I have 22,500 miles on this 2017 Ford f150 3. 5 ecoboost. It has started throwing a code of po4db crankcase disconnect. I have been researching and there are a lot of Ford products having the same issue. This code make engine light come on and stay on. It appears it's in the computer system, is my understanding. Sitting still, driving it doesn't matter engine light stays on.
Upon cold start vehicle blows blueish/white smoke for approximately 6-8 seconds then stops. Does not smoke while driving and vehicle runs just fine otherwise. Took to dealership and they said it was a pcv valve stuck open and they relaced it. . . . . That didn't fix the problem.
