'10 Expy Spark Plugs, Still a Problem?

Just wondering if the 2010s have the same spark plug removal issues as the earlier models. If so I'd like to know so I can pull them now and reinstall with some anti-sieze. Any thoughts?

Thanks!

no

In 2007 Ford revised the heads/plugs to a traditional 1 piece plug


all 2008+ 4.6 3v and 5.4 3v motors are now fixed

Thanks Tylus... that's good to know. Having read all of the posts regarding that issue I was hoping Ford had actually done something to correct it. I also have a '04 Expedition with the 2v 5.4. Haven't attempted to change the plugs on it but feel it's time with 85K on the odometer. Do the two valve engines have the same issue?

Thanks again for the help!

We all knew about the blowout problem on the 2 valve 5.4's,I thought that problem was fixed when the 3 valve 5.4 came out with MORE threads per plug BUT that MADE a problem trying to change the plugs and having them break off,something about the threads being below the bottom of the head and carbon/soot building up on the bottom of the plugs causing them to bind up in the head on the way out,what's the story now?????.

here is the lowdown on the spark plugs from about 2000 to current

2000-2003
4.6 2v
5.4 2v
V-10

problem seemed to surface when Ford started using the PI heads. spark plugs ejected from the head due to insufficient threads in the head. repairs required either a heli-coil or insert...or a new head.

it's completely random and can happen to anyone. Some people never have it happen...and some poor *******s have it happen one after another

2004-2007(midyear)

4.6 3v
5.4 3v

spark plugs are a multiple piece design that is tack welded together. Ford also increased the threads inside the head to fix the blow-out issue...the nature of the 3v head made for an extremely small space where the plug penetrates the cylinder

carbon from the ignition process and unburnt fuel collects around the spark plug. this causes the spark plug to get caught. the tack weld breaks and the plug will come out in 2-3 pieces.

doesn't always happen...but it's a definite possibility

2008-current
4.6 3v
5.4 3v

in late 2007 Ford issued a redesigned head that went back to a traditional sparkplug.

motors built after Nov 2007 have the new design head. So if you are looking at a 2008 model Ford, you need to look at the drivers side head. it will have a build date sticker on there. You want one built after the revision was issued.

Thanks tylus... that's good info. It looks like I'm okay with the '10, not so much with the '04.

What about the v10-2008? You don't mention the v10....

the 2v V-10 has been known to eject plugs (1999-2004 motors)

and

the 3v V-10 has been known to have plugs stick in the head (2005+ motors)


basically, the V-10 heads are identical to the 4.6/5.4 heads...just 2 extra cylinders. So all the fun stuff they suffered from, the V-10 got to have as well.



fun fact: the 4.6 2v and 3v heads are the exact same heads that are on the 5.4 2v and 3v
