    what would cause a distributor gear wear, where only 1/3 of gear is wore down to nothing, yes the other teeth are wearing about a sixteenth off tooth. This just doesn't make any sense to me at all? Picture 23.jpg Picture 24.jpg Picture 25.jpg

    If it is out of a chevy vortec a common problem. Dist. gear made of soft composite metal.
    Gets wore mostly on one side from cold starts.. oil pump torque..especially if not using 5w-30 oil in cold climate.

    What year? These gears are soft metal cheap gm gears. You need to get a melonized gear a steel gear that has been treated/melonized.
    Vortec have cast cams ...have to have a steel cam for cast cam. Cast ..gear for a steel cam. Can not run steel against steel or cast against cast.
    Will not last long . What engine 305 or 350. have part numbers .
