while this problem isn't happening on a hyundai, it concievably could......

I just picked up a backup car, a 93 olds achieva with a dohc 4 cyl.

found out from service records that one spark plug is cross threaded. what
options does one have when this plug stops working? will the head need to
be pulled, or is there an easier solution?

hopefully no one is too offended by my non-hyundai question, but I've been
on this NG for about a year, and I kinda like talking to you people!!

thanks for any and all help.

It really is a question you should take to alt.autos.gm. Of course we're
all nice guys here, but there really is a newsgroup for this question.

You won't know what's necessary until you get the old plug out. Many GM
techs use anti-seize on plugs to keep the threads from being damaged when
replacing plugs.

If it's not too bad, some anti-seize and a new plug may work fine.
Always
replace plugs on a GM engine when cold. Probably due to thermal
expansion,
most thread problems occur when servicing plugs on a warm engine. Or you
may be able to clean up the threads with a tap. Worst case, you'd need
to
install a helicoil. But tapping or drilling for the helicoil will
introduce shavings into the combustion chamber. They'll probably blow
out
with no damage, but the possibility of worse is always there.

That's where a vac with a narrow nozzle comes in handy.
