Threads are wet. That indicates oil in the plug wells. That indicates a poorly sealing head gasket around said plug wells. Tighten head cover to proper specs in proper order. See if it helps.
And do something about that extra gas. You are running pig rich.

EDIT: If the valve cover seal is leaking. Shouldn't the top part of the spark plugs be covered in oil then? At least some?
Thanks for the help.
Valve cover got replaced along with cam-gasket, waterpump, belt etc. But that about.. .wow.. Time flies! 5 years ago maybe. I did tighten the valve cover according to this book. and I did use the correct torque.
I've got a spare gasket, so I'll swap it asap and update this thread, so that people with the same problem can find this thread in the future :-)
BTW: Isn't it easier to change the CAS O-ring when the valve cover is off ?

The top part of the spark plug is mostly covered by the wire boot. They tend to stay clean. That's least of your worries though. Also, you need to retorque the valve cover bolts after a few drive cycles I have found.
But yeah, you are either running pig rich everywhere or burring a good bit of oil.
