I do not know how much involvement Navistar did or didn't have with FOE. But I can say that the agreement between Peugeot and Ford is often misunderstood actually being an agreement based more on the sharing of independently designed diesel engines rather than co-development of the same. The 2.7L TDi V6 and 4.4L TDi V8 were in fact designed almost entirely by Ford while other, smaller diesel engines used by both Ford and PSA under this agreement were designed almost entirely by PSA.

As for Navistar having developed any or all of the upcoming 4.4L V8, the answer there would be no. Even in their own claim they only cite an 11 million dollar development budget which likely wouldn't even be enough to cover the development of a nice set of injectors.

This latest problem goes back to their agreement with Ford to supply small diesel engines, initially with the disaster that became the 4.5L V6 and later with an agreement for Navistar to build the new 4.4L Lion V8 for the Amercan market.....a deal which is falling through for obvious reasons. The 11 million dollar claim cited in their lawsuit likely has to do with money devoted to that effort.
