Cummins ISX CM871 Technical discussion

You are right not all engines have them I think it catches your crankcase vent....

 

I keep mine under 1500 usually 14-15 hundred rpm Cummins will tell you any time your over 1500 you start sucking a lot of fuel..

 

What kind of fuel mpg do you get

 

took out crankcase filter full of black oil , and i'm doing EGR Tune up as Razee suggested,,one of my freind did that and increased fuel milage plus engine runs smooth afterwards. All these sensors and carb buildup needs to be cleaned every 150k miles atleast.

 

6-7 winter Tri weight 100-102 thousand lbs.

 

rawze I was wondering if there would be any way I could pick your brain a lil? I have a few questions. i am new here so I can't pm until i have posted 7 times. Thanks

 

if anybody that's familiar with the calterm software would give me a call I would much appreciate it my names pj

 

Sounds like you may have solved my problem. I am sure I can do this work myself, but have been unable to find a diagram of my 2006 ISX to locate the sensors and tubes. Any suggestions...thank you...sunseeker269
