Obviously you didn't. I conveyed what I have learned, and that is crankcase
evacuation has has many benefits. I am not the first to have proven that
drawing a vacuum on the crankcase has many benefits. The original poster
asked if it was advisable to plumb the crankcase vent into the exhaust. My
experience through my own experiments with crankcase venting have proven
that yes indeed positively venting the crankcase is a good idea.

Let me repost my comments here so you can read them since apparently you
never did in the first place:
I have a wet vacuum pump pulling set to pull 9" Hg. vacuum on my crankcase
thru the breather vent and it works great. My oil consumption went from 1
qt. every 5-7 hours to 1 qt. every 20-25 hours. I have the oil analysis to
prove that the cam isn't making any metal due to lack of oil splash and I
believe the engine runs smoother, idles lower, and seems to be making some
more power but I have no scientific proof of it. I have a flapper door
check valve designed into the system so if the vacuum pump quits the
breather will vent to ambient. I have about 50 hours on this setup now and
it works fine so far. I was advised by two different engine builders who
have this setup flying on Reno race aircraft to install a new crank seal
backwards to so that the vacuum doesn't draw air in thru the front of the
engine and that too has been trouble-free.
Based on my experience with the above I highly encourage anyone willing to
experiment with pulling a vacuum on the crankcase through the exhaust.
There are many aerobatic aircraft flying that are configured this way and
work just fine.
Particularly pay attention to the last sentence of the first paragraph since
you keep bringing it up. You called me a liar since you had no idea how to
respond to something that perhaps your vast education and experience did not
prepare you for. Obviously the acquisition of people skills were not a part
of any of that. I get a chuckle out of your responses, because I have no
motivation to lie or misrepresent. I will gladly take pictures of the setup
at the next oil change due in in a week after I make a 800nm trip in my RV-6
(not a 6A as you incorrectly referred to in your previous rambling
diatribe).
The exact same system is installed on a IO-540 on Mark Frederick's #84 F1
Rocket which raced at reno several times. I will repeat it so you can
hopefully understand, Mark Frederick raced with this setup several times at
Reno. It is simply a wet vacuum pump plumbed into the breather with the
outlet going to an air/oil separator. The engine builder who built his 540
claimed a 14hp increase on the dyno from this mod alone and a 1hp penalty to
turn the vacuum pump. Once the crankcase is evacuated there is very little
hp loss from turning the pump. It works just the same as sticking one's
hand on the end of a vacuum cleaner hose; the vacuum motor will speed up
because there is less resistance to the motor without any air to pump. Doug
Rozendaal now owns the airplane and I suspect the vacuum evacuation system
is still installed. You have claimed in the past you are friends with Mark
and have hung out in his booth at OSH. I find it funny that he has no idea
who you are. And if you hung around the booth as you have stated in the
past you would have seen this system since his airplane is always un-cowled
for the world to see. I guess the fact that he had this same system but
didn't document it for your review makes him liar too.
All I heard was sarcastic "straw-man" arguments and points

Again, please do thoroughly read what people post, it will make you look

Your education/experience is just about as relevant to the subject at hand
as the experience a doctor may have applies towards changing the oil in my
car. It means nothing. You choose not to reveal yourself and that throws
any credibility you may have right down the crapper. I have a bachelor's
degree and am a successful software engineer, but that has absolutely no
relevance to this discussion. You seem to be the only one I've ever seen on
the various RV forums that flaunts your supposed educational and
professional background, like it makes you any more of an expert at building
an airplane than people of other professions do.

Factual disagreement is welcome. Disrespect isn't.
PCV evacuation systems have been used on ALL automobiles in this country
since the mid 60's, and the system I have experimented with a different
variation to the same idea. The reason why you'd install a PCV valve where
the crankcase vent hose meets the exhaust is to prevent the flow of exhaust
into the crankcase, such as at low rpm when crankcase pressures are low. I
have my crankcase instrumented with a manifold pressure gauge and I know
what it does at various power settings. You can disagree if you like. I
suppose you can argue the world is still flat while you're at it.

I don't recall anyone in this thread asking for advice on how complex they
should build their airplane. The original poster asked if it was ok to
plumb the breather into the exhaust. Other than the addition of a PCV
valve, it is not complicated to do at all and adds very little in complexity
to the breather over an existing setup. I have an AutoCAD drawing that was
sent to me a few years ago by a fellow lister that showed how to weld a bung
on the exhaust at a 45 degree angle and which PCV valve to use. Like I said
its been done before, and nobody has fallen out of the sky as a result of
that kind of modification.

Obviously you have forgotten that you have spewed vulgarities to others here
on this list, called others names, and mocked others with phallic
misrepresentations of their last names, amongst other things. That's what
is truly shameful. Some things you have said are quite childish and it
leads me to suspect that your claims of education and/or background are
false, because the sort of behavior you've engaged in is not representative
of a normal adult let alone someone who thinks their occupation makes them
an expert on things they are obviously not an expert on.

One more thing, you make a salient point about how a turbo-charged engine
makes more blow-by. What do you think happens when there is less than
ambient crankcase pressure? Even more blowby? Man those facts sometimes
indeed can really get in the way of making a valid argument. Long ago when
I worked on turbocharged airplanes while I was in college, I learned that
the crankcase indeed does get pressurized and that is why a gear-driven
Romec fuel pump is typically used. It is because crankcase pressures will
an effect on diaphragm pumps since they are vented to the crankcase, but a
gear driven pump dispenses with that problem. Crankcase pressurization is
the reason why fuel components are referenced to the upper deck on a turbo
engine.

