No Codes! No Lights!

Many thanks! About 700k on the DOC. At the dealer I remember all of the above being discussed….I think? These guys are known to be the best in my area…for a Cummins anyway. Ok, it’s been three days and about 1600 miles with my new DPF and zero regens, no halfway, nothing! Fixed? Maybe. However, for the last two days I’ve been watching the MP gauge more than the road. After a coast then to full load it goes to the mid 30s then fades to 27 or so. Also getting more MP from the engine brake sometimes than I can with the gas pedal. Did a soap test at just a high idle and getting some foam from the CAC. Now…parked close to Peterbilt. Tomorrow… gonna install a new CAC if they have one. Thoughts?

Thank You!

 

Did the CAC decay test. Pressured it to 35 psi and lost less than 10 psi in 5 minutes. 15 minutes later still had 20. According to a famous ISX YouTuber, that’s plenty good. Fourth day since new DPF and no regens yet! Yippeee!
Gonna just keep running it and see what happens. Thanks for all the help!!!!!
