okay here is the skinny on this guy.  The 6 hour timer is BS.  Unless he spawns 3 miles away and has multiple pat paths.  I think the timer is much longer.  I was there on a Monday at 11pm server on silvermoon got a target on him using a macro. (/target time). unfortunately I didn't see it before it flew off too far and I lost the target. but what I did find later was a dead time lost proto-drake at about 11:15.  The exact coords for the dead proto was 28.08-51.8. in a little valley north of valkyrion.  so too bad I missed that one. I figured that I would just hang out the next day and get it.  Tuesday I waited to log on not by choice but because of maintenance. so at 11am server I logged on. and I flew what I think is the most viable path that it follows based on the info I've found. he comes from the south of the engine of the makers through the blue drakes over and to the north of the frigid tomb(left turn ) past and to the north of the brood mothers nest into bor's breath ravine (right turn north) toward the valkyrion village and onto the snow drift plains. from there its anyone's guess but that's the only hunk O path I have any personal EXP with.  as for the timer I was there on Tuesday from 11 am to 1am on Wednesday morning. that's 14 hours so even if 1 person got it before me I would have seen its corps because its not sinkable or I would have caught the next one. If the 6 hour thing was right.  so okay lets ask a a GM if there is a problem with it. Nope functioning correctly they assure me. 
The macro is as follows
/target time
/target vyragosa
/target dirkee
/stopmacro [noexists]
/tell YOURNAMEHERE >%t<
