Dear Mr. ygaabofm
Sorry we couldn't help you. Have you tried asking NASA?

All these replies and not one serious answer.

Let me rephrase the question.

On the Big Lycoming engines, at what compression reading would indicate
a
need for an investigation. In other words, what compression reading is
considered a warning sign?

On a Lycoming O-550, at what compression reading would you start to
consider
doing a top or complete overhaul?




There is no such engine.
