Hi Folks,
I have a cylinder sitting on a shelf collecting dust. It generally appears to be in useable/rebuildable condition aside from some damage to the two cooling fins closest to the rocker cover. It appears they've been dressed down in a triangular fashion. One fin is missing approximately 2" of its outer edge and the other about 1" with both having approximately 1/4" missing where they meet the cylinder head.
Searching online I've seen some mention of manufactures repair limits based on fin area or length but I've not been able to find any actual references in the usual places. Anybody know of guidance from Lycoming (or any other OEM out of curiosity)? Failing that, any unofficial wisdom on the topic?
Cheers,
Jeff
