i was given this diagram to set my carb up:

IMG]C:\My Documents\car stuff\bmp hoses 2.bmp[/IMG]

now the question is will it work?

the pcv will not be hooked up and the line going to the air cleaner wont be there either due to an after market air cleaner.

also what about all the open ports now? do i plug all of them. doall of them suck air, or do some blow air?

im not sure what to do. i dont want to make my driveability sufer, however i dont have a stock motor any more.

what do i do?[

 

First of all, we need some details on your setup. CCC Q-jet? Holley?

You need to either convert the picture to .jpg format or you can email it to me.

 

i think this is it

the carb is a ccc quadrajet

 

the big problem is this diagram tells me to eliminate almost everything except, the EGR.

i have taken all the pollution controls off the car, except the high flow cat and the EGR. will this setup effect my drivability?

 

Probably not significantly, if at all. Any vacuum port that is not being used must be capped. They are all for vacuum, none of them have air coming out. You should be able to find caps for them from a local auto parts store, get the non-rubber ones if possible. The thermal vacuum switches near your thermostat do not need to be plugged if there are no hoses going to them. The port behind the carburetor on the intake manifold goes to the air conditioner/cruise control line, if you have neither you can cap that too. The tubing that fits into the back of the carb goes into your brake booster, you should leave that alone. The EGR in that diagram is correct. If you're still using the ECM like you should be with that carb, you need to connect the vac sensor like the diagram. Do you still have a charcoal canister? What year is your car? Also, can you give more details about your engine and setup?

 

Why on earth not?

I can't think of any reasonable reason for removing the PCV system.

 

You should hook up the PCV. For the crankcase air inlet (what used to go to the air cleaner), you can either put a breather cap or route it to the filter side of your aftermarket air cleaner.

Since you have an aftermarket air cleaner, you won't need the line going to it.

The charcoal vapor canister is a good idea, both for the tank vent and the carb fuel bowl vent.

 

m car is an 86 z28
305 LG4 swappd for 350 .040 over = 356

cam, heads, forged pistons

i dont want to dissconnect the pcv system, but the diagram say to.

also what is this charcoal canister that several of you hve refered to.
never heard of it.

the only canister i have are for radiator flud, windsheild fluid, and i think the crusie control(located on drives side next to radiator)

 

The charcoal canister (also called vapor recovery canister) is opposite the battery (in the same place, but on the driver's side).

I don't know who gave you that diagram, but I wouldn't take it as the only way you can do it. At best, is shows what you can get by with if you retain CC controls, EGR, and dual-snorkel air cleaner.

Forget the diagram - hook things up the way they should be.

 

What do you want to keep? It's easy enough to figure out what goes where...

To start with, PCV goes to that big honkin' port on the bottom of the carb under the fuel inlet

 

If you tell me whether or not you have an EFE valve on your passenger side exhaust manifold where it bolts to the y-pipe, I'll make you a better diagram.

 

Here's how the hoses are supposed to be hooked up.

Leave the PCV system on there and hooked up properly. It costs you nothing, and will keep your engine cleaner inside, and your oil cleaner, and therefore your engine will last longer and run better with it that without it. You need either the line going from the air cleaner into the pass side valve cover (the right way to do it), or one of those stupid breathers that always spews oil all over the top of the VC. The way it works, is that the PCV valve lets the engine draw some of its incoming air through the valve, which pulls vapors and combustion products and condensation out of the crankcase; and the other line, that normally comes from the air cleaner, supplies fresh clean filtered air into the engine to replace what is drawn out through the PCV valve.

The charcaol canister is a large cylindrical object on the driver's side very front of the car next to the radiator. It has nothing to do with the cruise control.

I agree with five7, screw all that and hook it up like it's supposed to be. If you don't know what stuff does, don't go ripping it off and trying to "alternate engineer" (RIG) it somehow.

 

the only reason i need a new setup is because i swapped motors and took the air pump and exhaust manifolds out. so now i have headers and NO air pump.

also i ahve these vaccum connections(two sepperate sensors w/ 2 vaccum connections on each) that go to the wate neck. what ar they and do i need them.

the computr no longer turns the fan on or off, the only thing the computer manages is the carb, and other stuff i probably dont know it controls.

 

With what you've mentioned, this diagram should be fine (I hope you don't mind my using your pic RB83L69). z28crazy, the "sensors" that you mention are labeled as TVS's in the diagram. The EFE TVS is the one in the water neck.

 

what does this "purge tvs" look like?

what are its colors, shape, ect

could anyone take a pic of this valve in their car so thati could get a better understanding?

 

The purge TVS (Thermal Vacuum Switch) screws into the intake manifold either near or on the thermostat housing. There are TWO TVS's in that area; one for the EFE flapper in the exhaust and one for the canister purge. Trace the lines coming from it to determine which is which.

Alternately, I believe the purge one is bigger in diameter and has a colored top (blue or green).

 

Go to this thread and scroll down to the picture near the bottom. The purge TVS is the one labeled Thermal Vacuum Switch in the pic. The EFE TVS is in the thermostat housing, though it's not in the picture.
