What causes constant crankcase pressure code?
I have a 2008 450 isx cummins with 612000 miles. I keep getting engine fault code for crankcase pressure. when i change the filter it doesnt have much oil on it but the code will go away for about two days then it comes back when i have a load. after about a month i will get the red engine light to shut down if im climbing a hill with a load. so i change the filter and go through it all over again. i've changed the sensor already but that didnt help. i remember the very first time i had a crancase pressure code i changed the filter and it was dripping wet with oil. it was ok for about a year after that. when i change the filter now its not like that, its almost dry compared to the first time. i thought maybe i need rings but im not getting any blue smoke. and if i did need rings wouldn't the filter be wet from excessive oil? i dont know what else to try and the few mechanics i talked to shrugged thier shoulders.
Is this a good question?
