Pulling the head today on a '94 1fzfe and went to put the service bolt in the exhaust cam gear. There is, what appears to be, a dowel pin in the hole (left hole in the picture). It's far enough in that it doesn't contact the outer half the cam gear. Nothing about it looks like a sheared off bolt. I pulled the cam as is - the gear didn't move. Any ideas what's going on here?
