Can anybody on the list remind me where I can get that valve that closes off the scat tube going to the oil cooler (so the oil will warm up faster on a cold day)? I remember buying one in the past, but can't remember where.

Just so we are clear here, The vernatherm is open when it is cold and the oil is not flowing through the cooler. Thus cutting off the air flow to the cooler will not make it warm up faster. Up north folks do limit air flow to the cooler in winter so the straight weight oil does not over cool and get so thick it doesn’t want to flow through the cooler. Just so you warm weather folks know.

Not the whole story. Just like automotive cooling systems thermostats
there is a bypass passage for oil in the aircraft engine, AND the
passage to the oil cooler. The vernatherm ONLY controls the bypass and
does nothing for the path through the cooler. So the bypass gets
closed as the engine nears the rated oil temp of the vernatherm, but
the oil cooler lines are always open. So if the oil cooler is getting
20 degree air across its full face, it may stay mostly congealed until
the vernatherm closes the bypass. If airflow is restricted to the
cooler, the cooler will in fact warm up faster.

While it is true that the open Vernatherm does not prevent oil from going
through the cooler, the differential viscosity between the warm engine and
the cooler oil cooler directs almost all the flow back through the engine
and not through the cooler. Especially true if you have preheated the
engine with one of the plug in types that heat only the engine and not the
oil cooler.
It has been my experience in cold weather flying that if you limit the
intake air into the cowl enough to keep your CHTs up where they need to be,
then the oil cooler pretty much takes care of itself. Large aluminum
restrictors in front of the front two cylinders or duct tape over part of
the cowl inlet does the trick.
Without some air restriction, it is very easy to get the front cylinders
over cooled or shock cooled upon decent and landing.
What is really needed IMHO is a valve to control the airflow into the cowl.
Any of you inventors out there have any ideas?

Cooling air for engine is very specific to a given cowling design and
you need to be careful to not get hot spots in unintended places. It
is much safer to regulate oil cooling air. While you think a
thermostat is sufficient, when it is really cold, restricting the
airflow makes a big difference. In Alaska it was necessary to block
about 2/3 to 3/4 of radiator on cars to get sufficient cabin heat and
engine up to normal temps. But those were operated to -60 and colder.
In all but emergency situations piston aircraft flying stopped between
-20 for personal stuff, -40 for air taxi and charter work. Cowl flaps
are better for regulating CHT than any restriction on the inlet side.

Well, only part of the story John. What they control is the pressure
differential across the cylinders, which controls the airflow through
the engine compartment. When you have a funnel, it doesn't matter how
big the top end opening is, only the size of the little opening at the
bottom. If the top of the funnel is full, ain't no more getting in
until some goes out the bottom. Great over simplification of what
happens, but works well enough for discussion purposes.
I really think that most of the hot weather cooling issues could be
fixed with properly sized/designed cowl flaps. But WTFDIK, still
working on wings?

Before the thread gets diverted, who won the debate? Does the oil cooler valve provide utility? I have an extra push pull cable available if its a good idea since I didn't hook up the FAB alternate bypass valve.

Don't know who won - but I have a homebrew butterfly valve on the air inlet
to the oil cooler on my 8A and find it very useful. I'll have a similar
valve on the 10.

I thought I would post a few results from my oil cooler valve from Nonstop aviation. I also have the large oil cooler.
Before installation I was seeing oil temps at around 175-180 f with OAT
around 50-70. Once temps got cooler between 35-45 f I was seeing lower
temps around 170-175. And a little lower with even colder temps. Even in a climb at 2200FPM and full power to 8500 122kts temps would not go over 175f.
I called Bart at AeroSport Power to discuss the oil temps and if he thought the valve would help. His answer was yes give it a try.
I installed it and can adjust from wide open to closed. I now can get my
oil temps up to 192f with it fully closed at OAT of 24f. I can open it and within a minute or so temps will start to go down.
I do believe this to be worth installing and does what it claims.
I have been told from the Aeroshell reps that your oil temps should be above 180f for at least 20-30 minutes to burn off any condensation /moisture.
FWIW
