Cummins ISX15 crankcase pressure

When you rewire it did you match the wires like you took it off?

 

Could anybody tell me where the crank case filter is on the 2019 ISX 15 I’m getting a high-pressure crank case cODE,the Peterbilt guy give me a new filter for it but it looks like the same as my old 2013, I’m not sure where the filter is on my new one

 

I didnt think the X15 used a crankcase filter anymore like the ISX15 did. The ISX15 came with a empty canister as a filter option as Cummins deamed it useless and said it caused unneeded back pressure. I think the parts guys just assumed you had a ISX, probably because your calling it a ISX..... which it is not.

 

They now have lifetime filters. Google it

 

I have some blow by on cummins isx 15 only from the oil cap when i open it and none from the crankase filter ( hose that goes down below the engine). I think i add 1 gallon every oil change and that is from 12-15k miles. Ever since i know the truck it has blow by not sure if that is normal or notbut just sharing my expirience. Still driving it 7.0mpg
