Isn't it interesting what you can find in a car's engine compartment sometimes?
When I had my MGB, there was this rattle from the front whenever I would go over a bump. It was really annoying.
My mechanic looked at it, checked the whole suspension and could not find anything rattling or loose.
After he drove it and heard it, he took a magnet on an extended rod, fed it into the fender, and out came a wrench.
luckily my car's engine compartment doesn't have any left over stuff in it.
