Need some help on an oops... 
My son changed out the turbo on his 5. 9l, accidentally crimped the 04. 5 flexible turbo oil return line, so went to the dealer to get a new line. They sold him the older, multi-section return line. While seating the return tube in the block, the very end section (with o-ring) of the return line separated and went into the block/oil pan. We drained the oil, used magnets to try to locate the piece, fished around with a thin wire, etc. Can't locate the little sucker. Is the only option to drop the oil pan, remove the piece, and reassemble?
