Can you see the ball? Here's how we get "foreign objects" out of kids ears sometimes - clean the surface of the foreign body. We use alcohol or acetone, but brake cleaner would work for you. Make sure and let it dry. Put a drop of gel superglue on the wood end of a cotton tip applicator (a long wood stem q-tip) and gently hold against the ball - hold it still and count to 100 real slow. Gently pull the object out. This is especially exciting on a hyperactive two year old, so you should have no problem doing it on a 7.3
Pulling the cover isn't a desirable method - the engine has to come out of the truck to do this because the oil pan has to come off to get the oil pickup tube off.
