The block has to either be custom, or has been taken appart and incorrectly put back together with the o-ring missing or improperly placed. Leaks usually occur on the fittings, not from the block itself and not this dramatically

It’s an EK block. By default, unless you get an AMD specific block, comes with the Intel mounting plate installed. To install the AMD AM4 plate, you have to disassemble the block and reassemble it.
