I might get banned for suggesting this. Here goes. So If I drained the coolant, wirebrushed the area, applied denatured alcohol, and then spread very carefully some JB weld onto the area, and let it dry for 3 days minimal would that work? Keep in mind its barely even a drop or two after a ride right now.

That would temporarily stop the oil leak but the cylinder will continue to crack until the crack propagates from the base basket surface to the reed gasket surface on the right side of the cylinder.  When this happens the left side ear of the cylinder is carrying all of the load on the back of the cylinder.  The area where the left rear stud anchors into the case will usually break.  When this area of the cases break where the left rear stud anchors, your cases are junk.  I have not been able to successfully repair the left case when this area breaks out. 

No need to drain the coolant.  The crack is not leaking coolant.  It is leaking oil that was in the fuel. THERE IS NOT ANY COOLANT CLOSE TO THIS AREA WHERE YOUR CRACK IS LOCATED.
