Lightbulb Changed my 43k mile plugs...

& here is what they look like. From left to right is cylinder 1 to 6. As you can see, cylinder 3 plug had oil on it.

What does the oil on plug 3 mean? Anything to worry about if only one of the "middle" plugs has oil on it?

Doesnt oil on plugs mean valve cover gasket might be going bad? Doesnt look to be much oil on the plugs so I wouldnt worry about it. I had same issue but it was with 3 cylinders probably gonna have to change the gasket soon.
