Hi,
I had to remove broken spark plugs in the past. On my dad's jaguar
v12 the ceramic on the spark plug broke off. If the nut part of the plug
is still in use a 6 point wrench to get it out. Another way is to heat
up the plug with a torch. Your block must be steel. If it's aluminum
you'll melt it. A Propane or Butane torch will work. You'll have to heat
it up quite a bit. It won't melt or discolor as the torch won't get hot
enough. You can also cut it out with a oxy/acetylene torch with a small
cutting torch tip or a small scarfing tip. You will be skimming the
inside of the plug with the torch. The plug will heat up just fine
without doing harm to the block threads. The plug will retain the heat
and the block will stay cool as it is much larger and will dissipate the
heat well. You can also drive a good chisel through the ceramic and make
a hole in it. The ceramic is hard so it will take effort. Once this is
done you'll be able to "Easy Out" the remainder of the plug. Heating it
up though with a Propane or Butane torch and using a 6 point wrench is
probably your best bet. Be sure to use compressed air and goggles to
blow out the cylinder of Debris when your done. Make definitely sure
that the cylinder is clean. There is an industrial type of anti seize
which is gray and brush on. You should be able to pick it up at an Ace
hardware, home depot, or plumbing place. I use it on my Porsche 911 nuts
and bolts. It works great. Heat will be your best bet. Penetrating oil
is not my choice. Whenever I replace badly rusted brake lines I always's
use a torch to heat them. It works great for loosening rust. Also, be
carful using an open flame by the carb, fuel lines, wiring harness, or
battery. I've had a couple of batteries blow up on me from an open
flame. It's like a grenade. I was deaf for a while as well as the acid
burns on my face and chest. Luckily, I healed just fine. Good luck to
you and if I can help drop me a line.
