Dear God, i haave had to drive my car and haven't heard anything so I hope to God that it hasn't damaged my engine. I can't see it every time I go under the hood with my magnet to try and pull it out, I dropped it on the belt side of the Vee and it slid under something. Could it have fallen out?

If not, removing the UIM is probably the only way to get to it right?
Thanks for all the help
