If you have the room, you can do it. I am assuming an aluminum head. Buy a
helicoil, a special helicoil tap and the helicoil installation tool and go to
it. Downside? Yep, aluminum bits inside the combustion chamber-not good for
the rings, cylinder walls and exhaust valve. I would make sure that the
piston was at TDC for that cylinder so damage (if any) would be minimal. I
can't imagine that you blew a sparkplug out of a cast iron head.
An old trick back in pre-historic days was to use a larger diameter sparkplug
and just retap the sparkplug hole. I don't think you can do that today. But
are there larger diameter sparkplugs???

My daughter came home from school 400 miles away yesterday. This morning she
went
out to start her 89 ford Probe (similar to Mazda MX3), heard a bang and quit.
When I looked, it had blown a spark plug out of the head. Since he wants to
return Wednesday (and I don't want to give up my car until Xmas), we'll have
to
try to fix it.
Normally I'd yank the head, get an insert installed & a valve job while at
it.
Does anyone know if an insert can be installed with the head on the car? I'm
too
cheap to pay someone to remove & replace the head.
My apologies for bombing the list with a @#$%^**& Ford question, but thanks
in
advance.
