I've been wondering if there existed an automotive version of the
colonoscopy scope instrument. ;-) I could see some usefulness in it,
such as inspecting the inside of the cylinder chambers through the spark
plug hole, or even the inside of the fuel tank, though that could be
dangerous due to the chance of explosion from a spark. Do mechanics use
such scopes at all?
Yes, they can even be had from Harbor Freight:
But better ones are available...
Before digital camera's, Borescopes (often called Boroscopes) were the
But they were big, cost megabucks and delicate... and got more use doing
things like inspections of airline/military gas turbine 'hot sections'
and/or similar industrial work.
Far as automotive shops go, don't know how wide spread their use is.
Probably limited at best.
For looking in fuel tanks... there wouldn't be much to see in there
anyway. A bad fuel pump looks just like a good one, plus illuminating &
navigating around in such a large space would be a challenge.
These things still mostly see use on equipment designed for their use...
like heavy industrial & aerospace applications.
However, for years now plumbers have been using a variation of them for
sewer line inspections.
Have heard the law enforcement industry (and related little cloak/dagger
outfits) now have & use a variety of similar specialized camera's.
