Going back to way earlier discussions on Valve Lash on a 06 GV. I am puzzled with what I am finding. As an example; I show the gap between the shim and cam is larger than spec (.356MM exhaust - measured) , but I am showing no wear or very little (<.005mm) on the shims (based on the stamped shim #). This doesn't seem to make since, I would think they would get tighter not more loose. Does something else wear, bucket or valve stem? Spring get weaker? I have double and triple checked my measurements. Any insight you could provide would be greatly appreciated.
