  Possibly a burned valve... However the "oily" plug leads me to
  suspect either a bad seal on your valve guide or a cracked piston
  ring... Unless it's just gas that looks oily. Hmmm, bad to worse,
  huh? Not to give you false hope, but I've not ever heard of just
  one guide go funky... Usually they all wear.

  I'd pull the head and have a quick recce. If it's a burned valve a
  new valve, a head gasket and a quick trip to the machine shop
  should have you on the road again quickly. If a burned valve is all
  you're looking at, have the shop reseat all your valves... It may
  also take care of that low reading in #1. If you're going to
  rebuild the engine at a later date doing the head now will be one
  less thing to worry about later.

Good luck

That's not a leak... My car's just marking its territory...
