Seems like the J-head is melted...you can check the inside of the peek J-head, see melted or not.

No. The J Peek it's perfect. The stain that you see over the nozzle is black PLA. The problem, I think is that the nozzle is completely blind. There's no hole for extrude PLA so the filament needs to get out for anywhere.

Clean it up and do you see anything different?

After several cleanings and printing tries, I think I'm ready to give up...

I think you can take a picture of the "blind" hotend and contact the seller to replace it .
