Hello everyone, I've got a cummins NTC 350 with a CPL of 021 In a peterbilt 359. Lately it's been pouring out blue smoke at startup, idle, and at normal operating temp. I replaced the injectors and it still smokes know matter the temp or the amount of load on the motor. I recently ran the overhead on it using the inner base circle method within change in amount of smoke it pours out. This cummins has over 800k miles and I've never opened it up to check rings or anything like that. We bought it for a farm truck and it hasnt always smoked this way. Any information would be greatly appreciated. Thank you.
