It’s worth noting that some but not all combinations of heat break, nozzle, and heater block require re-tightening at the temperature used for printing. Basically, different metals expand different amounts when they’re heated, so if the block expands more than the other two, a gap will open up between them, and melted filament can find its way through.
Yes and on some printers, that spot where the Bowden tube meets the nozzle is very problematic. You have to loosen the nozzle a bit, push the Bowden tub up against it, then tighten the nozzle the rest of the way
It was awful on my Ender clone, but haven’t had that issue on my Prusa.

Good to know. I’ll add that to a check list to go through every now and again
