Yup. Before they had that problem, the Triton had spark plugs blowing out of the holes. I've got an 03 V-10, had to put new replacement heads on it. Only three threads in that aluminum head holding the spark plug... so then they loosen up and tear the threads out of the hole on the way out. Like a shotgun going off under the hood when they come out. I put "inserts" in first, but they didn't hold either. And the Ford engineers had the bright idea of making it so you have to pull the motor out the grill, or pull the body off the truck to change the heads. Brilliant! Nice motor though, once I got new heads put on. I guess the broken off spark plugs are more costly to fix than the "blow 'em out of the hole" problem, from what I've heard.I don't know if that model was the one that liked to break off spark plugs in the head, but I'd suggest changing them sooner rather than later so they're hopefully not seized in
