Thanks for all of the ideas. I will continue to soak the plug and see
if we can break her free.
Regards,
Don

Aircraft plug manufacturers recommend using
a light anti seize compound on the threads, avoiding
getting any on the "nose" of the plug.
Most have their own, which is a bit thinner than
the more conventional anti-seize.

Tedd,
It is more important to use anti-seize on air cooled aircraft engines
because the aluminum head and therefore the threaded head-to-plug joint runs
much hotter than with liquid cooled engines.
I not seen any evidence that anti-seize affects plug temperature; it might
even reduce it by increasing thread contact area with the head. In any
event, I believe that any such change is negligible relative to other
factors.
I use anti-seize on all spark plugs used with aluminum heads (both air and
liquid cooled), either the usual paste type or plain graphite powder. I
suggest that the very long plug maintenance intervals with modern cars and
poor access with most V engines (to the plugs for 'rear' cylinders) makes
anti-seize increasingly important.

On automotive engines I have always used Copaslip or a similar,
high-temperature anti-sieze compound on the spark plug threads. But many
years
ago someone told that that this is a bad idea on engines with air cooled
cylinder heads, due to lowering the heat transfer between the plug and the
head. I've always thought this advice had "old wives tale" written all over
it, but it has nevertheless prevented me from using anti-sieze compound on
aircraft engines. Am I worried about nothing?

Don't bother, just add heat. I noticed you live in B.C.; Add more heat than
usual.

On automotive engines I have always used Copaslip or a similar, high-temperature
anti-sieze compound on the spark plug threads. But many years ago someone told
that that this is a bad idea on engines with air cooled cylinder heads, due to
lowering the heat transfer between the plug and the head. I've always thought
this advice had "old wives tale" written all over it, but it has nevertheless
prevented me from using anti-sieze compound on aircraft engines. Am I worried
about nothing?

On our club aircraft, we do 50 hour inspections and
oil changes. Every inspection includes spark plug
cleaning and regapping. Before the plugs are
re-installed, a very small amount of Champion Spark
Plug Lubricant is applied to the threads. I must
emphasize, a very small amount is used. Over a period
of 2000 hours, that amounts 40 times the spark plugs
are removed and re-installed.

I use the Permatex 'silver' anti-seize compound. I've never had any
problems with it.

I did have a plug stick in a cylinder head on an O540 in a Commanche. When
the plug came out, the heli-coil came with it. THe owner claimed he always
used the Champion anti-seize. I've always used the Permatex anti-seize and
I've been very happy with it.
