Nope, looks like part of the casting process

Nope, looks like . . . . .

    Well, the fact that you might not have any great experience with these may be what leads you to your impression; but what you are looking at is the parting juncture between the two case haves, which presents a small sum of material reduction on each case half, this as produced by the manufacturer. 

    Now, sometimes that edge gets mauled a bit by someone in a previous disassembly process, which might then no longer present as a clean straight line, or even just not so well executed scenario by the manufacturer, but it ain't cracked!   

    Not there anyway.

Not a crack. It's the parting line between the L & R sides. These are easy to work on Being able the pull a whole side off means you don't need to snake the parts in and out of the top (or side) cover. I circled the reliefs that aid in getting the halves apart.

This is the crack that I was specifically referencing.

Not a crack. Shadow of the relief machined into the case.
