I'm using a Streamlight LED penlight to look inside the water jacket. These things will put a beam into places a shop light can't touch. I keep it in my pocket whenever I'm in the shop. It is amazing what good light will do for ancient eyes.

There is no casting sand or debris in this block anywhere that is viewable from the holes in the deck. As I said earlier, the block was cleaned from every access with a 3000# 4 GPM pressure washer before going to be dipped.
