Gary; another question, just looking at the twin hoses running aft from the port
side valve cover. The typical oil separator setup has a fitting coming off
the top of the valve cover, going to the separator, then returning oil to the
valve cover. I take it that's where those hoses are leading to, is an oil separator
on the firewall? So, how does your setup work? Is there a breather tube
exiting the bottom of the cowling from the separator?

a couple inches of pitch or length really changes the thrust
of course there are more variables but interesting

Oscar,
How timely!!! My system is set to exit the top hose, enter a Cessna style
air/oil separator, return via the bottom hose, with an overflow that is
routed under the firewall. Today, a local stopped by and asked the same
question, "How well does that work?" His concern is that, in a left steep
turn or turns about a point, the breathing system may get overwhelmed with
oil. A few months ago, in left turns about my house, the engine sputtered
and emitted smoke from the left side. I assumed that I had picked up some
condensation or water. The local wants me to change it so that the 'Outlet'
from the separator is routed back to the top cover of the engine, not the
valve cover. I have yet to converse with WW about that.
Your thoughts?

Gary;
I would not say that William Wynne has the ONLY solution to proper crankcase venting,
but he certainly has one that works. Before you do anything with the top
cover, do talk with William. Meanwhile, here's a snip from one of his posts
after Corvair College 20, which was in 2011:
"The engine fired right up on the test stand and ran very well, however it began
to leak a little oil after a few minutes. Normally this does not bother me.
The focus of the test run is to break in the camshaft lifters. If the engine leaks
oil, I usually let it go if it is not severe. I carefully studied Bills engine
as it ran on the stand, and I noticed it was showing oil leaking from several
of the pushrod tubes at once. There is an easy explanation for an engine
leaking oil from a lot of different places unexpectedly: The breather is not
working. Because Bill is installing his engine on a Pietenpol, he was a little
reluctant to have the oil filler and breathers in the valve covers. He incorporated
a breather into the top cover on his engine. And packed it with a Scotch
Brite-like material to act as a filtration device. The net effect was to restrict
the outflow of crankcase vapors excessively. When the crankcase becomes
pressurized with blow by air, it does not take more than three or four pounds
of pressure to make the engine leak oil from numerous places. If you're considering
a unique oil breather arrangement, understand that I've tried almost every
location on the engine, and numerous different designs. Having the oil filler
neck and breathers in the valve covers was not my first choice; it evolved
over years of testing. With a corrected crankcase venting system, Bills engine
will show itself to be an outstanding powerplant and probably remain leak free."

The infraction here appears to be the packing material...not sure why someone would
do that. Stock Corvairs have the vent return into the top cover. Thanks for
digging that up, Oscar! I know WW is busy right now, and I'm not desperate
for an answer. Steep turns and turns about a point will be made to the right!

WW's latest manual still incorporates two welded lines into the left cover, as
I did, and I used the ACS #10570 separator as he suggests.

Paul,
This all happened quite by accident, but I am well-experienced in making
chicken pie out of chicken s__t...
Long story, but my heads were returned to me with volkswagon style exhaust
ports. You can see that each one has welded to it a two-hole bracket, which
correspondingly bolts to a two-hole bracket on the exhaust tubes. WW offered
to weld for me a joined up system of exhaust tubes, one for each side,
somewhat similar to the exhaust logs typical for a Corvair. Instead, I opted
for the individual exhausts, easily fabricated from 'U-bends' from
www.magnumforce.com. When these wear out, I'll replace with stainless.

sure I understand how you fabricated them, but was hoping you could describe
the setup and maybe some pics too. Woild love to go without the logs.

Subject: Pietenpol-List: dawn patrol
Today I slipped another dawn patrol in. Got to the airport about
nine, temp was around 40, but the winds were perfect (calm) so I suited
up. Did five take offs and landings and only landed high once, but no
biggie; just tap the throttle, keep the stick back, keep her straight
and she tracks true.
Proceeded to patrol the lines but no Huns showed their faces, all
clear. Patrolled over the house, waved to the wife and proceed to wake
up my friend at his house a few miles up the road before returning to
base. Good landing. She runs rich because. it's a continental and the
long pipes make it run even richer AND my engine guy doesn't want me to
lean her out until 25 hours, so I've invested in rags and cleaner
because with those really cool long pipes.. The stuff gets all over the
fuselage and tail. Yuck!! Oh well..Coolness trumps practicality
sometimes!!!!!
Nice still day so I think I got some good gps readings.
Cruise at 2200 is around 70.
2400 seems to produce around 75.
2000 is 65ish, maybe a bit less.
2000 to 2200 is FUN. the engine just purrs along sipping the gas, she
trims out nicely and just chugs along very quietly.
It was cold so she climbed REALLY well, my gps vertical climb
indicator was reading between 600 and 750fpm on a totally normal
climb-out, so I decided to actually try a steep(ish) climb and got a
steady 1,000. I believe the gps is accurate, but attribute those high
numbers to the cold, the big C-90/cloudcar prop combo up front, combined
with little fuel and me only weighing 160 all clothed up.
Keep building, it's worth it!

While organizing Piet photos I found this one Marci shot one night. Thought
it captured something nice about the building process that some would
appreciate, hence the forward.
Changed out my old original starter which had a clutch going bad for a new
lightweight Skytech. Saved SIX pounds!!
Easiest weight saving I ever heard of (except for the purchase price...)

The photo captures a couple of things that I can see: (1) mounting anticipation
as the building part nears an end and the flying part is close enough to feel;
(2) as the building part nears its end and you enjoy it more and more, it's
getting to be less and less; (3) this is why we build Air Campers and not Glasairs
or RVs.
No offense meant against those other designs, but this airplane spans so much aviation
history that we can almost grab it all with this one time machine.

| Subject: | What you can accomplish if you just spend some time building |
I know I am not alone in the "start again, stop again" building process, but I
have been surprised by how quickly I have progressed recently. I stopped for almost
the entire last half of 2012 because of a video project I was producing
and, since I worked at home, I felt every moment I was in the shop was time I
should have spent editing and finishing the video.
But, I bought the steel for the control stick, elevator bar, rudder bar and pedals,
and related assemblies, but ran out of money before I got the welding set
up. When I finally had time, I had run outta money to buy the tanks and welding
equipment.
A friend had a set of tanks and all the torches I needed to start welding, and
needed a place to store them after breaking up with his girlfriend, so 3 weekends
ago he dropped them off and I started putting metal together.
I was skeptical about whether I could weld well enough to produce a safe airplane,
but I had some good encouragement from Gary Booth when he came to visit and
he was right: it ain't THAT hard to do a good weld joint. Where I once felt
I would have a professional do my LG and Engine mount, I now think I can do just
fine. Thanks Gary!
So, I told my wife that I thought it would take me 2-3 months to get to the point
of finishing the steel parts I had bought. It has taken about 3 weeks to build
everything. Well, I still have the front rudder pedals to do, but all the
rest is finished and ready for the zinc paint. I thing the time to varnish the
inside has come, then paint the metal bits and plug them in! Progress!
Here's some pics of Jody sitting in her perch as I measured out where to put the
pedals for her short statured legs. I made her stick removable so I could use
the front seat as storage if she isn't flying.
Now, what's next...
