Yikes, sorry about that one. Meant heads not block. What the hell was I thinking?
I know the V8 and V10 are from the same family, but there are some major differences in them. Like I said, to my knowledge, the V8s didn't have that issue. The 5.4 in my Expo went over 200k miles and never did it. The 5.4 in my father's truck did the same. The 4.6 in my sister's truck did as well. It also seems that the v8 in the OP's Expo has almost done the same as well. I could be wrong though, but I would still never use an impact to change spark plugs.
Sorry again for the confusion.
I have helped repair many V8's with this problem. It is so common there is a kit to fix it, probably worth buying one and keeping it around. I gave the one I had to a buddy in Wy who had blown 2 out of his 5.4 at last count. I have never owned a ford with one these motors, but I still had a kit to fix it (for friends) if that tells you anything. I have also never touched a V10 ford.
