2016 2.7l TSB
 

O.K. so I have read all the posts re. 2.7l engine failures with the low oil/smoking engine problem listed in TSB 17-0007. And with page after page of detailed descriptions of how owners went through the painful process of replacing their engines (or replacing the entire truck!) I have YET to see where anyone was told the actual cause of the failure.

Have I missed something, or is this a very well kept secret? Seems to be a lot of very knowledgeable people in this forum who really dig for answers and nobody seems to know why these engines are failing. Anyone know why?

Nope, it hasn't popped up yet
