    The heater block is leaking from the heat break connection. This happens when the nozzle is either the wrong depth or it's not making contact with the heat break tube in the heater block. It usually happens with PLA filament. Check to see if the heater block is wobbly while it's hot using a pliers. Never touch the heater block with bare fingers while it's running.

    If it is leaking above the heater block* then @BrooklynBay is correct. You have no seal inside the heater block. The seal between the nozzle and the heat break occurs inside the heater block. The nozzle being tight against the block is not a seal -- this is:

    This will leak:

    In this picture what they call the "throat tube" is actually the heat break (the real name) -- just to avoid confusion :)

    *and it really is, look at your first picture and you will see a puddle on TOP of the heater block. That means it is pushing up and out of the block and coming down the sides because it is not sealed inside the block (nozzle mate with heat break)
