Just one question what would cause the filament to turn yellow inside the heater block or the heat brake
Sitting there cooking for hours? Residue from printing a darker color?
What hotend? Some of the clone V6’s have bad heat brakes that can cause blockage. This desk like it was baking for hours though. Some serious discoloration
This is what PVC looks like when extruding pipe too hot and too slow… Not much of a comparison since we extrude 18" diameter pipe that can be as thick as 1.5 inches
Looks like it’s only where the plastic was directly in contact with the heater barrel (or PTFE liner, if there was one). Assuming it’s not some residue from another print material, it could be some additive breaking down from the heat, or it could be something from the walls leaching into the plastic.
I do not like to leave filament in the heated zone for long. I either extrude it or I retract it after a bit. Otherwise, I fear my nozzle will clog up and be a pain in the butt.

Sorry for the late reply
It’s a genuine E3d
I found that the ptfe liner has worn out somehow with some discoloration
A genuine E3D lite6?
@Whosa_whatsis e3d full
@Saud_Don_t E3Dv6 and v5 don’t have PTFE liners.
Yeah, if you bought an E3D hotend with a PTFE liner and it isn’t a Lite6, it’s not genuine.
@Ryan_Carlyle the ptfe that goes into the heat break
@Saud_Don_t A PTFE tube you insert from the top (bowden style) or a tube inside the heat break that you get to by removing the nozzle?
If it’s a PTFE tube inside the heat break that you get to by removing the nozzle, it’s NOT a genuine E3D.
@Saud_Don_t where did you get it?
Genuine or not, I do not recommend baking filament in the hot zone.
@Ryan_Carlyle
The ptfe inserted with the titan extruder on top
@NathanielStenzel
From the official e3d website
I agree I think it’s from baking in the heat block to often
