Burnt Oil on Spark Plug

[CapnSpaulding]

I changed all my plugs today and they all looked great except for one. This one was the closest to the firewall on the driver side. It looks like burnt oil, but wanted your opinions. It was not wet at all, and smelled more like burnt plastic than oil, but sure looks like oil. The only other thing to note is that I THINK the ignition coil gasket was missing on this coil.
I never noticed any issues, but replaced the coil anyway.

Thoughts?

The tip of the plug looks like it has been running fine. Apparently you have a leak in the valve cover tube seals allowing oil to leak onto the exterior of the plug. Time to replace valve cover gaskets and tube seals.

^^^This. You need new tube seals and will have to replace valve cover gasket anyway. Might want to consider replacing PCV valve, grommet, & hose since you'll already be working in that area

Thanks for the info!
I’ll add it to the list, I have the pcv valve, grommet, and hose on order already. The valve was bad, the grommet was missing and the hose was cracked. Poor thing, I’ve only put 200 miles on it since I got it, but I’m surprised it ran so well considering this and the corrosion on the plugs. They have close to 200k on them according to the service records and PO.
