Distributor Squeaking??? What?

[badstang123]

The other day I noticed it sounded like birds were chirping under my hood. Naturally, I thought a belt or pulley. The belt was brand new but I tried dressing anyway and it didn't change at all. While doing this I put my hand on the distributor and noticed the chirp changed. By moving the cap it makes the squeak change. Now I figured at least I had found the location of the problem and could start from there. I went straight to the auto part store and changed the cap and rotor even though they weren't that old. To my dismay the chirp didn't go away. Anybody have any idea what it could be? It seems to do it more and louder when it's cold and normally goes away once the car warms up. The problem is it will do it even when hot sometimes too though. Any ideas or help would be greatly appreciated.

Have you wiggled the main shaft on the dizzy. All there is, is a single bushing on the dizzy. I would spray some decent penetrating oil down the main shaft and see if the noise abates for a little bit.

Good luck.

100% (well, 99.9) sure its the bushings going bad in the distributor. Mine did the EXACT same thing...and it would stop after it warmed up.

I swaped distributors and everything is fine. A reman. distributor should be under 100 bucks I think.

mine did the exact same thing, to make sure its that bushing though, just spray some lube down in the bottom of the dizzy and see if it stops like Hissin50 said. reman'd ones are cheap but it also gives ya a good excuse to get an MSD billet one

You guys were right on. Thanks for the help!

Mine did the same thing, but the squeeking quickly went to grinding. I would replace your dizzy.

Done

Glad you got it. That single bushing cant do a whole lot once it starts to go.
