In February 2025 we performed the Wobble Test(Lycoming Mandatory Service Bulletin No. 388C) on our IO540-K1G5 with 1700hrs in service and found all valves to have adequate but not excessive play. Our engine was built in 2003 and has the High Chrome exhaust valve which are supposed to help prevent valve sticking.
In the 300+ hours we've flown since acquiring the airplane in November 2020 we've used Camguard and changed oil at 25hr intervals no longer than 5 months calendar time.
