spark plugs and triton engines
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

The mod motor likes to eject spark plugs due to an insufficient # of spark plug threads
the 5.4 mod motor has very narrow passages surrounding the plugs inside the cylinder...this allows crap to accululate on the electrode and causes the spark plug to occasionally break
the 4.6 3v and the 6.8 have been fixed so they no longer eject spark plugs
1992-2004 4.6 2v in the cars/suvs
1997-2004 4.6 2v in F-150 (2004 in old body style trucks only, not new body style truck)
1997-2003 5.4 2v
1997-2003 6.8
1997-2004 4.6 2v in F-150 (2004 in old body style trucks only, not new body style truck)
1997-2003 5.4 2v
1997-2003 6.8

2004-2008 5.4 3v in F-150/Mark LT/Superduty/Econoline/Navigator/Expedition
the 4.6 3v and the 6.8 have been fixed so they no longer eject spark plugs

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.

At 32k is early for a plug change plus the early 4.6-2v's would blow the plugs out. I think that problem was corrected by '08
