Testing blocks in the home shop

[40 Deluxe]

My idea is to bolt on the heads and water pumps. Use short lengths of radiator hose with freeze plugs clamped in the ends to block off. Get a cheap leak detector kit that uses florescent dye and a black light. Use the dye meant for oil and mix with Diesel fuel and fill the block. You will need little or no pressure as Diesel is good at wicking its way through tiny cracks. Carefully drain the diesel fuel, pull the heads and use the black light to look for cracks.
