I want to thank everyone who replied to my earlier questions about what to do with my aging engine. There was lots of sage advice. However, as I was getting ready to do a fall compression check on the engine I thought was showing borderline readings, I realized that my compression rig was out of whack. When I started comparing it to other guages it showed a 7-10 psi difference. I turned out that I was not getting 80 psi to the cylinder, which is why the reading were dodgy. Once that the tester was fixed I tried again, and found a very different situation. A valuable lesson learned. So now I am looking at readings of 70-66-69-66. Not super by any stretch but not in the "throw-away" range. The leakage in two cylinders is from the rings (you can hear it from the breather line) while the other two are rings and exhaust. My feeling is that while the engine is a bit tired, it is not ready for major work yet. Perhaps next year. I was wondering what experience others are having with old continentals as far as compression. I always value the advice from the list, because it gives me a sense of what others in with the same airplanes are experiencing. I will be seeing advice from local mechanics as well, but no one knows there small continentals like the operators.
