I bought an 84 CJ7 in May 2022. Was running rough and wouldn’t drive over 30 mph. Carb was some weird Weber (water choke??). Decided to buy a Chinese motor craft 2100 to replace it. I have not been working on it and just started again now. It runs but I cannot figure out how to connect the...

I was pulling out of my driveway for PT last Friday and as I was depressing the clutch on my '84 CJ7 it made a popping sound and then it sputtered and died. I started it back up and the clutch still had resistance but I could not get it into gear. I wasn't able to get underneath it before my...

I changed the oil in my 78 CJ5 today and notice even after idling for about 20 minutes the oil pressure was still around 50 psi at idle but the needle kept jumping all over the place. Also when driving it sits at 80 the whole time. I looked underneath the Jeep while idle and did notice what...

I have a 76 CJ5 with 54K miles. I got it 5 years ago with 49K and had the dealership here swap out the 232 with a 258 crate engine. I’ve had to repair little things here and there since then. 2 weeks ago I noticed that the ignition module had seen better days and decided to swap it out with a...

I'm hoping someone can give me a little insight into reasons for a cam gear failure when the old distributor gear doesn't look all that bad. I recently picked up this 79 CJ7 through a small car lot that was selling it as sort of a favor to friend of a friend kind of thing so I don't have any...
