2009 CRF250R left case problem

I have an 09 CRF250R that is turning out to be a major POS. I had the left side cover off to inspect the screen and noticed a questionable area in the left engine case. Behind the timing chain the case looks a little porous near the cank bearing and the bottom uf where the cylinder head studs would be. It tried to take some pictures of the case but did not turn out, anyone ever see problems in this area.

How bad does it look? If it doesnt leak, i say run it. If it bothers you to much buy a new engine case or rig something up with JB weld. There are lots of threads on here with people fixing cracks and even holes in their engine cases with JB Weld
