Used the product. The sealing washers for bolts are junk at best. Went to flat washers and sealant on the bolt threads. Still got a few bubbles around the bolts. It got the job done by spraying soap and water all over. Used expandable rubber freeze plugs to block off the valve pockets and exhaust ports to hold water and look for leakage. The product will work you just have to be creative. I will use again.

I'm glad I purchased this!

I used this tester to confirm my worst fears on my flathead engine I had purchased already built in a 51 Victoria. Two cracked cylinders! Very impressed with the tester as it came with rubber gaskets on head plate and water pump plates as well as bolts with sealed washers. Good quality construction!

Built a lot of Flathead motors & after all the machining + putting it together only to find the block was cracked inside #5 exaust port. Should have bought this pressure tester years ago. Only bad thing is the pressure gauge didn't work.
