Exhaust Valve Pic…….what does this mean?
I took my heat exchanges off to get them cleaned up and repainted. On inspecting the valves, I found cylinders 1-5 all looking dry as in the first pic. 6 however, looked a little "oily" and I could wipe a slight oily film onto my finger (see pic). Does this mean something bad is up with 6? I do get a very slight weeping of oil from the valve cover nut right below 6. My oil usage is very low.

That looks more like a bit of a rich burning cylinder...is it carbon or oily? If oil that isn't bad either.

Just put it back together and drive it.
I get why you're concerned but don't get bogged down in the details. No two cylinders are the same.

Just had my exchangers off as well. All cylinders looked fairly uniform to me. If this is a CIS car I'd check injector spray pattern/leaking/equal amount compared to other cylinders etc. What did the plugs look like?

Do a leak down, numbers may indicate a worn valve guide.
