Swapping an 8 cylinder into your CJ, YJ, or TJ
The benefits of such a swap should already be obvious. Some people swap in for the power, others might swap just for the challenge, or to display mechanical prowess. I personally did mine because at the time I saw no other options. Someone had a 350 they didn't want, I had a straight six, I didn't want. All I needed was time and money. Another reason might be purely to make a vehicle that does better at shows...we won't talk about that. Domain: http://www.jeepland.net Rating: (0/5)

The Lowly Oxygen Sensor
The first O2 sensor was installed in 1976 on a Volvo. Yawn. It needed to be replaced every 20,000 miles. That was the inauspicious beginning of the lowly oxygen sensor, so it's no wonder most gearheads either scorn them for their roll in pollution control, or at best, look at them indifferently.

TJ 4.0L cold air cowl intake
A cheap and relatively easy cowl intake which will allow you to ford at least 3' of water.
My jeep is drawing air from the cowl vent in front of the windshield. If I don't show it to you, you'd never know it was there. It's waterproof as long as I don't completely submerge the jeep up to the windshield. Domain: http://www.jeephorizons.com Rating: (4.75/5)

TJ Radiator Replacement
Most folks that read the on-line TJ forums are not surprised to hear when someone reports that their TJ with 20k or 30K mile on it had to have the radiator replaced. The upper and lower plastic tanks are crimped onto the radiator core itself and it only seems to be a matter of time before this style of radiator starts to leak at the crimped seam. Mine recently did it....and the timing could not have been worse. The TJ was parked at the City Market parking lot when my wife mentioned that "&we have steam coming out of the grill"&. Now normally a radiator problem in a parking lot is not a BIG issue. But, this was THE City Market parking lot.....you know, City Market in Moab, Utah. THE place where 4 wheelers meet up each morning to decide on which trail(s) to run that day. And on top of that, it was a Sunday morning. Luckily, the seam held and once the plastic and metal parts stabilized (ie., they finally heated up and expanded enough to seal the leak) and I was good to go.

Top Dead Center (TDC) Tech
The TDC sensor has been the cause of many headaches on the XJ cherokee. I can think of many stories of Jeep that were rendered unstartable because of this inexpensive sensor. In fact I remember a story a friend related to me, he had driven to Lake Isabella with some friends to go Four wheeling. At one point he realized the Jeep would not start. They tried everything to get the Jeep started except the TDC sensor. After many attempts they gave up and rented a Uhaul truck and trailer to tow it home cost after all was said and done $300.00. The sad thing in this case was that if he would have had an extra TDC sensor none of this would have happen. Domain: http://www.off-road.com Rating: (0/5)

TR Ignition Upgrade AMC V-8's
It will work with any AMC V-8 from 1978-1990. These engines used the same Motorcraft distributor for all variations. There are three different levels for this upgrade.
1. Basic Upgrade. No modification required to any hard parts. No cutting of any wiring harness. Does not increase spark energy, just makes sure it gets where it's supposed to go and helps smooth out the idle.
2. Mild Performance Upgrade. A small amount of modification required. This upgrade builds on to the Basic Upgrade for faster response times, better starting, and much higher spark energies.
3. Extreme Performance Upgrade. A fair amount of modification required. This is an upgrade that should only be done after the second upgrade has been done.
This upgrade uses as many stock, off the shelf parts, as possible, so they can be replaced at any parts store. I hate to be out in la-la ville and not being able to get parts. Domain: http://www.jeepgod.net Rating: (0/5)

Troubleshooting A No-Start Problem
There is nothing more aggravating then getting into your car and finding it will not start. According to Murphys Law, of which I'm a firm believer, this will happen at the worst possible times. Like when you're late for work, have a car full of screaming kids or when it's 200 degrees below zero out.

Understanding the odd-fire V6
I've been hearing the term "odd-fire V6" ever since I got into the Jeep hobby. You hear the term a lot because the optional Dauntless 225 that went into the late 60's CJ5 is such a popular swap into other Jeeps. I'd always wondered what people meant by "odd-fire", and when I bought an M38A1 that had been the subject of a '76 Buick 231 V6 swap my curiosity became even more pronounced. But it wasn't until I decided to change my points type distributor to a GM HEI type that I became determined to find out just what "odd-fire" really means. I searched high and low on the web, even purchased a Buick repair manual just to try and gather information, but try as I might I couldn't find any information on what was so odd about this engine. So finally I sat down and put my noggin to work one day and with a good bit of email help from Bill Lagler, not to mention a lot of scribbling, I think I've got it figured out. It's actually fairly straight forward once you understand... So now, without further adieu, this is what's so odd about the Jeep/Buick "odd-fire" V6. Domain: http://home.off-road.com Rating: (5/5)
