From reading some of the posts, it sounds like this has happened at other times as well. Does anyone know if it is the same rod all the time ?? There would seemed to only be three possibilities, lubrication problem, metalurgy, or design. At any rate, Rotax has got a problem on their hands. I can see the lower rod bearing going first in a lubrication problem because it "rotates" while the upper bearing just moves back and forth, on that basis I would pick lubrication. Also "rust" will cause "arcing" and pitting more so than bluing which again is back to lube.
