I like this. Sounds like it would be hard to miss a crack with this system. I would still use rubber head gasket and dummy water pumps. This way I'm only testing the block. Amazon has a Mastercraft UV test kit with everything needed for the test. Price is 60 bucks. I have used trailer balls in the past to cap off hoses on my run stand. BUT... With Mark's 55 psi in there the block better be filled with liquid and not much air. Think 'potato cannon'.....
