Search Results for ‘258’

After toying with the factory Carter BBD for more than what it’s worth, and trying to get the well received Chinese copy to work was the final straw for me. Ever since I got the Jeep back in September 2021, I knew I was going to covert it to fuel injection. The last time I tinkered with a “CJ”...

Any suggestions on where/how to find a replacement 258 for my CJ? Powertrain evidently not making them any more, mine has a crack in the block. I live in MD. Any assistance greatly appreciated - have a shop that can do the swap but can't find an engine!

No spark on plugs. Need help figuring out what voltages should be on original ignition system. Measuring 12vdc from red wire on coil + to battery ground with ignition on, 10vdc while cranking. If I pull the green- and red+ off the coil and measure across them I get 4vdc with ignition on and 5vdc...

So, I have been crawling through the forum and I had a issue with my jeep having a strong strong fuel smell. So I read up that it can happen with clogged jets on the Carter BBD. So I took it off, cleaned it up and rebuilt it. The strong smell went away, but I still have a light fuel smell. I am...

I bought a MC2100 last year, and finally got around to installing it in my 85 CJ7 Laredo, which had a weber 32/36, and have a few questions. I thought I had purchased one with an electric choke, but i do not see where i'd hook up the choke wire- is this a manual choke (first 2 pics)? There are...

Question, I have a 1992 YJ that currently has a 2.5 4 cyl in it and I just acquired a complete 4.2 6 cyl (258) that came out of a 1988 Wrangler. Im sure the engine swap is possible but what all will i need to do to accomplish this, or have i bitten off more than i can chew. Thank you for any...

OK- so it's sick again. I replaced the carb with the Howell TBI and did a Team rush upgrade. I also replaced the old charcoal canister with a new one from Delorean (plus about a million other things!). Anyway, everything has been running great and I even bragged a little to the family...

OK. So I have an 86 CJ-7, 258 w/ Carter BBD. Typical setup. It acts like the carburetor is plugging off as has been described in many posts. So I removed and cleaned the venturi tubes, idle tubes, nozzles, etc. It runs fine for 5-10 miles, then starts to run rougher and rougher at idle, until it...

I currently have a 4.2L I6 in my wrangler that I may need to rebuild soon. My wrangler is completely decomputerized (nutter bypass, ECU removal, weber carb, etc...). I know the advantages of fuel injection, I just do not want to do that on this particular project. If i bought a used 4.0...

I've got a 1985 CJ-7 with the 4.2L AMC I6 that has a weird issue I haven't been able to find mentioned elsewhere. The PO replaced the stock carb with a Weber 38 DGAS (I can't figure out why he didn't just use the standard 32/36 like everyone else), and it ran like crap, lurching around whenever...

Been working on a bunch of little things over the winter, and this past week, I finally took her out to road test her. Drove her a couple miles, and when I got back, bam... leaking coolant. Was hoping for a head gasket. Nope... crack in the block. Any way to fix her? (JB Weld? Hubba Bubba bubble...

All I've pulled the carb and looking to rebuild myself. I've never done a rebuild before and need help from the experts. First, what all needs to be removed before immersing the carb in solvent? Second, what should be reused and what should be replaced? Do I need to replace the electric...

I am replacing the RMS on my '86 CJ7, 258, T5. My flywheel inspection plate was beat up pretty bad from the PO, so I decided to replace/repair it. When removing the clutch linkage bracket I realized that another bracket was coming out at a 90 from the bottom bolt. I've searched everywhere and...

First off thank you everyone your help. I've only owned my jeep for a couple weeks and already I've used this forum many times. Thank you to all. So I purchased my 89 Wrangler 4.2 a couple of weeks ago. I test drove it for about 15 minutes and it had no abnormal noises, good oil pressure...

Hey all, I have an 88 YJ 4.2 and want to remove all A/C components. Before it's thrown at me: no, I do not want on board air and no, I do not want to replace it. I live in Orange County and have next to zero need for an A/C. The compressor seized up on me a few months ago in the middle of the...

So I have been rebuilding a fiberglassed 77 CJ5 for past few months. Having problems with the cooling system... It has a mildly built 258 with a 73 block. All new coolant system(radiator, cap, neck, pump, T-stat, hoses, gauge, and sender). Once it warms up it will max out gauge and stay there...
