This sounds bizarre, but I have a Delco points distributor with a Pertronix inside it in my Oddfire and there’s a noise coming from the cap. Like the rotor is rubbing the terminals but there’s no evidence of it on the inside of the cap or rotor. When I first installed the rebuilt distributor it made this noise and after retiming it recently, it is making it again. The tighter I tighten the hold down on the base, the louder it is. If I leave it almost loose, it’s almost undetectable. I can’t remember fixing it last time, but it did go away. I have been thinking of buying an HEI style anyway, but I’ve had great luck with the Pertronix in this one and I'd like to keep it around for a spare if I get an HEI. If it's a spare, I'd like to be sure it was up to snuff. Do you guys have any ideas what this noise could be?
