I don't know whether D-B's design of the valve train intentionally made the rockers sacrificial elements, but that seems to be the case. Differences in the level of case hardening of the lobes and rockers leave the lobes dimensionally close to standard while the rocker contact faces wear more rapidly. Though there are striations in the cam lobe contact area, just replacing the rocker returned the lash to an acceptable level....for now.
