Well, the seller contacted me today and said that it is too much of a hassle to return set up a return of the CV13S and that I can keep just keep it. I am guessing that the engines are quite similar and that many of the parts are interchangeable. I do not think it would be fair to turn around and sell it so I think I will just put it up on the shelf to have some spare parts to pull off of in case I need them.
I did just notice in looking a bit closer at these pictures that the side of the cylinder wall appears to have a chunk taken out of it. i guess this engine is toast!
This is true. Your "connecting rod" has become very dis-connected.
If you read through the whole thread you will see that I was having an issue with a the lifters when all of this started happening. I am not certain as to what it was that lead to the final (catastrophic) failure, but I can say with 100% certainty that the engine was not over-revved, the oil was clean with no evidence of water or fuel in it. It is entirely possible that the collapsed lifter that I suspected was causing my "ticking" sound in the weeks prior to the failure lead to a more serious breakdown should the air/exhaust valves stopped functioning properly. What leads me to believe this is that just before the failure the engine started bogging down with a very noticeable sound in the exhaust note and when the engine was turned off it stopped with a loud "clank" or "clunk" which was likely the moment when the rod made contact with the cylinder wall and camshaft. Regardless, the failure was not a complete surprise as the engine was already exhibiting some issues that I was attempting to fix but was obviously not successful.
