Good idea about the injector harness Tony: That way I can get it to a garage.
I've been trying an extractor, but afraid to snap it off with everything so
cold.
Cheers,
Mark

Subject: [TR] Fw: Sparked out
I assume the electrode was attached to the now departed body of the plug ...
if so, the good news is that you are left with a pilot hole that will help
center any easy out or drill that you use.
I am not sure that any easy out will do much good, and it may end up doing
more harm. The fact the threaded section has seized to the point where it
sheared does sorta tell you that it is well and truly stuck! If the head
it
an alloy head, and you can get a lot of heat to the offending plug without
incinerating anything else important, you "might" find an easy out will
work.
My son has a similar problem with an alloy head, caused by what looked like
long term corrosion (and probably some dielectric effect as well). We
drilled out the most of the body with a 9/16" drill. Once drilled, it was
possible to "extract" what was left from the threaded section. I am
guessing the heating, vibration and plain good fortune smiling on us,
allowed the threaded bit to be levered out using picks and needle nose
pliers. If that hadn't have worked, we did have the tapping drill (21/32")
and the 14x1.25 tap, so we would have drilled and tapped the thread once
more.
Once this part is over, you will need to be able to put a pneumatic blow
gun
through the spark plug hole and blow the debris and crap out. Really take
you time on this stage .... once thoroughly blown, I removed all the plugs
and pulled of the igniter pack feed and turned the engine over on the
starter for a good while too. Once it has started and run up to temp. I
suggest changing the oil as well.
If all this is too much, just pull the harness connector off the injector
for this cylinder (it will be on the fuel rail that runs along the side of
the valley). That will stop that injector admitting fuel to the cylinder
and diluting your oil, etc., and live with the chuffing and puffing until
things get warm!
Good luck,
