I'm working on my 83 Ramcharger. I'm having a hard time finding the right exhaust manifold does anyone know if it is supose to have a heat riser on it also anyone know where I can by a book for 83 Ramcharger? I'm in California if that helps

I think the heat riser is on the driver's side manifold, which kind a makes sense since that's where the snorkel of the air filter housing is routed.
However, on my 88 TBI there is something refered to as the butterfly valve on the bottom of the passenger manifold, which is also supposed to route warm air back to the engine at startup. I don't know if that is a newer thing or not though...plus mine is broken for a couple of years now and I always managed to get through Smog.
A Factory Service Manual for your 83 RC can be found on ebay every now and then. Just keep looking...

Hey Zempsey welcome to the site -
Ok lets check on what we are taking about (some people mix up terms on these parts). The accordion kinda alum. tube running from the sheet metal on the exhaust manifold to the snorkel on the air cleaner; that ass'y is called the 'heat stove' You will need it for CA smog visual inspection part, although I've never had any one check to see if it actually works, but the parts will need to be there. The heat riser is the valve in the exhaust manifold near where the exhaust pipe hooks up, that is themro controlled (the spring lookin thing). I never had anyone check for this, but by law it's supposed to be there (whatever...) It is useless peice of junk that will mess up your engine if is stick shut.
My 83 pick up (31
has these on the pass. side.
You should be able to find this stuff in a jy.
As far as the manual goes - do a web search for factory service manuals there's a few places that have them.

What I need is a knew exhaust manifold that has a built in heat raiser, The exhaust manifold I have now is cracked,
I bought a knew one from Napa Auto Store but it didnt
have a heat raiser they siad I didnt need one but than I clled dodge they said I do so I took it back got my money back.
I'm going to take friday off and go to a few wrecking yards and find the right one. I have the aluminum tube that connects to the air cleaner I found that at car quest a couple of years ago.
Ok, this might be different on an older truck (though I don't think so), but I just looked this topic up in my 88 FSM and it says:
the manifold heat control valve is on the passenger side exhaust manifold and routes exhaust gases into the heating chamber of the intake manifold in order to help with fuel vaporization on startup.
The air heater or stove is on outside of the manifold and heats up air that is then routed into the air cleaner housing, also for help with cold start.
For Smog, you definitely need the air heater for the visual inspection. With the other thing, I am not sure, because if you had smog legal headers I think you wouldn't have that valve however they usually have a heat stove available or you can put one together.
As far as where to get a manifold with a manifold heat control valve, I haven't found a place yet that has them, except your friendly Dodge dealership, but the passenger side manifold for my 88 was around 600 bucks

Santak, I'm still not sure what you are talking about - even though you repeated it 7 times 
There may be a differance between the carb. truck and tbi models (you do have tbi right ?) there is a heat 'riser' in the intake manifold to warm the carb. and choke, but that is different than what I think Z is talking about.
Z - your truck will run fine with out the heat riser, mine is wired open. (most of them are burn out in these old rigs anyway !)

hey Z,
look at http://www.Car-part.com
they could probably give you areas to look at, if not then i have a couple of these laying around i might be able to hook you up with.
i would try locally first since shipping would cost almost what a used one would cost

I'm talking about the heat raiser that is built in side if the exhuast manifold on the right passenger side.oldmanram said:Santak, I'm still not sure what you are talking about - even though you repeated it 7 times

I bought a brand knew one but it didn't have the heat raiser built in side of it so I had to take it back they are hard to find
I'm going to some wrecking yards tomorrow to get the right one.

so is it better to just keep it wired open then when I have to smog it just un wire it ?
Mr oldmanram so you keep your heat raiser wired open. I'm wondering if I should do that as well
when I get my exhaust manifold tomorrow.becouse if it stays shut it can mess your motor up right.
and than when its smog time just untie it shut?

Good question....( don't know if I have a good answer !) First I would check your new manifold to see if the heat riser is free (or if it even has one) The 'valve' is just a butterfly valve inside (sort of like the choke in your carb.) the spring thing on the outside is a thermostatic (sp?) spring - closes it when cold, and opens when hot. Push it open and closed see if it's free (note which is open so you can wire it if you want) If it works you may want to just leave it, or wire it open, and if there's no plate inside, I wouldn't worry about. If it sticks shut you will know it cause your engine will run like crap (MAJOR exhaust restriction). As far as smog goes, I'm not sure what to tell you - My guess, and thats a guess, is that they won't check it. The engine must be at full operating temp. for the smog check, so this thing would be open anyway. I hate to say too much about smog stuff, 'cause as I'm sure you know, different parts of CA test differently and some places are much more strict then others, and I don't know about your area. Hope this helps !zempsey said:
EDIT: Oh Boy ! Hold the phone - I may have screwed up big time here.... I just found out some of you guys may have a vacuum operated heat riser, and is a seperate peice that hooks to the bottom of the manifold between the mani and the tail pipe (the one I am talking is built into the manifold, and works manually) although it seems to work the same way. Now I don't know which you have ? I have NEVER seen one of these vac. things - maybe this is what Santak was talking about.... very sorry if I have caused confusion....
