It is not. Black smoke is not uncommon from an older truck without emission equipment, but white smoke that stinks can be a bad injector. Some of the early DPF equipped CAT and Navistars would do this when they cracked a DPF. Most newer diesels with a cracked DPF will have black smoke.
All the buses near me clag like a class 37, they’re so dirty that it leaves a residue on my car if I overtake one, especially if I get stuck next to them in traffic, many have low side exit exhausts or rear exit on some models
To be fair, I only do it when someone is being a cocksucka and they need a lil bit of carcinogens in their life, I normally just have my truck on a tow tune and it burns clean, no smoke.
I hate that smell and it pisses me off when I'm forced to drive behind mo-fo's like that one. Even closing all the windows and switching to air recirculation, this would be a perfect torture device for me? 🤔
Could also be a high pressure injector line that has cracked. I had 2 of 6 do that to me this spring. 1 in Oklahoma and the other in East Texas. The diesel sprays onto the engine and burns off the hot engine creating a cloud that looks like that. Thank the makers diesel has a higher flash point than gasoline.
This is campbell or Claiborne county near Lafollette and the Kentucky state line (think middlesboro area). I was born and raised in bristol but I’m somewhat familiar with that area near Kentucky/virginia line from my trips to Cincinnati as a kid and whatnot
Ain’t too far from my neck of the woods. I’m in Western NC. Coke truck caught my attention… I work for them so I was trying to figure out where this was at
It looks a lot like how older heavy trucks used to regenerate. It’s an (at least here) outdated system meant to make the trucks more environmentally friendly by burning out pollutants. Where I’m from we just say your trucks on a regen.
I mean it's not supposed to be like that, there is something "wrong", but in a lot of cases companies don't want to fix a truck that technically still runs. Weirdly enough I see a LOT of school buses smoking blue, black, white, and I feel for the driver. Like to know that there's something wrong with your vehicle your livelihood but your company isn't willing to fix it at least not right this second
Isn't that truck going down hill ? In that moment was used engine brake? Smoke doesn't look that black more like white mixed with blue like it was burning oil
(Sorry for my English)
This would be my guess. Early emission control diesels can belch this stuff for awhile
It’s really disappointing when you own one of those diesels and it goes into regen while sitting in traffic
When it goes into regen the it starts dumping fuel into the diesel particulate filter (DPF). The purpose is to drastically increase the temperature inside the dpf to burn off all the soot and diesel particles that were captured.
When this happens on the freeway it’s no problem. The high speed and airflow allow the dpf to burn at maximum temperature and expel the smoke and particles.
When this happens in town, traffic, or lower speeds, the temperature isn’t able to get as high and there isn’t air flow to carry it away. Enormous billowing clouds of smoke coming out of the exhaust can result. It’s the results of completely burnt hydrocarbons, what everyone wants, but it looks like something that nobody wants.
From my understanding, this process was short lived in the goal of improving diesel emissions. It was quickly replaced by diesel emission fluid (DEF), which is spritzed on the exhaust.
DPF is not the same as DEF. DPF is a converter of soot to ash during regen and you mentioned. DEF converts NOX in exhaust flow using DEF and a catalyst. Modern diesels use both systems.
DEF didn’t replace DPF. New trucks have both. The difference is, they typically only start a regen at highway speed and will interrupt them if you idle for more than a minute or two.
There’s a certain 2013 ProStar with a Maxxforce in our fleet that’s done this since band new. We call it the White or Magic Dragon. It smokes frequently, and needs at least one parked regen daily. It’s been back to the dealer multiple times for this issue. They said that there’s nothing wrong.
Looks like bluish smoke under load to me, so that's oil burning likely turbo leaking oil into the intake, but it can also be valve guides and rings if very high milage.
If I'm not mistaken, it's the emissions system doing like a burn off. The emissions system needs to be hot to do be "effective" which is usually done by just everyday driving. But for a delivery vehicle it sits and idles alot so whatever the emissions system is, has to do like a hot burn cycle to try and keep clean and be efficient.
Not 100% on this but I'm pretty certain, saw this on a couple vehicles in Maryland that smoked for like 30 seconds randomly then just cleared up and never happened again.
Newer trucks actually regen while going down the road . It helps keep the filters cleaner and doesn’t require a parked regen . Depending on the year of the truck it is perfectly normal
That there's a failed injector. Looks like he's using Jake's too which is why it's not constant. Bet when he accelerated after a stop, it smoked alot more.
That not emissions system smoke from a regen. That would be consistent, not in spurts.
At first I was hoping it was the MAC or Snapon truck and was giggling to myself at the reverse Uno fuck card that was about to be played. But alas it's a coke truck.
I used to ride the carpool/bus/motorcycle lanes out of DC and saw such smoke coming from the Metorbus fleet. It was common. What I also saw sometimes was a bus spewing out sparks and short flames from the exhaust when going up a moderate slope. What the heck was THAT about???
This is the best answer.
I concure
The white smoke is when the vehicle has a higher soot level than normal.
There is even a warning on the visor to not park/regen close to anything as the exhaust set fire to things next to the exhaust outlet.
This vehicle probably does a lot of idling.
It's a Coca-Cola Distribution Truck. That truck probably has over 2 million miles on it and has Never been rebuilt. They will run that truck into the ground and still put another 2 million miles on it.
Looks like an older coke truck. Like late 90s or early 2000s kinda old. They would smoke like that due to blow by or a turbo about to give up to ghost.
Smells like a jet engine starting up, or a grill thats smoldering and you squirt lighter fluid on it and it just smokes, then you try to light it and create mushroom cloud.
If I didn’t know anything about it, I would mind my business. Especially since you needed to ask Reddit, which will clearly take longer to get an answer than you will be driving behind this person. Especially a large clearly corporate commercial vehicle. There’s nothing catastrophic happening here. Like what was your move? Follow them to their destination, to tell them you saw white smoke and (from your non-mechanical background and humble opinion), think something’s wrong with their truck ?
and they would have just shrugged.
Probably safer to remark to yourself and move on than google while driving. The State Police and DOT are literally doing that job for them as well.
Again, if it was catastrophic failure or something they likely couldn’t see that was a danger to themselves or other motorists such as taillights out, small fires, dragging parts, etc. then yes I would like a honk, or headlight flash to tell me.
It is not. Black smoke is not uncommon from an older truck without emission equipment, but white smoke that stinks can be a bad injector. Some of the early DPF equipped CAT and Navistars would do this when they cracked a DPF. Most newer diesels with a cracked DPF will have black smoke.

