UPDATE: Thanks to all for help and comments. Two events have shed light on the problem. One my UOA came back from Blackstone and wear metals were down but still high and fuel dilution still a problem. In the meantime the check engine light has illuminated and the truck has an injector problem and a TCM problem. It is being worked on by Ford under warranty. When I get it back I will short change the oil and see what happens. I think the injector issue was the culprit all along but just took awhile to get bad enough to trigger a code.
