What do you think about these case cracks?

I found these in the upper crank case when I was working on the clutch. They don't seem to be all the way through. Is this a problem if they don't leak oil to the outside of the engine?
If you click on the pic it will enlarge, than click on it again to see it even bigger.

Thanks,

Casting imperfections. They're everywhere, if you look hard enough. You'll find them inside the clutch side cover too. Don't lose sleep over it!

for Ed's recipe. It works -- unless you have drastic problems!

Thanks,

I've tried his recipe with no luck. I've got her running, just not that great. My troubles have been recorded on another thread.
