get a magnet on a stick tool (telescoping magnet for those of us that get raped by our friendly snap on man...) if all else fails pop the lower pan and poke around with the magnet that way... i cant tell you how many times my maggy saved my booty with those lil bastards.
i have dropped em more than once... i've even used that magnet to pull timing chains up when i accidentally drop em into the front cover
