Well....
1500 flight hours on my 2004 DA40 Legacy.
I'm in annual and Cylinder 4 had lousy compression (upper 40's after many tries). They tried the in place valve lapping but it won't seal. Seems to be a warped intake valve (also noted it had lots of deposits. This Cylinder has always tested a bit lower than the others:
2018 66
2019 64
2020 64
2021 70
2022 71
Taking it off now and shipping out to a shop for repair (hope for about a 3 week turnaround or less). I ordered a new Lycoming Cylinder through AirPower just to have a spare - wait time about a year. No Superior Millenium available either. Supply chain really has done a number on many of us.
Looking for any thoughts on locating a used, serviceable cylinder (yellow tagged) or new or overhauled that I am not thinking of. Shop has had some planes grounded for up to a year when they needed a new engine.

Re: AOG - Warped Intake Valve
Reach out to James Watson at Watson Aero. james at watsonaero.com. He did my overhaul and I'm not sure what he did with my four old cylinders but I don't have them. He may have others as well. Or at least a lead on where to get some. He was able to get Milleniums for me at the height of the supply chain issues.
