Hello Arty:
Not an issue...
Leave the duct tape OFF.
If you think about it, you drop 2 degrees per 1000 feet.
So 11 x 2 = 22 degree change.
What is the surface temps?
It's summer time right!
So let's say 80 F
80 - 22 = 58 F
Lets drop to 70 F
70 - 22 = 40 F
STILL not a problem.
FORGET ABOUT IT!

Nope - no thermostat or mixture control.

| Subject: | Re: Drop in Oil Pressure |
Hugh,
I suspect,as Roger does,that you have a bad oil pressure sensor.
A while back, I was reading low oil pressure on my gage in my aircraft so
I decided to check it with my air compressor gage.(using a rubber tipped
air nozzle on the air hose) I removed the sensor ,set 60 lbs of pressure on
my air compressor, applied it to the oil pressure sensor, and found that the
gage in the aircraft was reading 10-15 lbs low from the compressor gage.
Now I KNOW that the compressor gage is probably not that accurate but I
still decided to put a new sensor in the aircraft anyway. Surprise ,it agreed
with the compressor gage on testing and I was back up to 55 lbs at cruise
again.
You might also be able to install a temporary oil pressure gage to check
for accuracy of your existing system.
You also might,have carbon or some other type of grit holding the ball
open on your oil pressure regulating system.(easy to check) I kind of of
doubt it but maybe. Installing the new cone system,as Roger mentioned, might
help also. Just some ideas.

Hi Arty,
I haven't seen you around on any forums as of late. Nice to hear you still flying.
I agree with Barry. Many people use the tape on the radiator in the colder
months which is fine. When you fly this summer leave the tape off. You will most
likely over heat on the way to 11K. Why fly so high? You should be able to
go through passes even around the mountains. The only time I ever get that high
is over the Rockies.

Heater control valves are fairly common on some engines. (not the Rotax) They are
an in line valve with a cable. Opening or closing regulates the flow thus the
heat exchange. They can usually be purchased at an auto parts store. If you
can't find it at the US auto parts store then try the foreign parts store. They
were more common overseas many years ago. I suppose you could also make your
own, but make sure you use a metal one and not a plastic that may be subject-able
to the heat or be prone to failure from the heating and cooling cycle.

The problem is if you forget this valve closed, when the engine needs more
cooling, you will simply fry it

Ok,
The coolant goes out of my hot engine, then to the heater. After the
heater, I have a brass ball valve that I can reach in the cockpit. Then
it goes to the radiator and then back to the engine. I try to keep my
water temp around 180 to 190f.

That seems like a lot of variables. Especially when you add the human
factor in forgetting to monitor it and forgetting to open it.
Why not just install a simple automotive temp valve in series and you are
done.
Of course you will have to manufacture a housing.
Doesn't ROTAX have something for this?
AND if you go the route of the automotive thermostat you could also put a
ball valve across (shunt) the thermostat in case of thermostat failure.

| Subject: | Re: Drop in Oil Pressure |
Agreed on previous advice. $15 for a auto parts direct reading kit. Install and
run up. You'll probably find it is the sender, not the engine
I had a high reading then low reading and erratic sender- 100+ psi high and 20
psi low. Once removed, the old sender bench tested fine w/ steady air pressure
and no vibration on an ohm meter.
Install the new sender, good for a few years or a few hundred hours.
Should not be a bad ground or loose connection if it gives a steady reading as
installed currently, but always good to check. Some places you will find say
use no thread sealant to avoid case grounding issues. Other say to use a sealant.
I used white #59214 permatex thread seal, YMMV.
Found these ohm values today on the net:
Rotax 912 UL running the Standard VDO Oil Pressure Sender 360-004, or 29/12 stamping
on the hex along w/ a date of mfg of in 2 digit month/2 digit year.
VDO 0 - 10 bar oil pressure sensor, Bar psi Resistance (Ohm's)
BAR=PSI= OHMs on sender
0 = 0 = 7.2

Good luck! I was worried about high oil pressure possible meaning a bad bearing,
then the low pressure meaning lost bearing. That was no fun watching the oil
temp like a hawk while returning to land.

