Is that his opinion is it it a company decided fact? Too often people at the dealerships speak without being able to back it up.That all makes sense but the dealership tech told me it was a set of improperly heated cylinders sleeves.

Please challenge it. I am just giving you what I was told. But, we all know how much fake news exists in the world today!Not looking to challenge you but how can that be if it’s always the same cylinder in question? The tsb only refers to engine oilers improperly installed. After reading about this for so long unless he can produce a corporate document stating that fact I don’t believe him.
Incredibly there is very little technical surety on this issue.
Please keep us posted including the date you had your short block installed.So my engine was replaced around ~15k. I now have ~46k on the truck. I swear twice this past week during early morning cold starts that I have heard the engine knock come back now. I'm going to be paying attention to it a little more now.
After I got my long block in my 19. The oil interval is now 7500. Interesting!I still think it was poor metal quality in the cylinder sleeves...#7 cylinder is the last cylinder to receive oil pressure and others have stated scoring on other cylinders..
The most convincing evidence for me is my 17’ and 19’ Titans oil change intervals for severe and normal service were 5000 miles..
On my 20’ Titan the oil change interval for normal service is now 7500 miles....
Yeah... One thing to keep in mind is that there are different schedules for standard vs severe operating conditions. Here's the list of "severe operating conditions" from the 2020 owner's manual:After I got my long block in my 19. The oil interval is now 7500. Interesting!
