Kawasaki FH451V crankcase cover corrosion/surface cracking

I pulled the crankcase cover off of a Kawasaki FH451V-BS19 (installed on a Scag SWZ) to replace the PTO shaft seal and to look into some governor issues, and I found a lot of cracking on the inner surface of the cover that looks almost like corrosion of some sort (ethanol?). Is this normal for these engines? Bad casting?
