So i was troubleshooting a slight misfire and pulled my distributor cap and noticed brass dust all over inside the distributor. Flipped the cap over which has less than 50 miles on it and noticed what you see in the pic. At first I thought ok the rotor must be rubbing the cap and shaving off the contacts, maybe i did not push it down all the way. So i put a new cap and rotor on and with maybe 15-20 miles i am already starting to see the same issue. Took a good look at the rotor and it looks perfect on both so i cut a cap in half so i could see the clearance to the rotor and it does not come close to touching anywhere. Does anybody have any ideas what would cause this? I do have an MSD 6al on the car but i cannot imagine it is blasting the brass terminals away. This is just a parts store Standard Blue Streak cap and rotor kit. Is the cap and rotor just cheap junk? Any help is appreciated!
