6.7 Cummins smoking on hard acceleration

[brianm]

Greetings friends, So I noticed my truck (2012 ram 3500) is starting to throw a bit of black smoke under hard acceleration. Nothing crazy but the thing is it never did anything before it was just clean mabey a puff right at the start for a second now it lasts for probably 5 or so seconds before it goes clean. Is this something I should be concerned about? Air filter is new and the truck is deleted. Thanks

Has your boost dropped at all

air filter maybe restricting ?
maybe time for a new one?

Do you use fuel conditioner? I personally have noticed diesel fuel quality seems to be going down hill lately. Filled my wifes diesel the other day and it was stinking and smoking something terrible. Thought I was in trouble...Burnt half tank ran like ch!t, topped up with premium diesel and ran like a top again. Also added conditioner. Summit Ric recommended to use Alliant Diesel Lubrigard. Tried it and I think it works. In my 2022 f350 I can watch DPF ash load and it climbs much less slowly when I use conditioner. Can get at GCL in Edmonton.

I have been using random stations lately…. WHO ever is cheapest. Air filter is clean but I don’t have a boots gauge to know if the boost dropped or not maybe I can check it with my scan tool live data .

when was the last time you changed it though ? 50,000 kms ago ?
Maybe an injector is sticking open and the fuel additive can help too. Perhaps too much fuel is being burnt

Air filter? About 6500 km ago but it was last year now when I look back at my maintenance book . it’s a wix paper job . Yeah maybe I could run some cleaner through it but I rarely drive it which might be the problem to .

Start with a new filter. Black is unburnt fuel so either its not getting air or its getting too much fuel and a new air filter is the cheapest option. Check under the hood for soot. Maybe you have a boost leak

[brianm]

Yeah I’ll give an air filter a try I guess and have a look around this weekend for soot . It’s nothing like the video lol .

No hood stack, 11", 24s and 38s, compound turbos.....I dont think my truck is useless

 

[brianm]

Depends on what your using it for . For me it would be useless. I use it for pulling my trailer and dump runs so yeah it would be useless to me . Reliably is most important to me in my situation

nothing tows better than 1000hp to the wheels let me tell ya haha.
Reliability isn't an issue after re building what an un named shop did to it in BC
Been to all the shops, as the saying goes want something done do it oneself.

My daily is a 96 12 valve haha. rides like ass compared to the mega.
Only shop I would recommend is inline automotive in south edmonton. If you cant get your issues figured I would take it there. Denise has been more than helpful/fair to me

I like to hit speed bumps at full throttle and going fast.

It would be useful for me

The best place I would recommend is in Summerland, Deputy Diesel. MArk Sheriff is a very good man
