Drew Swenson Posted May 14, 2009 Share Posted May 14, 2009 You don't neccessarily need to OH the engine due to a cracked cylinder---you could just replace the cylinder. For me, the big consideration would be how bad are the cam lobes. If the lobes are pitted or shot, you will need to crack the case open to replace----and then you might as well OH. The other consideration is if you have a lot of time on the engine----or it was sitting around for a long time. Back to the cracked cylinder---why did it crack? Was it getting too hot? I will bet that you don't have CHTs on on cylinders. If not, CHTs all around is pretty cheap insurance. If temps are hot or uneven, there is plenty written about how to get them under control.

overtorque Posted May 14, 2009 Author Share Posted May 14, 2009 Hi, My first post was a little bit incomplete... About the engine overhaul: After purchase, I wanted an accurate idea about the state of the engine. I opened it and I the situation was the following: - cam shaft pitted - tappets pitted - valves pitted - cylinders cracked: 3 with 8mm and the last one with 43mm As I wish to fly a lot and far, I decided to have my engine overhauled. About the reason to explain the cracked cylinders, I suppose that the previous owner use to perform high speed descent with throttle fully aft.... the plane is CHT sensor equipped, so it make me think about a fast thermic change that would damage cylinders. Now, I'm working on new electric installation and new instrument panel, I will post some questions about wiring and breakers protection.

Drew Swenson Posted May 15, 2009 Share Posted May 15, 2009 That is a good reason to OH---and I should have said CHT sensors on all of the cylinders---not just one cylinder. Quote Link to comment Share on other sites More sharing options...
