if the 24V heaters weren't so expensive I would just chunk it also.

So two heaters for $5 is expensive? Where are you shopping at?

Can not tell from the picture if the throat is loose or crack. heat up nozzle and unscrew the throat, if the throat is intact, burn out the plastic, cut a piece of alumium foil to washer shape put between throat and heatblock can help stop leak.screw in throat and tighten when nozzle is hot. hopefully this will last until your new hotend arrive.

if the throat is loose, most likely cause is the heating element wire is not tied right, when your x-axis move back and forth, the heating element wire constanty attempt to unscrew the heat block from throat. zip tie the heating element/themistor wire at at least two spot on hotend can greatly reduce this.

I have about 120 hours print time on this nozzle and all of a sudden i saw this. it is torqued to 30 in-lb.
I think that is the max torqur the aluminum block will take. what else can I do to keep it from leaking.

Thanks
