Hi everyone, I have a Caterpillar 320DL with a common rail C6.4 engine, serial number KGF01544. Although it starts well, there's a lot of white smoke coming out when it's idling. An ET technician checked it and diagnosed a bad pump, so I replaced it with an original one from CAT. However, the smoke persisted. He then suggested changing the nozzles, so I replaced all of them with new ones from Bosch. However, when installing the nozzles, the CD was not run; the ET technician said it wasn't needed. Additionally, one of the sensors on the pump does not read well. Now, the smoke has turned slightly greyish, but it's still present. Does anyone have any ideas on what the problem could be? Thanks in advance for your help!
