vaccuum and emission hoses - WTF!!!
Hey guys,
So ive got the problem of the coil sorted, and the car now at least starts (albeit very rough as it has zero emission or vaccuum hoses hooked up).
Ive got a gregorys manual here, which I am attempting to use to refernce whilst hooking up all the various hoses under the bonnet (not water), however they seem to be pretty generic (eg the decel valve on my car has two hose connections, whereas the book only shows one).
Can anyone help me with an intuitive and easy to understand diagram or explanation on what needs to go where (this is a stock standard car - including factory air filter assembly), in a 1980 MK2 Rs2000 manual.
Thanks guys - i really look forward to anything anyone can provide me. This is doing my head in, and the project is SOOO close!.
Dave

I've got a couple of pics of a standard engine that might help. PM me a regular email address and I'll send them to you.

Hi Guys, Just following on from the above, im still having trouble getting these hoses right. Ive had a look at the pics Flighter sent, and went and had a look at Whooligans car, but 30 years of people fiddling has meant all three are really quite different!. I have many hoses that im trying to find answers / homes for, and id be really appreciative if someone could help get this sorted. I have outlined the current setup for each area, but am quite sure this is wrong in some regards. 1) Charcoal Cannister: Current Setup - Currently the top passenger side hose goes into a return pipe of sorts that heads back to the fuel tank (I believe). The top drivers side hose currently is connected (via a T-Piece) into the hose running from the inlet manifold to the Oil Seperator. And finally the bottom connector has nothing hooked up to it at all.  2) Vaccum Advance Module on Distributor Current Setup - Currently the connector on the dissy module closest to the firewall is going to the small connector on inlet manifold, whilst the connector closest to the radiator is going to the base of the carby.  3) Decel Valve Current Setup - The decel valve obviously has two connectors. One on the side, and one on the bottom. Currently the one on the side is running to a pipe on the top of the carby (not too sure what its called, but its the same size as the fuel delivery and fuel return pipes - It is a standard RS2000 carby). The connector on the bottom of the decel valve currently has nothing plugged into it.  So, from these pictures and descriptions, im hoping some of you might be able to help me get all these hoses and pipes to their correct homes. Currently the cur does run, but its quite roughly and wont idle smoothly. I also have a European spec 38/38 carby to put on it soon, so this will leave the hose currently going to the decel vavle without a home. Any suggestions on what to do with this?. I believe some people have removed the decel valve altogether (and blocked it up I assume with something?). Im not sure if I want to do this for originality reasons, but I believe its an option? Many thanks in advance guys. Dave

Dave, you can't have only a portion of emission devices connected. won't work and will make your engine run bad. So you have 3 options 1. get every bit of emission control and correctly connect up. 2. Make existing emission control parts look like they are connected, but plug up the lines internally (ball bearings etc), this will appear as connected(functioning) to those who don't know. 3. remove emission control parts altogether. I responded to your specific questions below, hope it helps.... Cheers davus
Hi Guys,
Just following on from the above, im still having trouble getting these hoses right.
Ive had a look at the pics Flighter sent, and went and had a look at Whooligans car, but 30 years of people fiddling has meant all three are really quite different!.
I have many hoses that im trying to find answers / homes for, and id be really appreciative if someone could help get this sorted. I have outlined the current setup for each area, but am quite sure this is wrong in some regards.
1) Charcoal Cannister: Current Setup - Currently the top passenger side hose goes into a return pipe of sorts that heads back to the fuel tank (I believe). The top drivers side hose currently is connected (via a T-Piece) into the hose running from the inlet manifold to the Oil Seperator. And finally the bottom connector has nothing hooked up to it at all.
To rear of car connection is correct
Bottom is correct, normally has 2-3 inch length hose on it, like an overflow hose...
The third connection is wrong, since you don't have all the other parts either disconnect or ball bearing it.
BTW the t piece you have it connected to normally is connected to hot air flap via a thermal switch in bottom of stock air cleaner.
2) Vaccum Advance Module on Distributor Current Setup - Currently the connector on the dissy module closest to the firewall is going to the small connector on inlet manifold, whilst the connector closest to the radiator is going to the base of the carby.
As you don't have all the emission gear, only run one vac hose to distributor. this should be ported vacuum(spout at base of carby facing rocker cover) to outer connection on vacuum advance unit. Leave the other disconnected. This will give correct vacuum advance operation.
Note!! Don't forget to recheck you ignition timing it may be out if you have set it with hoses connected...
3) Decel Valve Current Setup - The decel valve obviously has two connectors. One on the side, and one on the bottom. Currently the one on the side is running to a pipe on the top of the carby (not too sure what its called, but its the same size as the fuel delivery and fuel return pipes - It is a standard RS2000 carby). The connector on the bottom of the decel valve currently has nothing plugged into it.
Side of decel valve to carby correct
Bottom of decel valve normally goes to manifold vac via thermal switch etc as it is intended that decel valve only operates at normal engine teperature......choice is yours what you do since you are replacing the carby without relavant connection.....the easiest would be to just uscrew valve from manifold and plug with correct plug.
So, from these pictures and descriptions, im hoping some of you might be able to help me get all these hoses and pipes to their correct homes. Currently the cur does run, but its quite roughly and wont idle smoothly.
I also have a European spec 38/38 carby to put on it soon, so this will leave the hose currently going to the decel vavle without a home. Any suggestions on what to do with this?. I believe some people have removed the decel valve altogether (and blocked it up I assume with something?). Im not sure if I want to do this for originality reasons, but I believe its an option?

