I have read this entire thread and have a few observations.
Ford has determined some cases of oil passage clogging has caused engine failures. Truthful or not, they have blamed the problem on non OEM filters. This conclusion and report gives them some control over clogged oil passage engine failures regardless of how scientific (vs anecdotal) the research and evidence are.
If filter material is clogging the oil passages, who knows which filter caused it? It could have been from a previous change, or a good filter could have had some media debris in it. Ford must have found a few bad aftermarket filters dumping media and causing failures, so they documented the warning. Do they have evidence and research to back the service bulliten?
The problem might be an engine design problem that allows small amounts of debris to block passages. This quantity of debris may cause no problem in other engines. Certainly a filter that disintegrates and dumps media will leave deposits on the pick up screen.
The key part of the diagnosis is if filter media is actually clogging an oil passage. Filter media on the pick up screen may all that is needed to indicate such.
Your problem is that your truck came in with an aftermarket filter putting you in the "denied" category for a warranty claim.
This reminds me of sludging problems with the 2.7 Chrysler engine, unless you had the dealer do severe service oil changes. you were likely screwed.
Some engines require the dealer do the oil changes, unfortunately you don't know which ones until it is too late.
