Steve, I expect you will find little dzmage - free up the rings ort replace, knock the glaze off the cyl walls, and that should about do it.
As to the value of an oil analysis for this type problem - has no benefit that I can see. An oiol analysis might show excessive wngine wear from excess metal particles, etc. - but only then if the engine has several hours on the oil. A new oil change, with only a few hours would probably not show problems of excess wear, and would probably not identify the stuck rings..., or a burned valve.. Regards Fly safe - Have fun Harry
