I suppose the valve seals would make sense as to why we see a good amount of oil in our catch cans, or at least I do. The tolerance on the seals may have been deemed necessary for the high rev's of the motor though.Not trying to insult, but a common misconception about failures is that there is a single root cause. From what I can tell, there have been a number of different issues. One is valve seals, for instance. Not really a major issue, but Ford has been kind enough to replace engines for a valve seal issue. The engine isn't "blown", but I think many have been associating oil usage with engine failure.
If the engine was out of warranty, most of us would replace the bad seal rather than the entire engine.
That's just one example - I understand there have been some other failures that were more severe and had different causes.