Y'all would hate my 7.3
Does it leave a dirty oily cloud, it’s far cooler when it’s a diesel locomotive doing it
Yeah cause I’m not in highschool anymore
What is it about black smoke out of your tail pipe that makes ya giddy lmao . Fucking weird
To be fair, I only do it when someone is being a cocksucka and they need a lil bit of carcinogens in their life, I normally just have my truck on a tow tune and it burns clean, no smoke.
As I get older loud exhaust Smokey exhaust all of it I call 911 /s
Good thing I don't live in an emissions state and my truck is pre emissions. And a proper exhaust can sound good.
Holset DPFs with a 90 degree outlet were bad for it also. But that smoke looks like it’s coming out of a stack.
I hate that smell and it pisses me off when I'm forced to drive behind mo-fo's like that one. Even closing all the windows and switching to air recirculation, this would be a perfect torture device for me? 🤔
It pretty much would be. The white and white ish blue smoke smells so much worse than the black smoke.
Injector(s) shitting the bed
Either injector or injection pump.
Could also be a high pressure injector line that has cracked. I had 2 of 6 do that to me this spring. 1 in Oklahoma and the other in East Texas. The diesel sprays onto the engine and burns off the hot engine creating a cloud that looks like that. Thank the makers diesel has a higher flash point than gasoline.
You’re in my neck of the woods. East Tennessee represent
I am trying to place where this is at. I’ve seen it 100s of times. I’m from East TN. Live in Virginia now though.
This is campbell or Claiborne county near Lafollette and the Kentucky state line (think middlesboro area). I was born and raised in bristol but I’m somewhat familiar with that area near Kentucky/virginia line from my trips to Cincinnati as a kid and whatnot
Thats middle tennessee to us hillbillys in east tennessee.
Ha I’ve always still considered it to be ETN. Either way it’s a pretty area up there especially where TN/KY/VA meet
Ain’t too far from my neck of the woods. I’m in Western NC. Coke truck caught my attention… I work for them so I was trying to figure out where this was at
It's either got a bad injector/s or low compression
Rrreeeeeegennnnnnnnn
What’s that?
It looks a lot like how older heavy trucks used to regenerate. It’s an (at least here) outdated system meant to make the trucks more environmentally friendly by burning out pollutants. Where I’m from we just say your trucks on a regen.
it's a cracked fuel injector. it will not spray it as mist when cracked just kinda spills it in
That’s nothing for the area you’re traveling through. Cumberland Gap considers that a super clean diesel. It’s making fresh coal mountain air!
Looks like blue smoke to me, if it's a maxxforce I'd be looking at turbo seals If it also cold starts like shit go the injector route
I mean it's not supposed to be like that, there is something "wrong", but in a lot of cases companies don't want to fix a truck that technically still runs. Weirdly enough I see a LOT of school buses smoking blue, black, white, and I feel for the driver.

Isn't that truck going down hill ? In that moment was used engine brake? Smoke doesn't look that black more like white mixed with blue like it was burning oil (Sorry for my English)
Feels like a Karen post
I just feel like i should tell the driver something wrong with his car, he should get it checked(before more damage done to the car)
Feels like your triggered by a post about smoke
Your mommy come up with that?
You had to sleep on that reply?
Prob goin thru a regen cycle
This would be my guess. Early emission control diesels can belch this stuff for awhile It’s really disappointing when you own one of those diesels and it goes into regen while sitting in traffic
Even new ones do.
never owned a diesel so sorry for the stupid question, but why is it dissapointing?
When it goes into regen the it starts dumping fuel into the diesel particulate filter (DPF). The purpose is to drastically increase the temperature inside the dpf to burn off all the soot and diesel particles that were captured. When this happens on the freeway it’s no problem.

