Is this cap dead?

I can’t measure it unfortunately because it came out of my meter

 

[BuddytheReow]

When in doubt, throw it out!

That's a spark gap, not a capacitor.

 

[passtheducky]

Ahhh, thank you!

When your caps are so old and crappy that they crack in half — of course they're gonna throw a spark across the gap!

I've never seen caps that bad before.
