I was planning on changing spark plugs and wires tonight on the 97 accord and realized that there is a buildup of oil when I removed the third spark plug wire. I have never seen this before. Is this due to the valve cover gasket seal being worn and as a result it lets oil on the top part of the spark plug? Cause when I removed the rubber piece that seats onto the spark plug it seems that it was sitting in a pool of oil.. However there is no misfiring and the car runs fine, but I do want to get down to the bottom of this problem,,, please help! Thx
