/diy/ - Do It Yourself

I got a new creality ender and suddenly it started having feeding problems. The filament stopped every so many centimeters(observable because the extruder cog created deeper crevices like the filament couldnt advance). I have taken the hotend apart but I havent noticed anything clogging it.

The pfte tube It seems it has been deformed(and despite taking out the filament there was still a small piece at the end but idk if thats normal) and now I cant put it back together because the pc-4 neumatic tube(the top part of the hotend that acts as a brake for the pfte tube. Thats how google seems to call it) but idk know enough to say if that is normal or Im doing something wrong so I added pic related.

Should I get a new pfte and pc-4 then?
