when using a roller cam you must use the right distributor gear know the makeup of cam core gear. GM roller steel cam core needs a melonited distributor gear. after market all one pc steel roller core use a bronze gear .if a two part cam core with iron gear pressed on core or a S.A.D.I/Proferal core. stock iron gear .i never seen a gear fall apart from oil only . but added oil can be done by clocking #5 cam bearing oiling hole up to 12:00 clock . drilling a drain back 1/4 hole by boss of dist in back of block. use a Msd distributor has a gear oiler use the added o ring .work will need to be done to block . roll the dist boss in the block so O ring will not get cut . if the wrong gear was use on the distributor a cam core that was not made for the gear. things will not get along . cam end play is a big deal with a roller and checking the cam to dist contact pattern all plays in to how long a bronze gear will last . the make up of bronze alloy plays in to it as well as a HV oil pump
