3-valve 5.4 plug change???
 

Just curious to see if anyone on here has done a spark plug replacement on one of these beast... I am about to tackle mine in the truck was just looking for some local advice. I have read tons of stuff on different forums just thought i would ask around on here... thanks in advance....

From what i have heard run seafoam through it and let it set for an hour or so before removing plugs.

Seafoam will help but be prepared to extract some broken plugs. Go ahead and buy the broke plug removal tool, especially if you have over 100k miles.

Do yourself a favor and pony up for the one piece plugs (champion) they are about $19 a piece.

Yeah broken plugs SUCK . I had it happen a couple of years ago when installing an Edelbrock Supercharger on a co-workers Stang :banghead:

youtube search....look for the guy who does it with an impact wrench...no kidding..I'll see if I can find it, says that's how he does it ALL THE TIME and has never had one break...

don't mind the "herbert" voice...lol https://encrypted-tbn3.google.com/im...iCQjItgj1XtwK0

dude shows you how to make this about a 15 min change start to finish...

only takes him like 4 mins to take all of them OUT!!! He takes EVERY ONE OF THEM out with the impact wrench...and the truck has 120K on the odometer

I can't agree with this, my opinion is it's BS. The two piece design of the plugs plus carbon build up is what breaks them and it doesn't take much.

Like I said....my opinion

you watch the video? I wouldn't have believed it either cause I've had friends with Harley trucks and those are a PITA to change plugs on...just watch the video, obviously this guys done a $H!T TON of these since he's most likely a FORD tech...but still.....those guys get book value for jobs, they are going to find the EASIEST way to do something...
