Narrative:

Loss of oil quantity left engine, followed by decreasing oil pressure. Engine shut down, emergency declared and landing geg without incident. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a B757-200 with P&west 2000 engines. He said the aircraft was at FL410 when the left engine low pressure warning light flickered a few times then went out. He looked over at the left oil quantity indicator and it indicated zero oil quantity. He stated the engine was pulled back to idle and the pressure began to drop and the engine was shut down. He said on the ground no visible indications were present of engine oil leakage and the tailpipe was clean. He stated 18 quarts of oil were added and the engine ran and no loss of oil was observed. He related this engine had just had a 5TH stage carbon seal installed. He said the aircraft was maintenance ferried to a maintenance station and the engine was replaced.
