Yup, it never ends... After a week of cleaning the port engine, flying
it, inspecting for leaks, cleaning it again, tightening even more
fittings, flying it, and finally discovering that the mounting nuts on
the prop governor were barely more than finger tight, I had the leak(s)
stopped... Flew it more than an hour (cool day)... Pulled the side
cowls for inspection... Engine dry as a bone... Yippee skip..
I decided to do the oil change as I had 26 hours on the tachs since
last oil change and the fall temps are coming so it's time to bid adieu
to the 100W and fill with 15W50... FIlters were past 50 hours and due
also... So my son and I went into the oil change drill (his first time
on an airplane, though he is a competent mechanic)... 16 quarts of
oil, 2 cans of AVBLEND, and two filters later, he discovered that
changing the horizontal filters on an O-320 is a messy job... So, back
out to the wash down lawn where we again used citrus cleaner, rags,
and a garden sprayer to get the engines and cowlings squeaky clean...
Test run showed no leaks, so back on with the side cowls.. (gee, it
even smells good)
We went out for some 'circuits and bangs', as the English put it...
Dennis has a few hours of stick time in the air and attempted only two
landings before this, so it was exciting... He is starting ab initio
in a twin, with carbs and heat boxes, hydraulic gear and flaps,
constant speed props, etc., which is even more exciting... The air
temperature was above 80 and the engines got warm... After landing I'm
just crawling out when Dennis says, "Oil dripping... Big time!"...
jeez
We pulled the side cowls and the rear of the port engine is drenched,
though the oil filter (my initial thought) is clean and dry... At this
point we suspect the oil temperature bulb is leaking when it gets hot,
but it is up under the top cowling and invisible until the cowl is
removed... At that point we had been at it for some 7 hours and we
were whipped... So, I will get out there Wednesday afternoon and pull
the top cowling and try to verify it as being the temperature sender...
