Hey, I know there is a ton of information on here about the issue with the spark plugs in the triton motors throughout the years, but I was hoping someone could give me a paragraph synopsis of the whole issue. I was looking for a brief description of the problem, the years and engines typically affected, and what Ford has done to remedy the issue. Any other lingering issues surrounding this? Thanks
Actually the plug for the 3v engines was revised in 2008 and resembles a traditional spark plug. It has at least an inch of threads so there no chance of the plug popping out of the head. Below is a pic of the revised 2008 plug (top) and the previous 3v that are breaking apart on removal.
From what I've read, 5.4 3v engines with build dates (that's engine build date, not vehicle) after 10/8/07 got the new heads with revised plugs. The engine build date will be on the tag on the driver side valve cover.
If this happens to you and it will. Lisle tool company has the best kit I have found to remove the broken electrode. The part number is 65600 and it is worth its weight in gold. But is only around $100 bucks.
Good to know as I hope to get a lot of miles out of this truck. I just figured i'd change them before they seized, but that doesn't seem to problem. Anyone know if the plugs are different or just more threads on the head on the newer 4.6?
