Wait, is this a BMX style one-piece?
So the chainring is held in position by a hole on the side, and the hole in the middle?
If so... is the chainring still round? Is it sitting snugly on the crank?
I don't believe it's your BB, I think it's something else. Sprocket or crank if you think your tension is good.
