Combined Borescope And Flushing Wand
Proposed combination borescope/flushing wand lets operator locate contaminant particles in narrow, intricate internal passages and simultaneously remove them. Video monitor displays view of contamination in internal passage, while being flushed away. Operator sees immediately whether contamination removed. Plastic isolator protects borescope. For further protection and for reduction of blurring, borescope slightly recessed from tip of wand.
