Avoiding a Spark Plug Broken Off in Cylinder Head

Avoiding a Spark Plug Broken Off in Cylinder Head

(RockAuto.com is a MotorWeek Sponsor) Spark plugs can seize up in aluminum cylinder heads and cause big problems. This is especially true for the very long spark plugs used in Ford’s three…

thank you for the tip….I did my first set of plugs using your procedure
and remove 6 out of 8 with no problem. #3 and #5 broke and I used the
Lindsey extracting tools with no problems…best point # 4 and #8 came put
fine thank you Jesus and your video.

I won’t buy another ford, the shop wants $2000 to remove head to extract
plug out. YouTube videos have been a big help. Going in for myself with
spark plug tool removal kit. Then trade the bitch in. This is the second
time they get me.

maybe this is why i never have own a ford .

peskypeet says:

Don’t know if I’d use that type of anti seize, that’s the aluminum and
copper mix.
I think you want the Nickel stuff for this task.

Charles Mills says:

i have a mustang that has dart pro 1 heads,the car is rarely driven and
stays in a heated garage with a fan aiming at the car.do you think plugs
are more likely to stick in a aftermarket head.

WD Hewson says:

Where was Alan Mullaly when the Ford engineers made this pinnacle of
stupidity design?

Til Wow says:

Should be a sin to replace spark plugs that long.

A. Christian says:

“Normally I recommend that you leave spark plugs alone in an engine until
you have a problem”. Talk about bad advice! I always remove them and apply
anti-seize compound to the spark plug threads as soon as I buy a new car to
avoid having spark plug removal issues at a later date. I also remove them
every four years at the latest to reapply anti-seize compound and when
installing new spark plugs.

Or you warm the engine up and take the plugs out using an impact wrench.
They usually come right out this way.

i have this problem in my 4.0 

Tom says:

Never remove old spark plugs with the engine hot.

Robert Gift says:

Well done video! Thank you.
Scary procedure.
Great design, Ford idiotgineers. Make a two-piece spark plug that breaks
off in the cylinder head. Brilliant!

Good video hope I see it before breaking 3 of 8 sparkplugs on my 2005 F150
v3 5.4

codyq0987 says:

great video! May you tell me the specific grease you use for the boot?
Thank you

Nick T says:

I wish pat goss would replace the plugs on my 03 f250 super duty 5.4 

Adam Alvarez says:

He’s applying it to the part of the plug that does not have threads, which
doesn’t affect torquing because on a new plug there is no carbon, so little
or no friction on that area. He’s not applying it to the threads.

Thomas Kimble says:

Good info

bgregg55 says:

The problem with using anti-seize goop is that it’s very easy to overtorque
during install as the goop reduces the coefficient of friction
dramatically. I thought all plugs came pre-coated now.

danwat1234 says:

Yea I thought all “good” spark plugs (NGK) at least come pre-coated now on
the threads but he is applying anti-seize to part of the body of the plug

narox says:

Ford screwed up on this design.
