I had/have this problem too. when I tighten the left bb cup (plastic) it keeps turning, you can feel it tighten, then "fall off" as it skips threads. I think the creaking is when it works a little loose...
I am trying to source a replacement cup / cheap bb (penniless student), but in mean time I just remove left crank every few days and tighten the cup.
