79 280zx ignition coil hot without running

I'm trying to get this car started after 2 years of sitting. I noticed the coil gets too hot to touch after sitting for a few minutes with the ignition on. I know the get hot but this seems strange.

Not sure if this is heat related or not but just noticed the coil is leaking from near the top. Guess I will replace it.

Will a bad coil overheat? I would hate to replace it then burn up another one.

Sounds like a shorted coil which then cooks itself. Leave it alone until it explodes and then replace it. lol. Coils do get some warmth to them but not so hot you cant touch them. An old coil might short out some windings in time, get hot, more windings short out, and it just gets hotter until its dead
