Partial Answer Need some help with E3d v6 upgrade

im sick of toying around with my new hot end. I installed my e3d v6 from printed solid and it jammed on my second print. After speaking with them it turns out I was printing to hot so that's my fault but I took it apart and cleared the jamb. Now my the fan shroud is super loose. I tried installing it 100 different ways but still very loose. I used some kapton tape to tighten it a bit while the replacement shows up and now I installed the hot end and tightened the screws all the way but the hot end is loose. Is this a common problem? I'm not a fan of the plastic quick release plate in the least bit. The old metal one was so much smoother. Can I modify the old metal one to fit? Does anyone know why it could be loose?
