Do a search on "ford 5.4 spark plug blow out" & you will begin to get the pic, then there are threads here to add & are very helpful as well.. I just wish I had came here first or had read about it previously then I would have made the time to find out what was causing that noise sooner.. lol, it is what it is..

Hopefully this is not your issue with your truck, but dang sure is looking into before instead of after..
Also you mentioned the "previous owners stated they had recently changed the plugs"/
You believed this or did you check it out for yourself to verify they did?? Then did they do it or have it done at a dealer??
I would do some looking into this "before" it happens or becomes worst.
The check engine light has been off now for about a week, just randomly went off and drives fine, besides the noise. From what ive been reading, its the cam phrs. I was talkin to a mechanic about it, He had a 04 that his phayer noise was louder then mine.

Im pretty good friends with the last owners now, they told me ford changed the plugs.

But now i woke up with coolant all over the ground from the truck.... didn't want to do anything today, since its fathers day.. lol. oh well.

Thanks for the info!

Mine sounds like something fluttering at high rpms right before the tranny shifts.. I'm guessing it may be related to the fan belt.

Hopefully you found out what yours was!