I disagree. I think Evan said it the way he wanted to. Diplomacy (and
being politically correct) only go so far. He was off somewhere else
and returned to find out there's a problem. He was miffed, and I
understand why.
However, this points to a rather common problem. When a one-man shop
escapes for some quality time, and folks can't reach him/her they
panic. For whatever reason. I've been in the situation where my
supplier went TU (thank you for the education Mr. Bede) and like a lot
of y'all out there in the same spot, it wasn't a pleasant experience.
Some folks have an autoresponder that replies to emails when they're out
of the office. I don't know how to do that, or if I can. That would
work. Or a message on an answering machine. I'm not happy with telling
someone that I'm not home and won't be for 2 weeks. I'd really be
ticked to return to an empty house/shop ... and I mean really empty
...... so maybe that's not a solution. What say y'all ..... maybe we
need a spot on someones site that vendors can post info. I don't know.
I do know that when I played consultant, and I was busy or on vacation
.... or just plain hibernating .... I didn't answer the phone, check
messages, or make any contact with the rest of the world. That's what
escapism is all about. John might still get his tanks on time for OSH,
so the rest of us should send good vibes.

For the record, the original poster did not mention the supplier, nor even the

just requested ideas on what he should do.
Being in business is hard; really hard. I don't think there's anything more difficult
than running your own business.
That said, a lot comes with the territory. C'est la vie.

I think the more common problem is that people panic when they have no
reason to. In this case, the customer ordered in February, and said he
didn't need the parts until just before Oshkosh. The vendor probably
scheduled the work with that timeframe in mind. Yet the customer's post
accented that it had taken *months* to get his parts delivered. If he
wanted or expected them sooner, he should have said so.
I think this one-man-shop excercised extreme restraint in his post to this
list. I applaud him for posting his side of the story in blunt yet polite
terms. His credibility has been fully restored as far as i'm concerned.

Evans credibility was never in question. Johns post never came across as
convicting him in the first place but rather a question of how to deal with
it. Since John was not able to contact him and the time was getting very
short, I would have been concerned also. If I am going to receive something
at the last minute, I would be calling. If I couldn't reach them I might
have been close to panic also. It really just sounds like a
miss-communication. No big deal.

The years are finally catching up on my good friend Don Farand, who is now offering
his VFR/Night RV8 for $60k. This is the third RV that Don built. It is in
good shape, always hangared and is a solid flyer but the paint is a bit rough.
The bargain price can fix the cosmetics. Total time is 240 hours on both the
airframe and Lycoming O360 A1A (new from Vans). It has a 3-blade Catto , an Apollo
SL60 Com/GPS/Intercom, Narco AT150 transponder, KS Avionics, Tetra II, EGT/CHT
monitor, Vans steam gauges, and a Lowrance Airmap backup GPS. It also has
Oregon Aero seats, 5-point harnesses and includes a Telex ANR4000 headset.
The plane is currently located in Lincoln, near Sacramento, California. For more
information or a look/see call Don at 916-543-2889 or write him at dotndon1950@sbcglobal.net.

Dearest Gentlemen, and the person we know simply as "George",
I recommend that we leave this subject line alone, as everyone knows by
now where everyone else stands, and the exact opinion they represent...
May they be "Right or Wrong"?
I think we have beaten this horse not only around the corner quite a
bit, but also -to death- a couple of times over... So may this one now
hopefully get the final R. I. P. for good!
Time to move on to more pleasant and more productive discussions,
hopefully with more civility and respect toward each other, incl.
accepting each others opinions just as that.
Sincerely,
Konrad L. Werner

And in the end what did we learn?
Nothing,
because not one of our heroes has dared showed us how they
did their super secret crankcase evacuation system with the
exhaust or wet vacuum pump. May be its gerbils next?
They say IT'S GREAT! but then can tell us why or show us how.
Hummmm? Did they even try it?
All I heard was sarcastic "straw-man" arguments and points
made by saying, "Reno Racer" & "turbo-charger". What?
The rest of the comments where about me or attacking me for
various reasons? I guess I offended people because I went to
engineering school and fly planes? Why would that be
relevant? Sorry I went to school and fly planes for a living. Oh
yea I don't think PCV is necessary or value added, and that
really set the tribe off into a Tizzy. I dared disagree; how could I.
Attn: Guys who just want to build your RV, the quickest way
to finish and fly a nice RV, that is safe, reliable, light and fun is
to follow the plans in my opinion. You can quote me. Leave off
the exhaust sucker or wet vacuum pump for now. If you want
to use it later, research it, call Lyc, Van and yes call a "Reno
Racer" and ask them directly. BTW: super-charged or turbo-
charged engines have more blow-by into the crank case than a
normally aspirated engines like ours. (facts again darn it)
Part of the fun is learning, and I am truly sorry that may be all
you learned is there's a "gang" on the list who makes personal
attacks to "put people into their place", so you might be
intimidated from asking a question. That's a shame. If you need
help email me direct; I'll help if I can and won't make fun of you
even if you are a pilot or went to school.
I am happy however if you learned to be careful and check it
out for your self, not to unilaterally believe me or the experts.
It is a good lesson, check it out and learn, your life or your wife
or kids life may depend on it. Be careful with engine mods.
Building is learning and is fun; ignore the dolts.
Asbestos underwear on so flame away. Nuff said

The paint area of a RV-6A is as follows.
Take the area and use the manufacture's recommended coverage for
primer (please forgive the use of that "word") and finish coats and
volia, you have the amount required, Do not forget to add in the
amount that does not actually end up on the plane.

Bob, I would like to see the pictures if you take them. I am curious about this.
"Bob J." I will gladly take pictures of the setup at the next oil change due in
in a week after I make a 800nm trip in my RV-6
