I have recently noticed that my distributor will make a clicking noise when revving the engine. The clicking/buzzing will not stop until you rev at 2500 to 3000rpm for a couple of seconds. I recently was having problems with backfiring and sputtering and changed timing. Timing was retarded almost 10 degrees to far. And this was done with SPOUT unplugged. It is now set at 10 BTDC as manufacture specifies. It seemed okay for a couple of days, but now buzzing and backfiring are starting again. The rotor button and cap hae been replaced no more than 4 weeks ago.

Thank you.

Ticking noises from inside a distributor are nearly always the result of the rotor hitting something as it goes around. I would pull the cap off again and inspect it carefully and make sure there wasn't any contact that bent the rotor tab or anything like that. If the cap wasn't seated securely, that will happen.

I took it off and reseated the rotor, but I will check it tomorrow. May just get a new one to eliminate it. I hope that is all it is. Would a wore out distributor cause that problem?

Thank you.

Yes, that is possible, but not the norm. The distributor uses bushings where the shaft spins which gets oiled automatically from below. If they run dry, they tend to make a squeaking or chirping noise. The clicking is usually the result of something making contact as it spins.

Modification to original post.

The buzzing/clicking does not start until it hits around 3000 rpm. It does not happen at idle. I am still looking for a bent rotor. I cannot work on it until this evening, but do I need to check for anything else?

Than you very much for all your help

It's always possible that the distributor bushings are dry but you can't see that. You just have to listen through a stethoscope to determine that.

I was able to get around to messing with the car today and put a new rotor and cap on it. If you rev to 2500 to 3000 it starts clicking/buzzing. I checking the distributor shaft and it looks like it has a little bit of play side to side. Does this mean it is time for a new distributor?

If you can be sure the noise is actually coming out of the distributor, then yes it should be replaced.
