    Australia mate fair dinkum.
    on a brand spanker belt you will need to turn the sc pulley around by hand, porbably safer than using the motor. You should not have an extra groove. can you get a pic.

    to block the bov you need to make a thick metal cover plate or buy one, remove the bov, attach the plate. give the bov to the dog as a toy. You can block the hole on the air box if you wish.
