Spark plugs @ 90k miles

I'm concerned about the build up on the base of the threads. one plug had wet oil on it, but the coil and o-ring were dry so it's not leaking from above the plug and dripping down.

Could just be old anti-seize. The electrodes look fine, they're not all gunked up.

Did you post pics of the oily plug? The ones you did attach don't look too bad.

thats what I was thinking

That greyish stuff definitely looks old anti-sieze, but I'd be concerned about the 'wet oil' that looks like it's gathered on the stop ring on that first pic. Maybe what TBJ said?

I didn't see any oil leaking, however, the oily plug came from the passenger side, but now I forget if it was the rear plug, or middle. I didn't look real hard for a leak since the coil and o-ring around the coil were dry. Next time the hood is up, I'll look closer.
I didn't use anti-seize when I changed the plugs the 1st time. This is only the 2nd plug change, the 1st didn't happen until 60k. (FYI:60k on OEM plugs, not recommended. They were in bad shape)
