Default Intake manifold leak...

I read online today that one of the symptoms of an intake manifold leak is wet (oil/fuel?) spark plug threads. How would a vacuum leak cause this?

I posted in your other thread also. I would assume you would see the plugs wet because the air introduced to the motor after the MAF would cause the O2's to see a lean condition and the PCM would add a ton of fuel to correct it.
