As reaping miner posted, it seems to have solved at least part of the problem

As to the 'pop', when you extrude a length into mid air, does it feel nice and smooth when you run your finger over it, or does it have rough spots? If the latter, then you need to dry your filament.
So i have been printing for a while now using a PTFE lined barrel (Friends E3D V6) and no more extrusion problems! (Well i do have one "under extrusion" problem. But i do not believe this is related to the hotend.)

I suspect the pop might have been some chloroform residue in the nozzle and/or some trapped air in the melt zone. I have cleaned my nozzles the day before. The extruded plastic is generally a smooth line after the hotend is primed at the start of the print.

I do have a different problem now which i will describe in a different topic as i believe this is unrelated.

Thank you guys!
