Howdy-
A couple of tangential points: While discussing these plugs with someone
who's been doing this a lot longer than me, he made the observation that
these plugs do a better job of indicating the presence of moisture than
actually removing it. The more I thought about that, the more it made
sense to me. So, I used a couple gallons of Shell preservative oil and
thoroughly sloshed the engine, including the cylinders. When that was
done, I added another case of oil to the crankcase and stored the engine
upside down. (the engine was on it's mount, which was on a wooden firewall
mockup, which in turn was mounted to a Harbor Freight engine stand). All
the exhaust valve ports, the crankshaft, and the servo induction inlet were
capped. Well, that preservative is remarkable stuff. Given time, it will
make it's way out the tiniest opportunity, spread all over, drip the floor,
spread, and climb the nearest wall. Guess how I know.... I actually had
to have my FI servo disassembled and cleaned because this stuff had gotten
into it. So, my desiccator plugs filled with oil, even tho they were in
the upper plug holes as stored. This of course ruined them, but with the
oil spreading uphill, who needs them?
The weak link here seemed to be the valve ports. These I treated with an
aerosol engine preservative and capped. Two years later, the valve stems
are still shiny.
FWIW-

PS - I'll be out of town for the next 2-3 weeks

Listers,
I am updating my annual inspection checklist. I have a Lycoming O-320 with
Slick magnetos. Should these magnetos be pulled off the airplane every
annual for inspection of the points, gapping, etc or is it acceptable just
to check the timing. I know that the mags are due for an overhaul at 500
hours.
