I just changed my spark plugs today (2 years) and found a couple of plugs in not so great condition. I was wondering if I may ask for some help in determing what's going on inside the cylinder?


These are plugs from the left side. #1 on bottom, #2 middle, #3 on top.



Now the right side is where i almost had a heart attack. #4 on bottom, #5 middle, #6 top. Four and five are covered in oil. Possible valve issues?


Finally I noticed plug #1 and it's corresponding wire had some sort of green corrosion on them. Could this be from water somehow entering the chamber during washing or rain splash while driving? I had to crush the plastic in order to remove it from the wire.
