Default Cyl 7 Misfire I found the issue! Now what

Hi all. I've tried searching this forum prior to asking this question and hope there's a simple answer. Had P0305 and P0307 errors and by reading the forum, I replaced plugs (B +4) and wires (magnecor 8mm). In the process of changing plugs, I found oil coming from the valve cover right above cylinder 7. That original plug was fouled and the others looked better. I've tightened the valve cover which has stopped the leak.
Now, how do I get that pool of oil out from under that plug?
I know that I'm assuming the oil is from the valve cover leak, so let say for this moment that's what it is.
FYI... After replacing the wires and plugs, P0305 was gone and P0307 is not as often. At highway speeds, it's nonexistent. Only at acceleration and deceleration.
Any ideas and am I on the right track?

Spray the oil with carb cleaner and dab up what you can with a rag, the carb cleaner will evaporate the rest.

Better yet, go to your local car wash and power scrub the entire engine, bottom first then top with cold water only, you will have a very clean engine afterwards.
D2's, unlike D1's love water and there is nothing you can hurt under that hood.

My D2 with Magnecore 8mm wires and Bosch +4 plugs loves water so much, it produces catalyst-damaging misfires if I even spit on the engine. Be careful. I would recommend taking water to your engine only if you are in your driveway so that you can let it dry out before having to drive it. Been my experience anyway.

Aaron, if you have that sort of trouble, then you have some other issue cause D2 electrical system are water tight. What are the exact fault code numbers you are getting, no way can you get cat fault codes from water unless you have bad wire connections or cracked plugs.
