how dirty/corroded can you rotor be?

[BehindtheHead]

i pulled my cap off this week and there was a touch of corosion on each of the cap terminals and also on rotor.

also who much of a gap is inbetween the rotor terminal and the cap terminals?

Not a whole lot of gap there. I also havent seen a cutout of a cap/rotor on a distributor so Im not really sure. (sounds like a good project with all the old chevy stuff laying around)

I guess if its dirty at all I always replace it. Usually they are pretty cheap and its not a bad idea to have good new ignition stuff on there.

I'd just replace it if it's startin to grow stuff in there.

Yep. If cleaning it does not work, it is so cheap and easy to replace most of them it is no contest

fumundacheese as I recall an old mechanic friend of mine used to call it.

Pretty dirty!

Honestly I have never thought about how much gap there is between the rotor and the posts of the cap!?

Just for the heck of it go back and read the first post but forget that it's in the auto forum. Well it was good for a laugh by me, but look at the time!

If there's any crud, replace. You risk leaving residue behind by trying to clean and that can lead to tracking/arcing in the cap.
