Just wanted to add a note about what's happening with my airplane. On my last flight I decided to ground my airplane because of the engine using too much oil and fouling the # 4 cylinder. I pulled the engine off and brought it home to work on.
This past week I was able to finally get time to get it apart. The # 4 oil ring was missing about 1/3 of it, other wise engine is in good but worn out shape. As far repairs, looks like I can get all new bearing, rings and gaskets and be good for flying. I have a friend in the local EAA chapter who is an engine builder to guide me along so I am hoping to be flying again before the new year.
