#8 plug fouled

while redoing my header gaskets, i found that the #8 plug is fouled, but i dont know if its oil or coolant. the engine is rebuilt with about 3K miles on it. i have no idea how long its been this way. it could have been from the initial startup and break in. im not burning any oil or losing any coolant. ill get a pic of it tomorrow and post it.

any ideas ? im thinking its an intake gasket leak.

Doc here,

What color is it?

Black=too much fuel/air mix
white=too lean
glazed black=oil fouling
rusty red=normal
wet..and not flammable=water..
