that there is a valve, one would think not necessarily car specific

Looks like a throttle body. The center plate rotates to allow air into the intake. This assembly looks like it happens to use a counter-weight instead of a spring to close the plate off throttle.

Heat riser baffle. What do I win?

We need to bring back parts that can be "fixed" by hitting them with a wrench. More for fun than functionality.

Exhaust manifold heat riser valve. GM? Small block?

mechanical throttle body?

That is what I thought as well. Not sure though.

It's pretty car specific. It's a touch too fancy to go on most carbureted engines that aren't on cars, though you'd see this on some industrials. Heat riser valve.

travis got it. Heat riser baffle. I googled his answer.

RamblinRover Luxury-Yacht > Mattbob
10/16/2014 at 12:39

Nope. Not enough there to make use of. It's *like* a throttle body, but it's an exhaust part.

RamblinRover Luxury-Yacht > ADabOfOppo; Gone Plaid (Instructables Can Be Confusable)

It's not actually a throttle body. The setup has a counterweight opposed by (effectively) a thermostat coil, so it changes state when hot.

It's a heat riser valve - to heat up a carburetor so that it gets to vaporizing right faster.

RamblinRover Luxury-Yacht > crowmolly
10/16/2014 at 12:41

Yep, GM smallblock. Well done.

Yeah, that's a bimetallic spring. Expands with heat to open the valve.

kanadanmajava1 > RamblinRover Luxury-Yacht
10/16/2014 at 12:45

My Packard has similar. The coil thing is a bit tired and the valve is making silly noises when the engine is warmed up.

ADabOfOppo; Gone Plaid (Instructables Can Be Confusable) > RamblinRover Luxury-Yacht
10/16/2014 at 12:47

Yeah, that's really old.

I hope to get a '48-'50 some time in the next five years. Yours is excellent from the few pics I saw.

This sort of valve became drastically less common once cross-flow heads predominated. Much easier just to heat the carburetor with pre-thermostat coolant, if needed.

The car this is off of - an SBC Impala or Nova - was actually somewhat unusual in having one. The original primary use of these is in the exhaust manifold on an engine with the intake right over exhaust (reverse flow). On one of those, it's really easy to set up and makes sense, but those engines don't rev well and became less common. Some engines have a tube from the exhaust and one of these to the manifold, but this simple automatic style mostly died in the 70s.

Trevor Slattery, ACTOR > RamblinRover Luxury-Yacht
10/16/2014 at 12:52

Wow dude, you went long on this one. 70's part? This type of stuff was all over early emission British cars. To me it was the Brits trying to get car through emission that really gave rise to the stereotype of poorly tuned and maintained cars.

Jedidiah > RamblinRover Luxury-Yacht
10/16/2014 at 12:54

It's a heat riser from a early 60s or before Chevy.

They rattle and stick shut so everyone removes them.

RamblinRover Luxury-Yacht > Trevor Slattery, ACTOR
10/16/2014 at 12:55

This one is actually As Seen On Chevy, but yeah. It's a heat riser damper to heat up a carb. These came up first for engines with shitty carbs, suffered a decline with the shift to cross-flow heads, then had a brief revival for emissions uses before dying at last.

RamblinRover Luxury-Yacht > Jedidiah
10/16/2014 at 12:57

Yep. They're also standard fit on a lot of brits in the "in exhaust manifold" style. When we replaced the cracked manifold on the 2.25 gas in my cousin's '64 Rover, the replacement didn't have one. He has a wire-heated Solex "0F" carburetor, so he will not miss it for even a second.

camaroboy68ss > RamblinRover Luxury-Yacht

Ahh I have loads of those laying around, my 68 Camaro still has one on it

I figured it'd be familiar as hell to you, at least.

Jedidiah > RamblinRover Luxury-Yacht
10/16/2014 at 13:05

I don't think they were really necessary. The tubes that pulled hot air from around the exhaust manifold, the exhaust crossover in the intake manifolds, and the bimetallic chokes did a pretty good job.

The only thing I can think these things were good for were on the ancient reverse flow straight sixes

Kinja'd!!!

Those models are still quite affordable except the convertible. They are really pricy.

The intake heating was really easy as the manifolds could be easily bolted together. I'm a bit surprised that the car hasn't been suffering from fuel boiling in the carburetor but it might be consuming the fuel with such speed it doesn't have time to boil...

There is a convertible I've been keeping an eye on not 2 hours' drive from my house. A plain Victoria, not a deluxe model in any way, and with some serious rust issues in the floor to be addressed, but no holes through and a mostly straight body. $7,000, and listed by the owner of an auto dealer, so even eligible for loan! I've not convinced myself yet I should look at it more seriously, but it is sorely tempting. The convertible is solidly my preference.

Another convertible in rough condition sold at auction in Alabama fairly cheaply a month or so ago.

kanadanmajava1 > RamblinRover Luxury-Yacht
10/16/2014 at 13:35

That's quite affordable convertible if it isn't even rusted through. Even my California sourced sedan has some small holes. Buy it quickly!

The most tempting convertible that I found was a top model Custom ('50?), but it was seriously rotten. A good sedan would have had to be sacrificed to get that one fixed.

The TinyTohruTruck has coolant plumbed to the carb so it heats up with the engine.

RamblinRover Luxury-Yacht > Tohru
10/16/2014 at 13:52

As do quite a lot of cars with carbs or even injection that aren't reverse-flow head inline throwbacks. The setup on later Toyota R22s to heat up the EFI sucks particularly.

Tohru > RamblinRover Luxury-Yacht
10/16/2014 at 13:53

I know it's for the exhaust, but it reminds me of Ford's Intake Manifold Runner Control valves.

Kinja'd!!!

Tohru > RamblinRover Luxury-Yacht

The roommate has a Toyota 22R that's running Yamaha R1 carbs on a custom intake. Well, it would be running them if the motor itself was running.

RamblinRover Luxury-Yacht > Tohru
10/16/2014 at 13:55

So deliciously wacky. It's like they found a way to half-ass an ITB setup and make it more complicated and expensive at the same time.

This would be the infamous Dogapult's-22R-Celica-It'll-Run-Again-Someday-I-Swear 22R, I trust.

It ran when it came to my house. Poorly, but it ran.

Now the motor's in the car but not even bolted in.

He said if it's not done by first snow he's going to burn it and scrap it.
He has the day off and he's in his room watching CinemaSins.

I have the marshmallows.

The Ford 2.0L SPI engine ('97-'02 Escort, early Focus) used this as well.

The IMRC valves crack open at like 3000 rpm.

Right. You run an Escort with rust-custom race exhaust (broken flex pipe) and you can really feel it come up on the cam at 3k. All 110hp come alive.

RamblinRover Luxury-Yacht > Tohru
