Default Blown sparkplug on Trition V8 (2002) 5.4L 350 XLT



This is BS. There is no recall, there is a TSB. If the plugs are
installed properly and torqued properly, there is no need to check
them every 5K miles. Ford did not use wrong torque spec - mechanics
replacing the plugs do. The proper torque spec is 11 ft.lbs. (14 Nm)
(or 9.5 to 20 Nm / 7 to 15 foot-pounds). As for whether or not it is
the wrong plug design, I guess it is if mechanics can't put them in
properly. I am confident than when the plugs are properly installed,
there won't be a problem. Unfortuntely, it appears it take a real
mechanic (skilled and careful) to do it correctly. Given the general
level of mechanics working these days, that means you are likely to
have a problem. This means it is a bad design. I owned two Expeditons
with the supposedly "bad" plugs, and in my family we had three other
vehicles with the supposedly bad design plugs. We never had a problem.
I had the plugs in my 1997 Expedition changed at 100,000 miles (they
actually looked good) and 50,000 miles later things were still fine. I
had the plugs in my 2003 (with supposedly different plugs - but they
looked the same) changed at 100,000 miles without incident. Mechanics
who don't torque the plugs properly can cause all sorts of problem. If
you don't torque them enough, they will loosen over time and destroy
the threads. If you use too high a torque, you destroy the threads
right away. I have seen it claimed that some engines came from Ford
with the plugs improperly torqued. I can't confirm this. I talked to
my local mechanics (not a Ford mechanic) and he's never seen one with
the problem unless someone had changed the plugs.

Ford just released a TSB that authorizes the use of a particualr type
of insert for non-warranty repairs (for warranty repairs, Ford says to
replace the head). Here is the TSB:

The BS is yours here. They did have a LOT of issue with plugs coming
out of 5.4 and V10 with aluminum head in years past and ford did
change the plug style and torque on them. You ned to get your ducks in
a row here before you spot off like this. Whiel Ford does not
recommand retightening them every 5K, I do on problem engine to make
sure they are staying snug. If they are not found loose after a few
times then you can skip it. It is/was a problem that Ford likes to
keep quiet about because they do not want to have to "eat" a lot of
them if they do not have too.

Snowblower! Have you ever thought about or even tried using a spell
checker? Your spelling is atrocious! Not as bad as most of you misguided
misinformation, but it does run a close second...

My 2002 F150 company work truck recently blew out the rear, passenger side
plug. Just under 40,000 miles on the truck. The plugs were original, never
removed or replaced. I have taken the truck in for all servicing, which up
to this incident has only been oil changes. It would have been nice to have
someone to blame for the problem, instead of Ford. It is kind of odd that
only Ford vehicles are having this "mechanic" caused problem. An improper
head design is the real culprit, or all aluminum head engines would have
similar, critical torque requirements and plug blow-outs.

Well.... I didn't mean to stir-up a hornets nest but I guess I did
inadvertently, AND got some good info to think about in the process. The
threads appear OK on the plug that blew out and I am checking to make sure
each of the plugs are tight (not too tight). Thanks again.

It takes a lot of effort to keep a bunch of ducks in line.
