this is a 4.6, but the 5.4 has the same problem.
i've seen the fix it kits but question them. of course, ford wants an
arm and a leg to do this job and what's the chances of another blow out
from happening down the road? also, is there a particular cylinger
that tends to blowout or is it at random?
just wonder what are some of the group's experiences with this kind of
is there any recall or service bulletins on this?

If the "sav-a-thread" bushing is PROPERLY installed, the repaired
cyl will never have a plug come out again. Ford should be installing
them at the factory - not sure why Ford - and the Triton in
particular, is having such a LARGE problem. Poor material? Poor heat
treating? or overheating?
I thought I had read that the Spark Plug blow-outs were problems on the
5.4L Triton, not the 4.6... Anyways, I too have not had any issues on
my 199 4.6L Triton, regarding blow-out. Have 118k miles on it. I
actually *did* have issues about 5K after replacing the plugs the first
time at about 90K miles. Started running rough, check engine light came
on, then started actually flashing. Talked to my bro-in-law mechanic
and told me to immediately go spend the $$ and get motorcraft plugs, and
take the autolites I had put in and throw them in the garbage, and that
the autolites specified do not get hot enough and are not right for the
engine, despite what any book at an auto-store tells you. When I really
looked at them you can see such a design difference between the plugs.
Autolites were thick and heavy, while the motorcrafts were thinner and
more delicate looking. You'd think that the autolites were a heavy duty
and better by looking at them, but alas - they were pieces of crap...at
least for my truck. One actually even felt like it had loosened up in
Anyway, put the motorcrafts in and the truck ran like new and havn't had
a problem since.
