Yes the PTFE can become distorted cause your delima, Have had several filament throat Barrel PTFE liners go bad.
Been told that if you change from PLA to ABA and back to PLA the different materials leaves a residue this causes the filament to get stuck in the Nozzle.
When replacing the throat Barrel make sure the barrel is screwed in far enough so when you screw the nozzle in it rest on the barrel,
as a gap between the two will lead to a similar problem.

I just replace it with a new block they only couple of $ of ali.Quote

I was warned ahead of time about the "gap between heat-break and nozzle" blockage, so I checked that out too - This block is so huge that there is a space in the center that each end butts up against to make that seal certain. But the threads are crappy on the heat block so I use Teflon plumbers tape to try to seal that.

the 280C came from the notion, had to tighten up some degrees above what you gonna use the hotend at, so if you at 260 with abs 280 doesnt seem to bad you mind if I ever quote those four steps you explained it so much better than me.Quote

As per @Jinx, you need to assemble the hotend while it is hot. I don't think it needs to be at 280C though... I just do it at normal printing temperature.
