Leak around nozzle

[Blob]

Hi

I am quite new to 3d printing, but I have a problem with what I think is a leak between the nozzle and the hotend.
When I am printing it seems like there is coming filament out between the nozzle, and after some time drops of filament is going down on the part that I am printing.

I have tried to remove the nozzle to see if I could figure out why it is coming. But I havn´t found out why.

Could any of you give me a hint about what could cause this problem?

When I replace the nozzle, should it be tightened or a 0,1mm gap between the nozzle and heater? Is there a guide for Pro3 printers?

Have a nice day.

Even new hotends need to be checked. I have 6 additional heads at my pro3. Not one has a gap between the nozzle and the headlock. Also the once added at the printer, also no gap. The gap is very important because this is the only way to be sure the heartbreak and nozzle are tight well together. Stuff provided by raise can’t be trusted, check yourself

I agree with Eric1960. I've been having a lot of trouble as well with hot ends directly from the factory.
