I had another look inside one of my cylinders with the new Ablescope today. One the piston, i see these two little raised thingies (I don't know how else to describe it)... see the picture below. What am i seeing here?

Here's another look at another part of the same piston... is it normal for piston faces to have so much crud on them?
