Robert Hicks Posted September 9, 2019 Report Posted September 9, 2019 The saga continues. Some of you may recall my leak at the base of the #2 cylinder. Suspected a crack near the bolts or undersized bolts. The hot weather finally took a break here in Phoenix and I was able to get to the hangar to remove the cylinder. Everything looks good to the naked eye other than these gouges where someone prior allowed the rod to smack the case. In the groups opinion, would this cause a significant leak? I would also add the top is the same. Thanks again for the input. Sent from my iPhone using Tapatalk
takair Posted September 9, 2019 Report Posted September 9, 2019 That one at the left, that goes from inside to out, seems like that could cause problems. The others could be stress risers for future cracking. Not sure what Lycoming says for repair...
Robert Hicks Posted September 9, 2019 Author Report Posted September 9, 2019 Thanks for the reply. Engine is close to tbo so we’re gonna pull it and overhaul. Just wanted to get some guesses on the problem for closure I guess lol.Sent from my iPhone using Tapatalk
Yetti Posted September 9, 2019 Report Posted September 9, 2019 You can see where the O ring has worn into the scratch. The O ring probably is damaged. 100W is really good at getting out of the engine. Put a new starter on it.
