Narrative:
I replaced #2 engine high pressure valve on oct/fri/03. I was notified of #2 engine problem on oct/tue/03. Conversation with reporter revealed the following information: the reporter stated the right engine high pressure bleed valve was replaced per the airbus 300 maintenance manual and checked ok on engine run. The reporter said the airplane was flown for 3 days and when taxiing out of a gate the right engine overheat warning alerted the crew. The reporter stated the airplane taxied back to the gate where it was found a failed high pressure bleed valve to pneumatic duct clamp weld had failed. The reporter said the clamp was replaced and the trip departed.
