Coil packs don't need to be replaced unless they're obviously bad.
I've had that happen to me once before. If they are mixed with oil because of a failed spark plug well grommet as you showed us, just clean out all the oil using an air compressor or a straw and a (children's over the counter) medical syringe to purge the oil out of the well. Any little bits of oil remaining, I'd let drip into the chamber. Yea, you'll burn oil for a little bit, but so long as it's all sealed up properly, it won't be for too long that you'll be burning oil.
