Probable cause
The partial blockage of the No. 2 cylinder injection line/nozzle by a transient contaminant, which induced an excessively lean mixture in that cylinder, and the subsequent overheating of the cylinder and intake valve. The engine power loss was due to the open intake valve allowing hot exhaust gasses into the induction system. The contamination was due to inadequate installation/inspection procedures used by the operator's maintenance organization when the fuel system was reinstalled on the engine following the overhaul.
