your question has the answer to your problem: "the aluminum case just above the slit in the drive is a bit bent down (it is convex in the middle)"

if you bent the case and maybe the top of the optical drive too - than it would make most likely the problems you experiencing

remove the optical drive and look if it's bent - try to fix the bottom case (very carefully)
