Narrative:

Mar/tue/04, I was assigned to aircraft, #1 engine for shakedown and routine borescope. At approximately XA30 after letting the engine cool down, I started 'bore.' I saw some damage to the inner combustion wall. At this point I asked inspector to also take a look. We then did a cold side inspection to see if cracks were on that side, none were noted. At this point we contacted our lead inspector, who, in turn, contacted supervisor. Asked to also look due to his many yrs of borescope work. Agreed there was damage that should be watched. Closed motor. Mapped damage on paperwork and turned in to production who then faxed to engineer. On front of paperwork placed note 'engine may need to be put on watch status.' we had checked maintenance manual and believed that it was within limits. Engineer saw report and it said it was out of limits and had another 'bore' done in ZZZ. Engine was changed at that station. Power plant engineer went to office located at other end of hangar and started asking questions about engine. The inspectors involved in this were not there, this at approximately XF30. This aircraft was at gate and departed.