Get rid of it altogether! It is easy to do this so it doesnt even look like anything is missing. I will post up a photo of mine in the next few days and you will see what i mean. The forst and most obvious part is to get a TC Cortina thermostat housing that doesnt have the drilled hole for the vacuum tree.
This gear did stuff all when the cars were new except restrict power and there would be lucky to be many of the constabulary that would even know this difference provided you make it look like nothing is missing e.g. vacuum trees with nothing connected to them etc.

Thanks for the replies guys. I just have a few questions.
RS2000 -
1) I actually do have the stock air cleaner with the hot air flap. Im assuming I can just connect the T-Piece hose (part of the oil separator connection), to the hot air flap? If not, I see no need for the canister as all it would have is the hose to the rear of the car?
2) When you say "to outer connection on vacuum advance unit", do you mean the one closer to the radiator?.
Gdub -
Thanks very much!. I would love to see some photos of your setup, and possibly a little description of how it all works?.
Thanks guys.
Dave

Hot air flap goes to thermal switch in the bottom of air cleaner then from thermal switch to the said t piece.
Agreed if you don't need charcoal canister to 'look' connected then get rid of it.
No, the outer connection refers to one closer to inlet manifold.(outer as in further away from distributor body.)

The charcoal canister is one item of the emissions control system that serves a useful purpose without inhibiting performance in any way, so why not retain it and help keep the air a little bit cleaner?

its a valid question , with no justifiable reason to do away with it. It will be kept. Dave

I thought you didn't have all the parts to connect it properly????thus removing it. it wont be useful unless connected correctly! cheers

Yep get a pre pollution themo housing to get rid of the 'tree'
You can do away with the flap on the air cleaner and no one will really notice.
The carbon canister is not much use without a return line and the other bits but looks good to the constabulary.
The one I'd sort is the vacumn advance, otherwise have the dissy re-curverd, it seemed to fix a hot webered kent engine I had....
Hope that hasn't confused it any more.....

RS2000 - looks like I'm getting confused here :). You are right, I don't have all the right parts. I was getting confused with the "T-Piece" arrangement we spoke about in an earlier post. I do have all the right air cleaner parts to connect that TPiece hose into.
Aside from the return line, and open hose on the bottom, where does the other connector on the charcoal canister go?.....or is that back to the multitude of switches etc....that I don't have?
Sorry, I do admit I got confused there

Haha The t piece is where the hot air flap connects to...... Return line??I am assuming you are referring to fuel tank vapour line. The other line is purge line, it connects to a purge control vacuum switch, manifold vacuum, temp switch (vacuum tree) and ported vacuum. Cheers

Thanks RS 2000 - yeah I do mean fuel tank vapor line (thanks for correcting my terminology).
Sounds to me like there is no really easy way for me to hook up the last line on the canister, in an effort to leave it there.
As per your suggestion, I am going from the ported vacuum (on the bottom of the carby), to the outer connection of the vac advance. I don't have any vacuum switches, but I do have the vaccum tree on the thermo housing, and the vacuum connection on the manifold. Would I be going backwards if I hooked it up to these?.
Or perhaps just straight to the manifold vacuum (in an effort to hook it up to "something" to make it "look" like its in use) - without affecting performance?.
