Extruder prints fine up until further down the print So I recently installed a genuine E3D V6 (direct) on my AM8 (Anet a8 with upgraded frame). I have already been able to fix most of the print quality problems. But the last one is a hard one for me. 

It prints super fine up until a certain height. Then the extruder starts slipping and starts making weird noises like its clogged but I will be able to push through filament properly after cancelling the print. I thought it was heat creep but when touching the spiral heat break it is just a tad warm. I can comfortably put my finger on it and keep it there. 

I also tried two different brands of filament and it seems to happen roughly at the same spot. 

I tried PID tuning (the temps are literally perfect and super straight with no fluctuations), I tried cleaning the extruder gear and checked if it was worn or anything. Then I tightened everything on the extruder, making sure everything was nice and snug. 

I am not exactly a newbie when it comes to fixing my own printer and troubleshooting the problems but this one I have never seen or had before. 

Do you guys have any tips for me to point me in the right direction?

Running Marlin 1.1.8. I have a BLTouch on it and an AnyCubic UltraBase.
I used a different heat break with a PFTE lining inside. After that it ran smoothly. 

Probably what was happening was that my filament was getting too hot and started to stick on the full metal heat break.
