Has anyone replaced the incandescent bulbs in the speedo cluster and other guages with LED's...

When putting a 4.0L head on a 258, the fuel lines are usually routed close to the exhaust, creating a vapor lock problem in warm weather. Does anyone have experience with solving vapor lock with a shield kit like this...

I ran this setup for awhile, and the head failed due to valve recession after ~10 years, but the plugs were fine! My concern is longevity/reliability. I know these plugs lasted for me before, but can they go 200-300k miles? Does any know of them ever failing (assuming they were installed...

My priorities are: (1) cost / ease (2) reliability/longevity. (4.0's can go for 300k miles!) (3) Runs well and good mileage (4) Power / torque - I was pretty happy with my 4.2/4.0headMPI. Maybe a bit more power on the highway would be nice, but not a big priority. A straight 4.0 seems to be...

I replaced my failed oem Temp and Fuel gauges with "crown" replacements, and they were junk (only lasted a few years). I don't necessarily need the oem look. So what is the best way to replace bad gauges (Temp and Fuel) in the Speedo cluster)..?

Hey guys, I'm wondering if I push my engine too hard and/or are under-powered? Or if I'm just having some bad luck. I really don't want to be messing around with engine problems. I want something that works reliably. Here's what I'm running and here's what's happened: Original 258 rebuilt...

So everyone raves about OME springs (YJ strings on a CJ). But does anyone have a direct experience going from Pro-comp (or equivalent) 2.5" lift CJ springs to OME? I ask because my current pro-comp springs (with plastic slider disks between the leafs) are now about 15 years old, and perhaps...

I just had a new windshield installed. When they put the new one in, I noticed a bit of rust in the windshield frame. I also see that between the windshield gasket and the windshield frame, there is a gap...that water can go into. On the one hand, if left the way it is, water can go in, but...

How often should they be replaced? I've got at least 10 years (with lots of Utah wash-board road miles) on the current ones. The jeep does not do the obvious lunging over speed bums that a sedan with worn shocks would do. If anything, it feels STIFFER not softer. Time for new shocks?

Mines has suddenly gotten problematic, where I start to turn the key and suddenly it stick/stops and doesn't want to turn anymore and I have to jiggle it. This comes right at a time when I need to drive my Jeep daily for a few weeks. Anyone who has been through this... is this problem likely to...

I'm going for lightness, less weight. I hear that forged are "stronger and lighter" than cast, but everything I'm seeing online that fits a CJ is either cast or they don't say. Does anyone know of a forged aluminum CJ wheel? And if so, how much lighter are they really? a few pounds? And what...

I'm about to go for lowering gearing. I'm looking at these three options... The 4:1 D300 vs Klune vs Black Box. Something I want as part of this upgrade is smooth shifting in-out-out of low range. My current D300 (2.6:1) does not do that. It usually binds and is hard to shift out of Low Range...

In my never ending mission to give my Scrambler more modern comforts... Is there a slick (easy) way to sound-proof the engine compartment / firewall to make the engine less noisy? (I already have a carpeted floor) thanks!

Hey engine guys! If a 258 peak torque is around 2100rpm, and a 4.0 is around 2800rpm, then what about: Hybrid engine: 4.0 Head, Cam and MPI conversion on top of 258 block (bored 0.030) the 1983 258 gets torquey due to it's crank and rod geometry the 1995 4.0 gets it from it's better head/cam...

Anyone know what this is??

I know this is splitting hairs, but if I could pick a ratio for my set up, it would be 3.92. Yes, 3.73 or 4.1 are very close. But 3.92 would be ideal. I think 3.92 is available for D30's but not for AMC20, does that sound right? For example, D30...

(1) For a long time, I've been thinking of the 5th gear in a 5-speed manual as the "top gear". In other words, the gear to use at your highest speeds. Also, on the Novak website, they talk about "gear span". On other words, it's not how low your lowest gear is, but how big is the span from...

I keep seeing that a '83 Scrambler could have come from the factory with 27", 28" and possible 29" tires. Does anyone know if this is true? What is the most likely stock tire size on a 3.31 ratio axle? Also, if there were different sizes, would 27's and 29's have been on different axle ratios?

So my '83 Scrambler came with a passenger seat that tilts forward, but a fixed drivers seat. I grabbed a driver's side tilt bracket off a CJ-7, and turns out it's NOT a direct fit (the left side does not line up with the holes in the floor). I thought when I got it that it was from a late model...
