Keep oil warmer during winter flight

It is the duct to the oil cooler. Blocking it off keeps cold air from going down to the cooler thus keeping the oil warmer.
@NielRomeoGolf, there is a little vane assembly in the duct visible in that photo (at the tip of the red arrow). It catches some of the air and sends it ... where?

Oh, that's what he was asking. Good question. Here is the engine on my 81 with the cowls off. The plate is blocking flow to the orange duct leading down to the cooler. I don't see anything on mine teeing off.

It wouldn't be visible in that shot. It's on the other (inboard) side.

That's an interesting cooler setup. With such a big blast tube robbing air from the top how are the CHTs, particularly #3?
It would be easy to put a butterfly in that duct and a cable in the panel to control it. Reduce air to the cooler as required.

This is from a higher angle. Still don't see anything. Don't have a picture from the other side.

What's that blast tube pointed at under the left mag?
Is it pointed at the mag itself? I think I see one on the opposite side pointed at the right mag.
This is the opposite side. Has a tube too.
Traditionally, the #3 cylinder on Lycoming O360s run hotter than the other cylinders, primarilly due to the oil cooler inlet, behind it.
I always get a kick out of the cheesy brake fluid reservoir in the Archers... -Skip

Yes! This is why late model autos are using lighter weight oils to meet the EPA mileage standards but thicker oil is MORE protective (higher film strength) than thinner.

If you were to trace that onto paper and post it as a PDF, I'm sure any other Archer owner could easily copy it with a set of tin-snips and a small plate of aluminum.

Hey...be nice
. My vintage Bonanza uses a cheesy can too.. I can only imagine these cans might have been leftover containers repurposed.Ever heard of Kingsford Charcoal ? This company began at Ford Motor Company when Mr. Kingford was told to find a use for all the leftover bits of wooden wheel spokes...they were used to make charcoal.
On my Jacobs engine, one oil cooler is blocked in the winter, the other I can close via a control cable.
On the Archer, you can block the scat tubing rather easily on the backside of the baffle as well. I had a friend who placed a empty tin can inside the scat at the oil cooler end...oh well....

That was a club plane I flew up until September 2009. The former club plane, a Piper Archer II, is now in Australia and registered as VH-KLU
Thanks, did it come with the airplane? Was there a designated place where it was stored?
Merry Christmas and Happy Holidays to all and thanks for the replies!

Think it came with the plane, as it's mentioned in the manual. Having said that, my '73 180 (Archer 1) didn't have one when I bought it. I fabricated a duplicate using some sheet aluminum from the Home Depot Aviation Department. It's stored in the tool bag in the back of my plane when not in use. It's not the most critical part to get right. There should be a couple small holes at roughly 10 and 2 o'clock on the baffle that the tube you are showing in the pics runs into right above cylinder #3. A plate that will cover the hole and bolt into those two holes will work fine.

I went for a flight to get cheap fuel, Monroe, WI the other day. Yes, I was going to fly anyway, so didn’t only fly for the fuel.
The surface OAT was about 45, as I recall. The oil was a bit warm on the way over, 230 or so. I opened cowl flaps to cool some, worked. On the way back I took my dense foam blocker out, temp was fine. Mine is easily removable, I could also fashion one that only covers 1/2, whatever.
When I had my Warrior I used near 50 degrees as my cutoff point, usually took it out there or above. I only fastened it with the screws that were easy to get to, never a problem.

I found a better angle of the tube. Sure looks pointed at the mag (far right middle of the picture).

I’ve never seen blast tubes for conventional mags. Thanks for the pics. FWIW blast tubes are standard practice for Pmag installations to cool the electrical module.

To the best of my knowledge, it came with the plane. The club kept a small hard sided tool tote in the baggage compartment that held cleaning supplies and spare oil and such, this is where it was stored.
