Cruise Seems Lean

Ouch!
There is so much oil burned onto them I really cant tell what the hell is going on. At this point I would have more concern where all the oil is coming from?
How many miles on those plugs?

There aren't many miles but about 3 years on them. They are the original plugs I put in when I was getting it running. I believe valve seals are the issue. The engine has about 40K miles on it.
