Default Spuddering/Misfire

I recently had my valve cover gasket replaced because it was leaking. I got the car back and it was fine for maybe 2 days. Now my car is misfiring/spuddering at low rpm's. Once i get the car going past 2500 rpms its fine at least i think.

Today it got worse with the spuddering. So i decided to pull the Coil on the cylinder furthest from the fire wall and found that there is oil at the bottom of the tube where the spark plug sits along with oil on the Coil that goes down to the spark plug ( I didnt Pull the spark Plug). I also pulled the coil right next to it and same thing. so i assume thats the problem. Do you guys think thats the problem? Is it likely that the valve cover was not fitted correctly and the seals are not sitting correctly for the spark plug tubes? Any help would be greatly appreciated. Should i expect the worse? i will be taking the car back to the dealer on Monday. Is it safe to drive it?

here are some pics

I would say the oil in the plug shaft is obviously from a bad seal on the valve cover gasket on the plug tube. I had this exact problem on an Integra I had. I replaced the plug and cleaned the wire well. I pulled the valve cover and cleaned the seals, applied some honda bond, put it all back together and she was good to go. I hope this helps, even though it's kinda stating the obvious.

who did it? Definitely the spark plug seals were put in wrong, pinched, or weren't sealed right. I wouldn't drive it to much until it gets fixed

I would agree with ^^, seems the spark plug seals weren't seated correctly.
