Oil inside spark plug holes on 2008 expedition

[ExpyOnly]

My expedition has 250k miles. The engine was running rough with a misfire code. I changed the spark plugs and coils and I found oil on two of the plugs and coils. After researching forums, others seem to say it's the valve cover gasket, so, I bought a new one and I'm now waiting for the parts to get here. But, my concern is how could it be the valve cover gasket when there are no spark plugs going through the valve cover. I got a P0302 code. And as you can see, that's the area where the oil was leaking into the plugs around cylinder 2. There was also oil inside the injector plug. Do you think replacing the valve cover gasket, plugs, and boots will fix this?

Did you get this resolved? What did you learn?

Hi, I also had the same problem with my 07 Expy, turns out it was the spark plug I was using and also the torque applied to the plug.
I previously used Champion 7989 (in order to avoid stuck plugs) but it seems their design allows some oil to get to the boot.

I replaced it for a Motorcraft SP-546 and it solved the problem.

Soooo ... The Sparkplug was the problem? You have an oil leak, no matter what plug you use you're still going to have an oil leak. SMH
