Close Inspections . . . Hmmm?

The left-side case bolt threads into this boss on the right case across the front cylinder base.  It's already been heli-coiled down in the hole farther.  The threads look solid and good.  I'll probably leave (as is) since trying to fix it may create a mess?  The case needs clearance for the connecting rod anyway.  (that's why it's so thin in the first place) I'll just be careful with the case bolt tension on reassembly.  I may smear it with some red glyptal or The Right Stuff . . . .
