Look what I found
My filament broke while I was changing it so I had to take the hotend apart to grab it from the other end. Since I had the hotend apart I thought I'd check the PTFE and it looked like this. So I replaced it. I guess it is worth checking this from time to time jsut to make sure it is OK,
Fortunately I have some 3/2 PTFE that fits my Ver. 2.0 hotend. I think I read somewhere that the Ver 2.5 version uses 4/2 PTFE which is much easier to purchase.

One of the more annoying things.

Indeed. After I got that out I discovered some melted/fused PLA stuck inside the nozzle. Tried getting it out with an unbent paper clip - that helped, but didn't do a complete job. So I reverted to the tried & true torch method - heating the nozzle w
ith a propane torch until flames come out the back (signifiying vaporization of the fused PLA inside) and the metal color changes from red to blue. Then it's just a matter of reassembly.
Fortunately this time I was able to re-use the same thermistor.
