those are nice rods !! never seen an issue with them my self as well,
as for the leak , i was looking at the carbon (black ) soot , on the rear of the gasket , may may not be what i see just looked funny compaired the the front
also , the center pistons alfull clean , ?? have you discovered why ,, or did they get cleaned up ??
i could be wrong was it #v 5 rod bearing there looks like it got hot on the crank?
never like to see this as i have several times allready, but but i do use for future education, if it was an oiling issue?? how do we , fix it and where was the issue located , and a cure, so we dont repeat
i ask because we all need to know exspecialy if it an issue we all can look at an repaire before any more carnage
thanks
