If you’re talking about the Mark 55 block, I had the exact same situation. Believe me, sometimes those pistons are just not going to budge, no matter WHAT. In my case, I actually cut the block off the piston. This was more a matter of determination than common sense; as I knew the crank would be no good too…..and it wasn’t any good. At least I got three good pistons and rods for my effort. Better than junking the whole long block.
As for the tool, it looks well made. I agree that the Shraeder valve may not handle 1000 psi but maybe you’re supposed to switch the valve and the fitting as needed?
Long live American manufacturing!
