Thanks for reply..............I am using the 7 tube cooler Van's sells and
it is mounted on the left rear baffle. This is what Van's suggests for a 0-
360. Surely I am not the only guy with this "challenge?'
My CHT's are about 325=C2=B0F.........

You may consider building an exit ramp inside the cowling that looks like a
fairing around the whole nosegear cluster. This should smooth the hot exit
airflow quite a bit...
How are you CHT's doing when the oil is at 220 degrees? Perhaps you just n

I'm flying a RV-6A I built a few years ago and have always had oil temps ab
out 220=C2=B0F on 90=C2=B0 days..
I am wondering what the difference is between the RV-6 and 6A that causes m
any 6A's to have elevated oil temps. Besides the nose wheel structure in t
he cowling air exit that is. If you have a tri gear and experience the sam
e malady, do you have the intersection fairing between the nose wheel strut
and the lower cowl?? I do not as of now. My baffles are sealed about as w
ell as I can get them also. That is a high pressure area during flight an
d I wonder if enough air is leaking into the cowl to raise the pressure in
the lower section, i.e. less flow. If you have the fairing and have "norma

Looks like your CHT's are right where they should be, if not very
slightly on the cool side. Have you checked the calibration of you Oil
Temp Sensor in boiling water? Is your Vernatherm operating correctly?

Hi;
I had a similar problem and checked my temp sender in boiling water. It

I have a S&W 8432-R mounted on the firewall of my RV6-A powered by
an 0-360A1A and Hartzell Prop. My oil temperature over the weekend was
175 deg. at cruise and 190 on my initial clime to 5500. Our temperature
here in Ohio was a hot,humid 92 degrees.

My RV6a flies with low oil temps, if anything. They seem to hover between
150 and 170 all the time. Configuration of the nose gear fairing doesn't
seem to have much affect, if any, as I've flown it with a bar nose leg, as
well was with the full leg and intersection fairing and not seen much
difference. I've actually been contemplating putting a small plate over a
portion of my oil cooler to bring the average temperature up 20 or 30
degrees to ensure the oil is getting hot enough to clean itself out each
flight.

The difference may be that I'm running an O-320 with 9.2:1 CR and EMag. The O-320
is normally a lot cooler on the oil than the 360.

Van's does indeed recommend "no recreational spins" for the -6, but that
doesn't mean "no spins." Van's specifically recommends that you spin test
your
-6 if you're going to do aerobatics, which it sounds like you plan to do.
Since aeros could lead to an inadvertent spin I think that's sound advice,
and
they put some guidelines in the plans for doing it.
Thx for the reply - but questions remain.
First - by the bye - I've been doing acro in, first, my Navy SNJ throughout
the 60s, and, more recently, for six years in my Yak-52. Never once got into
an unintentional spin, but then I've never done very sophisticated maneuvers,
such as what one sees at an airshow. So....not much likelihood of that. But,
anyway...
It seems to me that an airframe would be either suitably constructed to
accept spins, or it would not be. If Vans says you can test spin, then why not
a
recreational spin? Same maneuver. More impotantly, though, is my question as
to snap rolls and hammerheads. Doing just rolls and loops (and Cuban 8s, etc.)
gets a tad dull after a while. I guess I can get an answer from Vans, if
nobody else responds with an answer based on their experience.
Enjoy - Mike

The same warning applies to low temps as well as high temps. The sender
may be bad. So if you cover the oil cooler without first checking the
sender, you may have high oil temps and not know it.
It's not that much trouble to check and I'd recommend that everyone
check it at least once.

Checked mine by:
1.) Remove the sender from the engine.
2.) Boil some water. I then poured the hot water into a tin can.
3.) Checked the temp of the hot water with a thermometer, I used one
from the kitchen. I think they are called candy thermometers.
4) Put the probe in the hot water and have someone read the temp on the
oil temp gage and compare it with the candy thermometer. They should be
the same.
Using this method you can watch both temps drop as the water cools.
The downside to this is that at sea level the best you can check is
around 212 deg. But if your off by 15 deg as I was that will tell you a
lot.

I have endured this for far too long and am about this close (2 fingers abo
ut 1/4" apart) to investing in a nine tube cooler, if I can squeeze it in.
Aero Classic has one I think will fit.(like 3/4" wider).

How would you recomend checking the sender.

The same warning applies to low temps as well as high temps. The sender may
be bad. So if you cover the oil cooler without first checking the sender,
you may have high oil temps and not know it.
It's not that much trouble to check and I'd recommend that everyone check i
t at least once.

You must not have read my posts about improving exit air flow.
Lowered my oil temps substantially by opening the lower cowl and
adding louvers

No, it's not a binary choice. Each airframe has a degree of resistance to
entering a spin and a degree of difficulty in recovering (which also vary
according to loading and other parameters). Van said, "We recognized that most
RV-6 pilots would probably not have an extensive aerobatic background, and
could be challenged by recovering from fully developed spins." Hence, no
"recreational" spins. However, a pilot who expects to do aerobatics in the
airplane certainly can, and should, spin test it.
> More impotantly, though, is my question as to snap rolls and hammerheads.
Having snapped rolled a -4, and considering Van's comments on the -6's spin
resistance characteristics (which he says are good), I don't see any problem
snap-rolling a -6. I haven't done a hammerhead in either, though.
Have you read Van's Service Bulletin 02-6-1? It discusses the subject at some
length. Money quote about the -6: "In other words, a conscious effort was
needed to cause intentional spins, so accidental spins were deemed improbable
during normal flight operations, including sport aerobatics."

Larry,
I'd rather do it in very warm oil, just make sure it does not get hot
enough to catch fire (i.e. put the pot of oil within a pot of boiling
water).
Just don't like mechanical things in the oilsystem to be immersed in
water, that's all. Take a good thermometer and verify opening and
closing temps.
I am no A&P, so please get yourself a second opinion!

How do you recemend checking the varitherm? Boiling water again?

Looks like your CHT's are right where they should be, if not very
slightly on the cool side. Have you checked the calibration of you Oil
Temp Sensor in boiling water? Is your Vernatherm operating correctly?

Thanks for reply..............I am using the 7 tube cooler Van's
sells and it is mounted on the left rear baffle. This is what Van's
suggests for a 0-360. Surely I am not the only guy with this
"challenge?'
My CHT's are about 325=C2=B0F.........

You may consider building an exit ramp inside the cowling that looks
like a fairing around the whole nosegear cluster. This should smooth the
hot exit airflow quite a bit...
How are you CHT's doing when the oil is at 220 degrees? Perhaps you
just need a better oil-cooler arrangement if all else is in the green,
but not the oil.
do not archive

Subject: RV6-List: Oil temps??
I'm flying a RV-6A I built a few years ago and have always had oil
temps about 220=C2=B0F on 90=C2=B0 days..
I am wondering what the difference is between the RV-6 and 6A that
causes many 6A's to have elevated oil temps. Besides the nose wheel
structure in the cowling air exit that is. If you have a tri gear and
experience the same malady, do you have the intersection fairing between
the nose wheel strut and the lower cowl?? I do not as of now. My
baffles are sealed about as well as I can get them also. That is a
high pressure area during flight and I wonder if enough air is leaking
into the cowl to raise the pressure in the lower section, i.e. less
flow. If you have the fairing and have "normal" temps I would
appreciate feedback also.
Thanks fellas,
Larry , RV-6A N939LT at 2R2
