What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 7/26 aicraft departed ksgj for keyw, flying south on the airways to melbourne and then southwest to keyw. Approximately 20 NM northeast of 1US an engine vibration was felt; the vibration increased in intensity over the next 60 seconds and checking engine monitor guages showed that EGT for the #1 cylinder on the right engine had risen to the mid 1500S from the mid 1300S. Contacted ATC and it was asked for the two nearest airports, elected to fly TO1US. Reduced power, which alleviated the problem, and landed at 1US without incident. Upon landing it was discovered that there was not a mechanic available nor was there a rental car closer than palm beach. Restarted the aircraft, taxied to a secure area and ran the right engine at full power for 60 seconds without incident. Pilot felt that the issue could have been an injector and that it may have resolved itself, he decided to attempt to complete my flight to keyw and filed an IFR flight plan to do so. Upon reaching approximately 2000 feet, at full power, the engine knock reoccurred. Power was reduced, contacted ATC, cancelled flight plan and proceeded to kapf. By reducing the power the ?knock? Was eliminated and the flight to kapf was without further incident. At kapf, aircraft was taken to Naples air center maintenance where a mechanic determined that the issue was an exhaust valve on the #1 cylinder of the right engine.
