gasket fell down in lowing timing case

[geetarspaz]

so i was changing my timing chain case gaskets and one of them slipped and fell down in there. i've removed the top half and still can't see where it is and tried fishing it out. i know this is probably a stupid question but should i positively get it out? i was able to see it before but while trying to fish it out it only dropped further down there. it may be stuck or something somewhere or at the very bottom and really am not wanting to taking the whole bottom cover , especially with the vibration dampener removal which i would have to take the whole front end off for that. would leaving it potentially down in there be a foolish idea?

the part that fell is #16 on the right.
