Hi all, I was hoping to get folk's thoughts on whether these plugs look acceptable for 55k of use, and more specifically about what would cause oil to get onto the plug from the #5 cylinder. These plugs came out of a 5.4 3V Ford with 164k miles.
Not all of the plugs are pictured, as one had been changed about a month ago and I have two still left to change.
