5.4 Triton (spark plug blown out of cyl head)

I have a 1999 E350 cube van that has blown a spark plug from the cyl head with apx 48,000 on it.

My question is, has anyone else had or know of any more concerns of this nature.

Thank you,

Terry McNeil

Several Lightnings(5.4L) have had plugs that blew out. Others have found the plugs little more than finger tight.

When you go to change them, remember to not over tighten them as there are only 4 or 5 threads to hold them in the aluminum head. On the Ls, you can't get a torque wrench(13 ft. lbs.) on several plugs so NGK says to tightne them "finger-tight" and then 1/16th of a turn more--careful!

I had this happen on my expedition with 38,000 miles on it. I was at idle when it broke a chunk off the head. Like to never got it to the dealer. They were pretty amazed, they had never seen it before.
