DonMuncy Posted September 13, 2017 Report Posted September 13, 2017 I was just reading my latest edition of General Aviation News, in which a reader, in a letter to the editor, states that during break-in of a engine he can hear not only the change in pitch when the rings become seated, but can hear each cylinder as it seats. Has anyone ever heard such a pitch change, or even heard anyone claim to have heard it. I would say he is exaggerating beyond belief, except that it seems that many people are a lot more sensitive in their perceptions than I am.
carusoam Posted September 13, 2017 Report Posted September 13, 2017 Interesting... I was hoping to measure a change in CHTs during the break-in process... No joy there either... My engine went through a few hours of break-in off and on the plane before I was involved. It probably was noticeable to a person that has done a few break-in flights... I'm pretty good at sensing valve tap on some of my older vehicle engines... does that count? Best regards, -a-

What a goofball, if the feds read that he might be going in for a Psychological evaluation
