kschachn, Finally a non-trolling post. Congrats!
This was back a few years. They said it was ADBV material. They might have had a point, as I said above, about aftermarket oil filters.
I thought there was a more recent set of info on filter material clogging engines.
Here is the warranty-denial stuff:
Engine Damage / Non-Ford Oil Filters - All Model Years, All Vehicles
reference:
https://www.ford-trucks.com/forums/881033-attn-use-motorcraft-oil-filters-only.html
A review of warranty claims indicates that engine damage caused by defective non-Ford oil filters is being claimed under Ford warranty.
The check valves in some non-Ford filters disintegrate causing small rubber debris (frequently red color) to migrate into the engine's oil passages where they restrict flow. This restriction causes components (such as the variable cam timing phaser) to fail, and causes engine knocking / ticking /rattles.
Please reference:
SSM #18921 (Published: 11/03/05)
SSM #19642 (Published: 03/01/07)
TSB #06-19-08
Repair of engine damage caused by defective non-Ford oil filters is not covered per Section 3 of the Warranty & Policy Manual.
Category: Powertrain - Engine
Do: Look for bits of rubber (frequently red color) when repairing damaged engines.
Don't: Submit a warranty claim for damage caused by defective non-Ford oil filters.

The only way disintegrated ADBV material could get into the engine is if the media blew out or the bypass valve opened and let stuff by the media. Otherwise, the bits would be caught in the media as the ADVB is on the inlet side of the filter.
and here they don't mention adbv material explicitly:
