I removed my spark plug wires, and upon removing them, it seems oil has been in some of my spark plug holes. #3 is the worst, #2 & #4 are a little bad, and #1 and #5 are pretty clean. Also my wires have discoloration in accordance with the most oil. I never noticed this before when i changed my plugs at nite, but is it normal?
Any help would be appreciated. Thanks!
