I made water pump block off plates with a gauge, used heads and head gaskets. I used a bicycle pump to pressurize a water filled system and looked for leakage the next day.

I also pumped up with air only and submerged it in a big plastic tub over night and found no bubbles or burps. Gauge held steady.

I did find the typical "part number" cracks with dye penetrant and that was it. I was lucky.

If I did have bubbles or water leaks with this setup I would not be able to look into the cylinders but, I WOULD know there are cracks to investigate.

I made my test kit with what I had on hand.
