Looks like a head gasket leak. Notice the oil around the threads on your plugs.

You mean valve gasket, not head gasket.

everyone said it was the valve cover gasket because there was oil at the bottom of coil packs #2 & 3. I cleaned out the oil that had built up in the holes and the oil hasnt come back for about 4 - 5 days now ? im hoping that it was just oil that was carelessly spilt while doing an oil change. There was tons of evidence of spilt oil under my engine cover ...

What he said. I wonder if mine were replaced and I don't have a record of it because my car has close to 75K miles now and when I replaced them on Sat. they didn't look anywhere near that worn. You running a tune?

Changed mine at 60k and they looked a lot better than these however the color is right on, so that's a good indication that your engine is running well.
