As I was cleaning my crankcase today, preparing for my rebuild I noticed a hole in the corner closest to the #4 cylinder. check outh the pictures. What are my options. does this need to be fixed. The only reason that I am unsure if it needs to be fixed is that ,unless it is structural, all it does is keep oil from entering the front cover from the crankcase. I don't want to have this fixed if I don't have to.
