Folks, I'm in Athens, Georgia (AHN) and we're doing an annual on my 1969 Cessna 150J with Continental O-200 engine (about 1950 smoh, 500 stoh). Compression was low on one cylinder 80/62 and that one seemed to be leaking out the exhaust valve. The rest of the cylinders were 80/76 80/77 80/77. We started pulling cylinders, yesterday evening. #4 with the low compression has a broken ring and pretty worn bore. The one next to that seems to have head cracks, bore pretty good. Other side front looks pretty good and one is still on the engine. Oh, yes, in the middle of all this we pulled the shrouds off the exaust....the cabin heat side has about a 4 inch long corroded, rusted through crack in the pipe and would definately be a nice source of CO into the cabin when using the heat. (and I remember using it as recently as May, even here in Georgia) So, my IA, came over to take a look. After pondering and poking here and there, he announced, "You have a crack in your crankshaft." He pointed to a spot on the back of the prop flange. He went and got his magnafluxing gear and we pulled the prop. Under the blacklight we could see a crack about 1/4 of the way around the hub. So, I guess I'm looking for an O-200 crank (mist pass approval of my IA and be yellow tagable by an engine shop. or a decent engine with logs or even a bottom end with logs or even some cylinders. Let me know what you have or know of. I'm also interested in your suggestions at how to proceed at a reasonable cost. So, even though your engine runs fine....IT MIGHT NOT BE!!! and inspect your exhaust system.
