I replaced my rotor in my dizzy about 2 weeks ago, as a routine service. When I took it out, the plastic that surrounds the metal contact area base was burnt away in spots. I hadn't ever seen anything like that before, but just thought it was old and **** happens. Well, yesterday my car was running rough. Checked plugs, wires, cap, and when I got to the rotor - looked worse than the one I remove 2 weeks earlier that had been in the car for 6 months. I am going to try and get a picture of the rotor on here, but I'm not sure when I'll be able to. Anyone got any ideas about excessive rotor wear? Ever seen this before?

Here's the ignition setup:
MSD SCI
MSD Blaster SS Coil
MSD 8.5mm plug wires
NGK 2 heat range colder, non-resistor plugs (I have a turbo(heat range), but is the non-resistor part right?)
MSD dizzy cap

All of this on a d16a6. I've never had this problem in the past. Is it the non-resistor plugs? What plugs are everyone else using? At what gap?

Thanks,
JB

 

yeh dude that happened to me too! it was on a jdm first gen b16 motor, tho. I got stranded on the border of IL & WI because of it It melted the rotor, and it girated 180 degrees on the shaft....causing my ignition timing to be way off.....my car shot flames out the exhaust and died. anyways, my distrubtor main bearing was seized i guess. When we removed my dizzy, the part that spins and goes into the head and into the intake cam (on my DOHC motor....probably just goes into your one cam) was barely able to be spun. Trying spinnning it with your hand, if it has almost any resistance at all, the bearing is bad. It should spin VERY easily. they do sell rebuild kits......but i didn't wanna chance the problem returning. I purchased a distributor for $200.........no going to honda or junk yard for a dizzy for me seeing as how there never was a NON-OBD (OBD0) B series VTEC distributor in the US. i would just go to the junk yard, and pull one off of a 4g civic si/2g crx si. hope that helped

It would seem you are passing a lot of current through the rotor to make it melt. Ideally you want high voltage but very little current for a spark system. The non-resistor plugs aren't helping the situation. Are your plug wires non-restive too?
""I've never had this problem in the past."" ... Does that mean you recently switched to the non-resistor plugs?

 

its probably your dist. bearing, rebuild or buy a new dist
