Bike noise, creak, click, creaks, clicks, clicking, pinging sound - help

Andy - i clean it regularly, and have cleaned it all again in the hope of the click mysteriously disappearing, but no joy.

Brett - i like the WD40 idea, much more up my street!

I hope the WD40 was a joke, keep that shit away from your bottom bracket. Its not a lubricante and will just make the problem worse.
