1983 CJ7 Laredo, 258 inline 6 with stock everything else. Have a Dana 300 trans with and Dana 30 front axel and AMC 20 wide trac rear end with a T-5 tranny.
Did the nutter bypass and took off the cat.
I have the AMC 258 i6 / 4.2l I6 motor in my 83 CJ7 ...but live in the socialist republic of California. They have smog galore on this thing....go thing it's got AZ registration where it will live once i finish fixing everything. The cat is gone and the air tube on the driver side is removed but the other one that goes up to the passenger side just broke. I have two vacuum lines that are supposed to open that part. If I just block those vacuum lines will it not screw with the running of the motor since it just let warm exhaust in to the air cleaner area??? Thanks for any help with this.

P.S. planning to take all the smog stuff off but a jacked up pinon threads have put that on the back burner.:chug:
 
If you can afford a smog legal fuel injection kit, like a Mopar or Howell, most of the factory emissions stuff can go in the trash. The factory service manual has a complete vacumn line routing. You might get away with blocking those vacumn lines, the later 258s have a very complex oem emission system and there is lots of things that can go wrong. Hopefully you are not still using the original cat and muffler. Good luck with that.
 
Probably the single biggest drawback of the mid/later year CJ's for those of us in smog states is the pathetic emmisions :dung: on them, 70-80's manufactures were learning as the tried to keep up with tighter standards and just added more hoses and :dung: as they went.
Torxheads advice is the track I took and was a hard pill to swallow at the time but well worth it to me now.
 
Actually, the 83-86 systems were the easiest of all to work on and understand.
Pulse Air it was called.
The biggest drawbacks were upon cold starts, a lot of moisture and condensation would work it's way up into the tubes and checks valves, eventually corroding out the tubes, check valves, and even the air cleaner base where the hoses attach.
The nightmare systems were 1981 and 1982 AMC 258 i6 / 4.2l 's, at least for us California guys.
 
Torx....I want a fuel injection system but I need to replace the ring and pinon on the rear axle as the threads came off with the nut when I went to replace the oil seal. Like Sas said things rot out...the air inlet that was there rusted out and then when I went to change it it broke off. So i can remove the whole and it should be good. Just got to plug the holes in the bottom of the air cleaner. Hagar are you having and issues with California being a pain with smog? ..Thanks Guys. :chug:

California is a pain with anything and everything :mad:
But being a native, I hope to someday soon see Calif in my rear view mirror.
 
Buy property in Az....then you can get your jeep registered there. Just a though....:D
 
Guys, I know how you feel about Smog equipment. But I must say this, if you want to continue registering your Jeeps for the road leave the Smog stuff on your vehicles. The government isn't going to give up on their requirements and it's just going to get worse. I know the drive to remove the stuff is strong, if you can't resist don't toss the parts, someday you or the next owner just might need them. All over the country Jeep owners are trying to keep their beloved Jeeps on the road and they are looking for emission parts to keep things legal. I know this because I just got done digging up enough parts to keep my Jeep legal. Yes, I know, there are ways to get around the law, but I hate the hassles involved. Keep those parts, someday they could be worth their weight in gold.

Although I feel your pain brother the problem is a lot of those Californians that leave California move up here to the great Northwest. They must miss the lunacy they just left as rather than melding into our civilization and customs they tend to work hard at Cali-fornicating our way of life and the next thing we know a whole bunch of new ridicules rules and regulations are enacted chinking our freedoms just a little bit more. Now don’t get me wrong I think we should all be free to move about the country as we please but become part of the fabric, don’t try and change the weave.
 
I will be a political refugee.
I'm no threat to you or your lifestyle....the politicians are.
You're barking up the wrong tree.....
What happens here in California, will eventually effect every other state.
In some cases, it will be within a couple years; in others it may be 20 years or more. But it will come.....mark my words.
 
I have an '81 (nightmare year!!) CJ7 Laredo with the AMC 258 i6 / 4.2l 6 and live in California. I decided to go with the Howell Fuel Injection, paid a little more for the CARB approved one for California Emissions and also went with a HEI Distributor. Big Pile of SMOG :dung: including wiring, Vacuum Relays, junk Carburetor, junk Distributor etc. in a large pile on the garage floor. I also put a new Flowmaster Catalytic Converter and Muffler at that time.
WOW! it sure makes a difference on how the Jeep runs. Well worth the expense.
I do have some of the MOPAR stuff from a junkyard take-off, if someone wants it.
PS have gone through SMOG twice so far with no issues!

Political refugees always welcome as long you don’t forget why you left where you came from. Greenies need not apply, we have to many of them already.
