SORRY TO HEAR ABOUT YOUR BAD LUCK CLOIS......
I really think you have to focus on the root cause here. If the crankshaft is blue or discolored you may have
oil starvation issues...if on the other hand the color of the crank is okay you may have had a rod bolt fail or stretch out allowing the bearing to spin and fail....look at the back if the bearing or if that's destroyed look at the inner diameter of the rod itself......if it appears that the bearing has ground away the rod then you have excessive clearence or rod bolt problems.....these things are 99% close inspection and common sense to determine the source of the failure.......
Good luck and again sorry to hear about another dead FE.....on the other hand George is a great source of info and willing to help.
