While automotive industry applications for the ViewTech video borescope are nearly unlimited, in the following case study, the borescope was used to save an auto repair technician after a mishap that could happen to anyone. After this tech used a breaker bar to remove a spark plug on a Chrysler 3.8 L V6 engine, examination of the plug revealed that its ceramic body had been cracked and tiny pieces were missing. While some of the pieces were found on the cylinder head plug seat, only a visual inspection of the combustion chamber could determine whether any shards had fallen in through the spark plug hole.
