Well back when I bought my truck It was all stock, then I got an exhaust. Out of no where my truck started to put out whitish smoke that smelt like burnt oil, weeks later I tuned it with Vivian's looney.. It still persisted, I returned it to stock and it still did the same thing. I then did my oil cooler and EGR delete and problem went away, then re-tuned the truck and no issues
Fast forward 20k miles problem free and tuned by truck source diesel, I noticed today that same smoke is back when i start driving at 1200 rpms the smoke puffs out then it goes away.
What on earth could this be? I've been told possible injector or injector o-ring issue or turbo seal issue, but I dont think those issues would be this sporadic do you? I also buzz tested my injectors and it passed flying colors. Also monitored all injectors in a contribution test and al were with spec not dipping or going below 0. FICM voltage never below 48v even cold cranking
I just changed my oil to Rotella 5w40 and I always use Rev x fuel additive.
