Flex seal will not help you. I see pcs of material missing on the “lower case” half. Wher the bolt threads into Buy new cases! Attempt to have somebody CLEAN, weld, drill and tap ur current cases. Try some kind of two part epoxy (not Jb weld) fill the area, tap and drill yourself. Good luck. The RTV/silicone(silly) is not doing you any good. Remove cover, clean well. Put greased paper gasket.
