Nah its not the banjo which is cross threaded its the actual lucky doughnut.hmm i getya now! ok not to worry you need to remove the banjo and re thread it! smartparts metal is made of clouds! once you have got it re threaded you need to wrap ptfe tape around it if that doesnt solve it look on the forums for random ion spares or get in touch with mk1 he might be able to get you a spare!
