The valve guide inspection was due and the owner wanted it done since it was in the shop. The problem has not reoccurred even after swapping the EGT probes. Go figure.
Excellent explanation. I was a flight engineer for 30 years, built several car engines and jet engine mechanic. Your video was a huge help in my learning of GA engines. We have a Mooney w Lycoming 180 hp and "something" in the engine is causing a skip at low RPM. 1-2-3-4 skip, 1-2-3-4 skip. Bad plug, leads, mags (think not), intake leak, exhaust valve, (I hope not) carburetor?
we are checking to make sure the valves have clearance in the guide to prevent seizing. it is very common in lycoming engines. its recommended to check every 400 hours
Looks like an O-360 mounted in the front of a Mooney M20C…? Dog house, cooling air line, and battery case… Where a stuck exhaust valve can cause quite a vibration, while missing 25% of its power output…. Kerry McIntyre? (Mooney Mechanic Extraordinaire, KNR) 😃 - a -
Nice video. We all become better when knowledge is shared! Thanks for taking the time.
Perfect explanation, thanks!
Well done video - thanks for making it!
Great video!!! Thanks so much.
excellent tutorial thanks Sir. best wishes NZ
Nice video! I appreciate you passing on the knowledge/0
Would it make more sense to check the EGT sensor before disassembling the valve spring?

Nicely explained!
Good video, thank you for sharing your tricks with great explanations
Could you post a photo of the two adapter tools you made? I couldn’t see the angle valve one. It was off camera.
I am going to do a video of me using the angle valve tools soon. I'll make sure they are more visible

very interesting and pretty easy, thanks for sharing.
Wouldn't the leakdown test have said the valves were seated?

What kinda airplane? ---- Mooney?
1970 mooney m20c. I used to own it. I still a 1967 m20c maual gear. I flew it here a couple of years ago. Needs lots of work.
Start with the simple answers first .. time = money !
