular Exxon and replaced the fuel filter and the truck has never been happier.

i think 97K on stock filtration would def point towards injectors. do u ever add any lubrication during fill ups? if so what kind

Power Service Deisel and sometimes Howes, but not much in the summer, that's mostly for winter...

So, what would be a good cleaner to run through if my oil level isn't up or contaminated with fuel?
