CJ has all vacuum lines essentially capped off

So I got a 1984 CJ7 for $800 bucks on friday. The previous owner complained that it wouldn't run right so I popped the hood and it was pretty obvious the issue, all but a very few of the vacuum lines were even hooked up. In fact most ends where they should be were capped off. I know that replacing all the lines is a nightmare, but I've found a couple diagrams online. What I really want to help me out is if someone else happens to have an 84 cj7 with a 258 inline 6 (5speed manual) could take a couple shots of there engine bay while the air filter is off so I can get a decent look at how some of the vacuum lines are placed/ran along the engine. Thankyou for your time and any help you can offer. - Anthony

So I'm Editing again, I've got some pics up of the jeep and the engine. Would anyone be willing to help point out what some of these things are because I'm having a lot of trouble getting this done and I can't figure out what some of these ends that are capped off are. Here's the URL for the photobucket with all my photos. http://s954.photobucket.com/albums/ae27/SeaJay7/

I have the 258 inline 6 with 2 barrel carb. The only thing i have hooked up now is the line to the pcv and the timing advance. Every thing is gone. I even took the egr off, capped the hole, charcoal canister off, plugged all the holes on the carb. I'm in Kentucky with no emmision checks. It runs great. I threw away half a 5 gallon bucket of stuff. Set the timing, adjusted carb, like i said runs great now.

Amen! I have done the same.

I'm in Virginia and I have to pass all the emissions tests, or atleast to get it inspected :/ After that I'm safe to undue it all again, but I have to get it together right to get it passed inspection. Do you have any photo's of your engine bays before you capped everything off?

I don't have any pics, but I think a Haynes or Chilton's would have a diagram. Check one out from the library.

Good luck! If you do not plan for it to be a daily driver, skip it and register it as an antigue. Thats what I did. Your '84 does not have to pass the sniffer test, but for a safety inspection they will look for ALL emissions components and evidence of tampering (pulse air system, cat, EGR, etc..). Antique does not require inspection.

Just an FYI, your gas filter is in upside down. This can cause long cold starts because the gas can siphon back to the tank when it sits causing vaporlock.

The filter is supposed to sit level with smaller return line off the top of it. This way on a hot shutdown, any vapors produced get blown back to the tank off the top of the filter rather that vaporlocking the gas line.

Ouch! Ok, someone posted that is just has to look right so I wonder if you hooked up all the basics for a good runner and physically cleared out anything else so it didn't look disconnected if you could pass the visual?

For starters you should see if the emissions computer is still trying to run things. To see, you need to look 'way' down on the drivers side fender under the washer bottle at the ignition module and it's plugs. The module will have an orange, purple, green and black coming out of it to one plug. The 'harness' side of this plug will 'not' have a purple wire in it. If the purple wire coming out of the module is spliced with a new wire, then the computer has likely been put out of your misery. If the purple wire just stops at the plug, then the computer is still connected to the carb and distributor.

Here are some 'basics' for vacuum for a good runner: Vacuum Hose Hook Ups - JeepForum.com

I am plagued by the long cold starts. Pictures are always easier for me. Could you post a picture of what it should look like? Thanks.

Thanks Mike. I'll see if that solves the problem when I get home.

I just got slapped down in another thread by a moderator for posting the photo of it sitting properly from the owners manual (Copyright issue) and have mine in pieces right now.

Look at the above photo in post #6 and then think you can just grab the filter and twist the sucker clockwise until that bottom side hose is up top.

That way the center line goes to the carb and the top line goes to the return line.

Wow, thankyou all for the very quick and detailed responses. I wish I was able to reply with how all my hoses look in comparison in a photograph. I'm gonna check on the running status of the emissions computer also. I guess I could get it registered as an antique, but wouldn't I be limited to only putting x number of miles on it a year?

Here is a link to the factory service manual for yours. It should have all the lines set up properly in it: 84-86 Factory Service Manual... - JeepForum.com

wow.... crazy.......


seajay,
if you decide to go antique, make sure you read all the fine print in the DMV guide first. there are a hella lot of stipulations. how may miles, how far from registered address, how many times a week you can drive it. since you have to pass the sniffer I suppose you are in NVA and i can see you passing the same officers of the law more the 3 times a week and getting questioned.
i almost bought a 68 bronco up in manassas before i got my jeep which had antique plates. getting it out of antique status looks to be almost as much of a PITA as complying with the rules to begin with.
just the old 2c worth.

oh and welcome to the club!
