Being that this is a dual plug head, are both cylinder 2 plugs in the same condition? Can you verify that those plugs are sparking? I would definitely put at least a fresh plug in the drivers side and see if it clears up the running problem. However...
The anti-freeze smell is very concerning, and very typical with a blown head gasket. Read this for some information...

I am still leaning towards a blown head gasket, but there is the (remote IMO) possibility that you actually could have a bad intake gasket. It could explain some of the symptoms that you are describing. The good news is that on the way down to doing the head, you pull off the intake anyway. If the gasket looks like a problem, then you might decide to put a new one on and see what happens. If not, then continue on down to the head gasket.
My main point here is that if you have a plug that smells like antifreeze, there is only three ways for that to happen. First, coolant leaking into the combustion chamber from the headgasket. Second, coolant introduced into the combustion chamber from a water passage from the intake, due to either a cracked intake or failed intake gasket. Third, you dipped the plug in anti-freeze before you put it in the engine
The oil soaking is most likely the result of the plug being fouled by the anti-freeze and no longer firing, leading to it then being covered in oil.