| Subject: | Re: Drop in Oil Pressure |
Making an oil pressure gauge setup to mechanically check oil pressure while checking
the electric oil pressure. (This post isn't for you if you already have
a mechanical oil pressure setup to your instrument panel)
If you have an electronic oil pressure gauge in the cockpit and you think you pressure
is too low and don't no if it really is low (rare) or if it might be the
sneder or ground then here is an easy to set up check.
Hop on down to the hardware store. Buy 5' of 1/16 copper tubing. buy 4 1/8-27 NPT
to compression copper fittings. Buy a dial gauge that reads up to 100 psi.
Buy a 1/8 tee fitting.
Take out the oil pressure sender (threads are 1/8-27 NPT). Put one of the compression
fitting on the end of the cooper tube. Screw that into where you took the
oil pressure sender out. Cut the tubing about 18" out from there and install
the tee with one side of the copper tube going in and the other going out. (two
compression fittings here). Now screw in your oil pressure sending unit on
the top of the tee. It will be grounded through the copper tubing. On the end
of the copper tube use another compression fitting and screw on you mechanical
gauge. Don't tighten it. Start the engine and allow any air to come out up by
the gauge and when you see a drop or two of oil you know the copper line is
full and the air is out. Now tighten the gauge. Run your engine up and compare
the electric signal oil pressure with the mechanical one. This is about a $20
diagnostic tool.
See playing with Tinker Toys as a kid does help later in life. So give them back
to your kids and remember when.

Ok,
The coolant goes out of my hot engine, then to the heater. After the heate
r, I have a brass ball valve that I can reach in the cockpit. Then it goes
to the radiator and then back to the engine. I try to keep my water temp
around 180 to 190f.

You got to explain a little more about your system a Ball Valve between yo
ur heater and engine is not enough, do you have external cooler/Coolers?
in this system. also what Temp are you controlling the heater or the
engine Temp ?

Nope - no thermostat or mixture control.
I guess I should look into both.
Thanks, Bob - I should have guessed that you'd be able to respond to this
question.

Not sure you'll need anything else besides that, but there are some people
making louver systems for some radiator setups. here's one: http://www.th

How about mixture control?

Do you have to purge the oil system after you replace the oil pressure

Hugh,
I suspect,as Roger does,that you have a bad oil pressure sensor.
A while back, I was reading low oil pressure on my gage in my aircraft
so I decided to check it with my air compressor gage.(using a rubber
tipped air nozzle on the air hose) I removed the sensor ,set 60 lbs of
pressure on my air compressor, applied it to the oil pressure sensor,
and found that the gage in the aircraft was reading 10-15 lbs low from
the compressor gage. Now I KNOW that the compressor gage is probably not
that accurate but I still decided to put a new sensor in the aircraft
anyway. Surprise ,it agreed with the compressor gage on testing and I
was back up to 55 lbs at cruise again.
You might also be able to install a temporary oil pressure gage to check
for accuracy of your existing system.
You also might,have carbon or some other type of grit holding the ball
open on your oil pressure regulating system.(easy to check) I kind of of
doubt it but maybe. Installing the new cone system,as Roger mentioned,
might help also. Just some ideas.

Carlos, There's that, and there's the fact that a piece of carboard and a
few feet of duct tape is about 5 cents. I run a Honda Sabre radiator with m
y
582 on a Kolb Mk III and I blocked half off for winter months. January 1st
it was 32 degrees for the high temp in southern Kansas and I flew for an
hour. The temps never got out of the green zone for the engine, but they
sure did for me.

Hi Hugh,
No you do not need to purge after changing the oil pressure or oil temp probe.
You will only drool a little oil.

Arty, See other reply and add this. The only time I see a problem with temps
on my 582, and I pull the cardboard / duct tape block off when the temps get
above 50 for daytime highs is on approach. The temps will drop to 100 / 110
or so even if I try to maintain 3000 RPM to keep pumping some heat into the
engine. Even then my only concern is doing touch and go landings. Makes me
nervous going to full throttle from that low a temp. At cruise the temps are
in the green arc and not a problem.
If your flight path is along highway 80 you should be able to stay below 10,
000. Things are pretty flat from Rock Springs on east to Cheyenne even
though you go over the Continental Divide twice.
