Found oil in the spark plug housing?!?!!

[986FortyEight]

I hope someone has an opinion on this. Today I changed all 6 spark plugs with brand new Bosch plugs from Pelican parts, for the first time on my own. I diligently followed the steps documented in the Bentley and I did read many other "how to's" posted on various forums such as 986forum.com.
Imagine my surprise when a bunch of engine oil came out with the coil pack that's the closest to the front of the car, on both sides. The inside of the coil pack tube was free of oil but the outside was bathing in it. I did my best to absorb it with shop-towels and proceeded with replacing the spark plug anyways (perhaps a mistake in retrospect).

Upon completion of the task, I started the car to find that:
1-some more oil burnt off upon starting
2-Idle was a little erratic and after a few minutes settled somewhat but at least one of the pistons sounded like it was irregular, probably misfiring.
3- after 200 yards of test driving the engine light flashed a few times and then decided to stay lit.

I know that if a cylinder misfire the engine light is supposed to come on. I will go back and redo the entire procedure tomorrow to make sure I did not omit anything (but I torqued the plugs and ensured all connectors "Clicked" in place).

Finally the question: where can the oil be coming from?
What is the risk to the engine of me driving (to my mechanic - 10 miles) with at least one cylinder misfiring?

Any input appreciated!

Sounds like you didn't snug a coil pack enough or too much and cracked one.
Re-check em, if you read the code you could determine which one(s).

Bad or missing O ring on the tube? Maybe you fouled a plug installing it with all that oil you've described?

Thanks Sputter! I will check all coil packs again tomorrow.
I'm not sure I could have fouled the plug since I cleaned all the oil I could get prior to de-installing the old one and placing the new one in, but I will also check while I'm at it!

I am not sure about what O-ring you mention...

Hey bro,

Go to this web site;

It's Suncoast Porsche, once you see the tube you'll understand that you can change out yourself. With the plug removed you can grab the tube and pull it out and install the new one. Remember to lube the o-rings first before installing so you don't cut one and cause another leak.

Thanks man. The weird thing is that there was no o-ring on any of the tubes when I got them out...
and I still wonder where the oil came from...

Make sure they didn't fall off and are still inside the valve cover! I'd hate to have those floating around the valve train and oil galleys.
