Cummins ISX Smoking

? my cummins smokes after i have changed a egr valve. and y oil temperature reaches 220 on my 2006 international what could be the problem

 

cummins r always a hot engine 220 i should think is normal the time is hot as hell

 

220 is fine, oil is always hotter than coolant.

 

my 09 cummins isx has started blowing black smoke during regeneration when you shift gears and get back into the throttle during regeneration it puffs black smoke been in the shop 3times in the last month still not fixed.

 

I have a Peterbilt '06 with an ISX 475 hp.In july 09 i had the EGR changed, since then it smokes when shifting when goes up hill (more than normal)OK!.I went for annual inspection and emission test(plated in ont.) i had 34%, max is 30%.I took it to cummins and they changed again the EGR under warranty.After that i had 38%!!! I went back to cummins, they did a clean up with a product, a 5 gal.can for about 50 min. and they adjusted the valves, i paid $750+tx.Now i had 48%!!,and they said oh! we must change the injectors and they did, after that i had 28% wich is very high!This time i paid $5100
What do you think?

 

i think you got took to the cleaners..........

way to much work (and money) to fix a problem correctly

 

i think they just were throwing parts at it..

 

Try a pilot supply website. Sportys Pilots shop has them. Google it then search carbon monoxide on the website and you'll find them.

 

You have been luck I have had same smoke problems and heavey soot it has been in more shops than I can count and in the last 6 weeks its has han an EGR valve EGR cooler Oill cooler Air to Air, and the last week they did the turbo actuatior and shaft today 2200 miles and 1 week later that blow apart and now they are putting on a new turbo and this is all work done by either Cummins or and International dealer this is the worest engine I have ever had. And this is my 6 th truck

 

Remove and clean/replace your EGR differetial PSI tubes, Bottom left hand side of the motor they are 2 small steel lines. They can plug up with soot
