The Bore Scope I bought to find a bolt dropped into the intake on my '48 Suburban 350 V8, will fit into a plug hole. It has a bright LED light and a mirror attachment. It also has a magnet to retrieve wayward objects. I think it was $29 shipped. Saved my bacon and well worth the $. There was a warning included in the box, "Not for use as a Medical Device". Why would they put that in there? My guess is someone did it with not so good results.
