First of all the spark plug grommets should be on the plug before you put it on...
As to the OP, just change all the plugs and your valve cover gasket and it will most likely solve your oil drenched plug problem. Good luck. Lmk if you have any other question. Problem is common when the engine gets older.

No way. The plugs are screwed into the heads! If you are getting oil on the plugs with them screwed in, you have 0 compression and major issues..

Has anyone replaced their valve cover gasket and seen the problem stop? I agree that it is the valve cover gasket, but that would prove whether you had no compression or just a bad gasket.
Bugjug- I can't imagine a motor running if all 6 cylinders have no compression...it would be very noticeable and not a surprise when changing spark plugs.
I have run into the same problem with my SC, and was really nervous today until I talked with a buddy of mine who happens to be a technician and an owner of an FD3 and MKIV Turbo... He told me it was fairly common on higher mileage vehicles to see that.

Ok, so I just finished replacing the valve cover gaskets and while there replacing the plugs with NGK Iridiums. The difference is AMAZING! I bought this car about a week and a half ago from a dealer thinking that the car likely had some big problems...oil loss...unknown rattle under the hood...etc. Well, when I went to remove the valve covers, I saw immediately figured out the problem - all of the valve cover bolts were loose! I couldn't believe it! So once I replaced everything and fired the car back up, the rattle under load was completely gone. I also had a noticeable increase in the power of the car due what may have been the car's first spark plug change.

I also felt the power difference when I changed spark plugs and spark plug wires. The car feels much more responsive and butt dyno says about 5hp gain. 
I also changed valve cover gasket and after applying proper torque, the engine seemed to have significantly less vibration. This maybe due to most of valve cover bolts loosening to hand tight tightness prior to the fix.
Now, about spark plugs drenched in oil. I also had oil trapped in the valley. It seems it's a combination of oil spillage when adding oil at oil change and oil leaking from valve cover gasket.(when I removed the old gasket, it was still somewhat flexible unlike how other member has described as cracking and falling apart. This leads me to believe that in some cases, valve head gasket leaks due to loose bolts and just needs tightening. **I did end up replacing them with new ones anyway, since I was in there.)
Note how gasket is still in tact:
However, due to loose bolts and possible bad gaskets, oil was everywhere:
Nasty valve cover:
I used fel-pro gasket set:
The set included rubber seals/gaskets for spark plug cover. The old ones were hard like plastic and just fell apart. New set should have a nice tight seals against possible oil spillage next time I change the oil.
Then I did the other side and also installed new spark plug wires:
All finished and cleaned up a bit:
