Oil temperatures

[Garry Wright]

I've gone thru the archives and not come up with anyone struggling with
this one. My oil temps are generally too low. At an OAT of -20*C and the
air intake to the oil cooler fully taped off, the best I can get is 160*
oil temp. As a result, oil pressure is a bit hi at 80psi and of course
boiling off any water in the oil is not happening.

FOKM is an O320 well installed by Wayne O' and hi temps are definitely
not much of a problem. Thing is Wayne only used FOKM in the summer with
heavy oil and now at the low winter temperatures we can get around here
she just doesn't seem to warm up. Exhaust and head temps are normal but
cool quickly (shockingly so) when the throttle is closed - calls for a
little judgement in getting her down from altitude. I would like to pick
up about 30* in oil temp so that flying down to -30*C is feasible.
Beyond that I get a little prickly.

It seems to me some of the guys in even colder areas must have solutions
to this sort of thing.

Today was one of those glorious days that all pilots look forward to.
Light breezes, a bit cool (-17.5*C on the ground), partly cloudy and
open skies. Floats are off for now so I measured her cruise at about
118mph according the the GPS. Thats about 20% better than on floats if
faster is better??

Gary...take some duct tape and mid cowl inlet put two strips of it
overlapping about 1" across each inlet horizontally. Take the top/bottom
edges and fold them in slightly onto each other to stiffen it up and you'll
have block offs that look kinda venturi shape. Go out and fly it and see how
it does. Play with the tape until you get the temps up considerably even if
the CHT's hit the 400+ mark if you can get the oil to come up. Once you have
it working make an alum piece to match what you did in tape. That's the step
I never did with mine last year and flew the tape all winter and it never
let go. Then when I removed it last spring I set it somewhere to make
patterns and don't remember where that somewhere was.... so have to start
over again this winter.

Gary,
I have read that you can get low oil temps due to congealed oil in the oil
cooler. Also have you checked the calibration of the gage?

[Wayne G. O'Shea]

The O-320's oil cooler is on all the time when running a screen and cold oil
bypass plunger (plunger is there in case it's too cold to get thru cooler),
unless there is a Vernatherm screen housing installed and a vernatherm
installed in it. This installation in FOKM is the screen and bypass plunger
that gives the best cooling in the summer. The Vernatherm installations
cause the oil temps to run hotter due to the fact that the oil is being
forced thru a smaller temp controlled orifice (like a car thermostat) to get
to the cooler. If his cooler is blocked with Congealed oil he should be
running hotter..not colder...I would think.

Gary, as Al points out you might want to stick the sendor in boiling water
and confirm temp is accurate. Don't think it has been checked before.

If the tape doesn't work Gary you could always pop a hose off the cooler and
one off the engine and put the line from outlet to inlet to get rid of the
cooler all together for the winter. Line left on cooler just loop it back
onto the other cooler fitting to keep it clean and sealed. Wouldn't be very
easy to flip back though if you happen to go somewhere and the outside and
oil temps go thru the roof though.

HI GARY

I have the same problem. Wayne has a good idea with the duct tape. Was up to
see my mechanic for 100 hr. inspection. I put a piece of aluminum under the
oil coolere to restrict airflow. This helped a little.

Good luck

Murray

Maybe I'll venture down to High River this weekend. We have avgas ay our
airport now so I don't have to come for fuel anymore.

Hi Garry !

The standard 'fix' is a "winter kit" of covers for various openings.
On FOKM, that would be a ring of aluminum, running around each front
air inlet, extending about 1" into the opening - this reduces the size of
the opening evenly, restricting airflow. These extra baffles are usually
.025 or .032 aluminum, and screwed to the nosebowl (captive nuts,
or just PK screws). You could start with a heavy cardboard pattern,
taped in place.

Most likely, you'll see lots of these around on other aircfraft.

In extreme weather, I've used asbestos cloth jackets that
cover the oil tank, and fasten with snaps (easier on Continentals !).
(Of course, it'd be difficult to get asbestos nowadays - but there must
be some fireproof quilted material you could try ...)

I just have the bypass plunger and screen on mine, and also have
the problem of needing to adjust how much tape I have over my
cooler to control my oil temps. And because I have the speed
cowl, I need to remove my top cowl each time I want to do that. I
do have a spare Vernatherm which I could install. Or I have also
been thinking of rigging up some kind of flap mechanism that I
can control from the cockpit. Then I can warm it up quicker in
cold weather and open it as needed in flight, once I have boiled
off the moisture. Of course, I am still not talking -20C weather,
as you won't catch me flying in those conditions. But even at +5
or 10C, I need to have my cooler mostly taped off. It is only in
the hottest part of the summer that I have no tape at all on it.
My cooler, BTW, is mounted at the rear of the baffle.

Yes, and very informative and useful site, Roger. Funny looking
engine, but...;>))

Because my oil cooler is attached directly to the rear baffle, I
would be doing a hinged flapper valve on the inside of the baffle
area. Will have to look at it again, but I think I had enough
room in there to cover most of the opening. The butterfly valve
should do the trick for Garry, though.

You should look at the photos that Roger Hoffman has
put on his construction
site of the butterfly valve he set up for his... very slick.

I just have the bypass plunger and screen on mine,

and also have

the problem of needing to adjust how much tape I have over my
cooler to control my oil temps. And because I have the speed
cowl, I need to remove my top cowl each time I want

to do that. I

do have a spare Vernatherm which I could install. Or

I have also

been thinking of rigging up some kind of flap

mechanism that I

can control from the cockpit. Then I can warm it up

quicker in

cold weather and open it as needed in flight, once I

have boiled

off the moisture. Of course, I am still not talking

-20C weather,

as you won't catch me flying in those conditions.

But even at +5

or 10C, I need to have my cooler mostly taped off.

It is only in

the hottest part of the summer that I have no tape

at all on it.

My cooler, BTW, is mounted at the rear of the baffle.

The O-320's oil cooler is on all the time when running
a screen and cold oil
bypass plunger (plunger is there in case it's too cold
to get thru cooler),
unless there is a Vernatherm screen housing installed
and a vernatherm
installed in it. This installation in FOKM is the
screen and bypass plunger
that gives the best cooling in the summer. The
Vernatherm installations
cause the oil temps to run hotter due to the fact that
the oil is being
forced thru a smaller temp controlled orifice (like a
car thermostat) to get
to the cooler. If his cooler is blocked with Congealed
oil he should be
running hotter..not colder...I would think.

Gary, as Al points out you might want to stick the
sendor in boiling water
and confirm temp is accurate. Don't think it has been
checked before.

If the tape doesn't work Gary you could always pop a
hose off the cooler and
one off the engine and put the line from outlet to
inlet to get rid of the
cooler all together for the winter. Line left on
cooler just loop it back
onto the other cooler fitting to keep it clean and
sealed. Wouldn't be very
easy to flip back though if you happen to go somewhere
and the outside and
oil temps go thru the roof though.

congealed oil in the oil anyone struggling with an OAT of -20*C and the best I can get is 160* 80psi and of course temps are definitely FOKM in the summer with we can get around here temps are normal but closed - calls for a altitude. I would like to pick -30*C is feasible. areas must have solutions pilots look forward to. partly cloudy and her cruise at about better than on floats if -------------------------------------------------------
