Any clue? Should I drain and return?
Nah that looks fine, just a little flaking. it will happen. if you don't notice anything beyond the gasket you should be fine. I have a few pits in my blocks, some are a little deepish, but not worries.
When in doubt, I like to connect the block up to a tap and put a bit of pressure through it. If water driven by a tap opened up fully doesn't seep through any of the gaskets you can be fairly sure they tiny amount of pressure applied by these pumps we run wont be a worry.
