The only external oil line on the '07 WR is the pressure balance line that runs from the oil reservoir in front of the engine to the right side crankcase cover. It normally carries no oil at all, but some would leak if the hose were to become disengaged at the crankcase cover. Even so, you'd have to ride it quite a ways without that hose connected before you lost all your oil. Seems like you would have seen smoke, or smelled something before it was a problem.
Since '06, I've had 3 YZ450's that I owned with this same set up, not one of which ever came loose in all that time. There were two oil lines on the earlier models which were an active part of the lube system. They never gave me any trouble either. External oil plumbing has been a part of motorcycling for most of 120 years without it being "cross-eyed" or a bad design.
On what basis have you decided that the "engine is wasted"? How much oil was left in the bike at the end of this adventure?

Now you think you know what I think.
That's exactly the line I was talking about. Have a leak down test done for informational purposes and open it up.