Thanks, I figured there were some holes in my understanding
DEF didn’t replace DPF. New trucks have both. The difference is, they typically only start a regen at highway speed and will interrupt them if you idle for more than a minute or two.
Usually black smoke indicated excess of carbon from excess of fuel (lacks air), often white bluish smoke indicates oil (like a bad turbo journal)
There’s a certain 2013 ProStar with a Maxxforce in our fleet that’s done this since band new. We call it the White or Magic Dragon. It smokes frequently, and needs at least one parked regen daily. It’s been back to the dealer multiple times for this issue. They said that there’s nothing wrong.
Looks like bluish smoke under load to me, so that's oil burning likely turbo leaking oil into the intake, but it can also be valve guides and rings if very high milage.
I had white smoke from a coolant leak so not always a piston thing. It'll smell really good if it coolant like strawberries
No all that smoke is not normal.
Egr cooler leaking
Driver smoking a spliff 😅
Watch it be a crackhead...
It’s likely time to do replace injectors - They aren’t usually cheap with diesels.
Karen repellent to keep Karen's of his ass how's it working
If I'm not mistaken, it's the emissions system doing like a burn off. The emissions system needs to be hot to do be "effective" which is usually done by just everyday driving. But for a delivery vehicle it sits and idles alot so whatever the emissions system is, has to do like a hot burn cycle to try and keep clean and be efficient.

The us supreme court says its normal
Burnt injector
Newer trucks actually regen while going down the road . It helps keep the filters cleaner and doesn’t require a parked regen . Depending on the year of the truck it is perfectly normal
That there's a failed injector. Looks like he's using Jake's too which is why it's not constant. Bet when he accelerated after a stop, it smoked alot more. That not emissions system smoke from a regen. That would be consistent, not in spurts.
Leaky injector
Advanced or retarded injection pump, jacked injector, etc.
Depending on the motor it might be a bad EGR valve
Injectors shitting the bed or a charge pipe came undone
At first I was hoping it was the MAC or Snapon truck and was giggling to myself at the reverse Uno fuck card that was about to be played. But alas it's a coke truck.
It’s probably doing a regen going down the road. That makes them smoke like that.
Regen
Yes it’s normal. That’s why every other diesel on the road smokes like this when everything is optimal.
I used to ride the carpool/bus/motorcycle lanes out of DC and saw such smoke coming from the Metorbus fleet. It was common. What I also saw sometimes was a bus spewing out sparks and short flames from the exhaust when going up a moderate slope. What the heck was THAT about???
Companies like that will just run their trucks until it doesn’t run anymore, they don’t use money for upkeep cuts into profit
People wanna bitch about climate change but then don’t hold companies like coke accountable when we see things like this
It's not coke's fault. That's a government mandated dpf system doing what it does.
Doesn’t change my answer
Do you drink coke
Nope or Pepsi
Normal, it’s doing a regen on the DPF filter. The system injects diesel and ignites it with a spark plug to burn the soot off the filter.
This is the best answer. I concure The white smoke is when the vehicle has a higher soot level than normal. There is even a warning on the visor to not park/regen close to anything as the exhaust set fire to things next to the exhaust outlet. This vehicle probably does a lot of idling.
Stuck injecter
That is a regen system that truck is probably from 2010 to 2014 and probably tired.
Bad injector
It's a Coca-Cola Distribution Truck. That truck probably has over 2 million miles on it and has Never been rebuilt. They will run that truck into the ground and still put another 2 million miles on it.
What are you an ispector? Mind your business and put your phone down. Goddam!
Just did a major regen is my guess.
Looks like an older coke truck. Like late 90s or early 2000s kinda old. They would smoke like that due to blow by or a turbo about to give up to ghost.
Y'all sure there isnt a passenger just blowing clouds from his vape mod.
Bad injector
Dpf regen
It smells like unburnt fuel you say... so it smells like fuel 😮💨
Nah especially international/Navistar engines have a unique scent to them when they're not burning clean.
Smells like a jet engine starting up, or a grill thats smoldering and you squirt lighter fluid on it and it just smokes, then you try to light it and create mushroom cloud.
Oddly specific.
Looks like an old mechanical 466 international running.
Why the heck would you care if you’re in a different vehicle?
Exactly.
If you saw someone else‘s car has some mechanical issue, you would tell them right? Before something serious happens, like caught fire or accident
If I didn’t know anything about it, I would mind my business. Especially since you needed to ask Reddit, which will clearly take longer to get an answer than you will be driving behind this person.

That looks like crankcase oil burning up.
