mate these are $180 new from toyota, and the rarest part in a 2TG!! I've got one spare, its the basic sort, would want $80 for it but (engines useless without it). will fit a #220 head. It came with an engine i bought (bought it mainly for the cams and tensioner), was supposed to be working but i personally haven't tried it on a running engine.
Also got a broken one, it broke in half but could be welded back together.
