Ok, I am trying to clean up my mess of lines and I am using this diagram with the stock carter carb.


Is the EGR what is pictured off the drivers side of the carb center of this pic??


I know the CTO valve is in the center of this mess:


I assume this can go, or do I need to keep these???

[rustywrangler]

Just let me know if I have this straight gents. Can I remove whatever that is on the back of the manifold??

Rusty, That diagram is all you need for vac lines. The EGR is the silver diaphram with the single vac line on the intake below the carb. The CTO has the 4 ports on it and is screwed into the intake manifold just forward of the EGR. The 3 valves on the back of the valve cover can go as well as the 2 on the firewall. The silver valve in the center of your last pic is the decel valve and it can go also.
I'll see if I have pics of mine less to vac lines

That would be great, thankyou man. I have not found any pics of a setup post nutter and vac cleanup.

Here's some old pics. The circled yellow is the CTO and the arrow points to the EGR..

I know the CTO valve is in the center of this mess:

The EGR is (in the pic) to the right and down a bit from the throttle return springs, and has a tube coming off that looks like it's got some sorta spiral wrap to it.

The CTO is under that ball of vacuum hoses.

Howell Engine Developement has a good diagram of what ports are what on the CTO. I couldn't figure out how to get a direct link, so go HERE and then to page 6.

And the can looking thing with the big red X I believe was actually removed as part of a service bulletin. I remember reading about it somewhere, anyhow, mine didn't have one when I got it.

I'll see if I can snap some pics of the cleaned up vac line tomarrow. Since I'm using the stock carb and air cleaner I had to screw the air door open. I don't use the heat riser from the manifold and get all the air from the stock location by the ds headlight. Basically. I have ported vacuum to the CTO which when warm feeds vacuum to the EGR and purge valve on the charcoal canister. I have a ported vacuum line to the distributer from the 2nd ported vac source on the Carter. I have manifold vacuum to the 4wd disc tee'd into the vacuum line to the brake booster. Everything else is gone. There is that vacuum line at the rear of the manifold for the heating dampers that goes right into the firewall. I'm pretty sure I didn't have to do anything there. I did leave the vacuum pod under the battery and tied that into the feed to the tcase switch for a steady vacuum to the disco. I did have to cap off the other port on the pod.

Don't you just love the Nutter rusty? haha. I know I do. xD

I would also like to see some pics because I just finished doing the nutters on New Years Day. ha.

Thankyou gents. this helps alot. Burner, I do appreciate the help. My current issue is I am a bit confused on how to run the crank case breaters. The rear one just pukes oil into the air filter so I think I need to figure something out there. The front one went to the back of the carb and T into the mess of lines.

I hate knowing too much about jeeps and then running into something that confuses the hell out of me.

[rustywrangler]

Burner, I notice you do not have the sol-vac setup. Was that due to the HEI or just nutter???

[Burnerman]

Rusty, I ditched the stuff on the air cleaner, It didn't seem to me that it made much sense without the manifold heater hooked up. I've run it this way for 2 yrs. It did go thru NJ inspection with just the EGR,charcoal can and new cat. As far as the crankcase breather stuff I just left it alone. The charcoal can is tied into the vacuum line to the PCV valve and the rear breather goes into the air cleaner. If you're getting oil puking up into the air cleaner you either have a bad PCV valve or a ton of blowby. The PCV valve should be sucking air into the manifold while the rear hole lets filtered air into the crankcase. Check the PCV hose for leaks. When I redid the lines I just bought about 8' of each size hose and ran new. Don't try to reuse the old stuff. Just run the new lines like the top diagram you posted and cap off the unused ports on the carb. I'll snap some pics of the CTO and where the lines go and the PCV lines for you tomarrow.

Much appreciated man, helps alot.

I posted some pics in my gallery. Here's a few. I tried to label the lines.

EXACTLY WHAT I NEEDED MAN,


I see you even cleaned up your wiring on the front side as well.

[Burnerman]

I had a bunch of unused wires in the harness to the carb. I cut out the stepper motor wires, temp sensor and knock sensor wires that were used with the old emissions computer. The CJ help site (LINK) is where I got the wiring diagrams for what could go. I didn't get into the main harness along the firewall. I did remove the old ignition module harness after the HEI. To me getting rid of all the unused wires and vacuum stuff makes it easier to work on it and less stuff to confuse when troubleshooting. There are plenty of " what's this" and "where does this wire go to" threads on the forum from PO's that left the old disconnected stuff in.
If you need any other pic's just let me know. Maybe a sticky thread for post Nutter vacuum lines? The pics are in my gallery for linking.
