Just an update.... Ford replaced my blown engine with a rebuilt one and provided a 24 month/24000 mile warranty. I was disappointed that it wasn't a brand new engine but the dealership claims that Ford will supply a new engine only within the first 12 months. After that, they will use a rebuilt engine. Interestingly, they will provide only a 12 month/12000 mile warranty on a brand new engine.
Anyway, the 'tour is back on the road and it runs fine with the new engine. Think it's time to look into that extended warranty program....
Thanks to all who posted.
