I just kind of slid it back into place; it definitely didn't take a mallet or anything like the other guy here mentioned. It didn't seem broken to me though. It is possible that I may have somehow loosened it in the past and it only fell out recently, but I just don't see how that would have happened since I've never had a reason to work near that. I will say my Focus was one of the very early ones (second week of production) so it could be an early mistake of some sort. Related; the dipstick shot out of the engine on its own less than a week after I took ownership of the car, spraying oil everywhere. Apparently my dipstick tube was either missing or defective.
