Moses, I have watched your videos regarding how to approach a stroker motor. I have read tons of info on the internet, and I've seen many calculators for quench height, combustion cylinder volume, etc. It really is baffling to me, and I've begun to realize I could invest a lot of money and end up with an engine that doesn't work. Is there any identifying info on the block that would allow you (or someone) to write me a "recipe" for what parts I need to build up a stroker? I'm realizing that the added weight of the full size truck axles and 38" tires are going to necessitate more power. -
For finding TDC on the compression stroke without the starter functioning, a time-honored approach is a whistle that fits into the spark plug hole for #1 piston. Spark plugs removed to ease crankshaft rotation, this device allows rotating the crankshaft by hand in the normal direction of rotation while listening for the whistle as the piston rises on the compression stroke. Note: If you have brazing or soldering equipment, you can make this tool using an old spark plug shell with the porcelain, electrode and ground strap removed. Braze or solder a metal whistle to the metal plug she -
I have a 95 YJ 4 litre let's running extra rich. It will foul out the spark plugs with carbon fouling within a few minutes. Let me start at the beginning, I bought this Jeep running terrible. I was told it had a dead battery while jump starting they hooked up the cables backwards. I thought this was probably true due to the fact that both alternator fuses were blown. I drove it nine miles home and went through over 4 gallons of gas. Most of that ran out the tailpipe or was dumped into the crankcase. The number 5 and 6 injectors we're running fuel anytime the key was in the run position. -
I've owned a 2004 TJ Wrangler Sport for a couple of years now and it has been stalling in 2nd gear the last few weeks. I gave the car to Berwick jeep service centre and all they tell me is that their computer doesn't show them what's causing it and that there is no problem. Has anyone had this issue? i know its not my driving!!! -
AMC/Jeep® always leaned forward in both car and utility vehicle designs. By the mid-'80s, the CJ needed a contemporary replacement, a vehicle with wider track for handling and a better highway ride package. The Wrangler emerged just as AMC sold to Chrysler, and the Wrangler and XJ Cherokee were the profit items Mopar wanted! The Wrangler four- and inline six era represents huge growth in the 4WD/SUV market overall, and there are huge numbers of enthusiasts, owners and buyers who can build a "community" at this forum! —Moses Ludel At left is an '87 YJ Wrangler, leaf springs articulating

I've been a Jeep enthusiast since 1997. My first Jeep was a 1982 CJ8 Scrambler. One YJ and 4 TJs, the current one being a 2004 Rubicon with 52,000 original miles and trail modified. I have been experiencing the famous P0301 trouble code very intermittently unless it was cold outside, then it was steady. Rain or shine didn't seem to change anything. I live in Minnesota where winters are cold. Started with the obvious tune-up, copper plugs and the coil rail. Battery connections, grounds, injector cleaning and replacement, throttle body cleaning. The works. Could not isolate the -
In this video discussion, I describe the symptoms of hydraulic clutch linkage leaks in 1987-95 Jeep YJ Wrangler models. Originally part of the Q&A Vlog at the magazine, the viewer's question refers to hard shifting and loss of hydraulic fluid. I share what causes these troubles in this how-to HD video on troubleshooting: Moses

I am replacing my oil pump (1998 4.0L), would appreciate any help regarding priming the new pump. I'm a little hesitant to pull the distributor, is there an easy way to do this? Thanks Roger -
My TJ has an occasional cylinder 1 misfire indicated by the check engine light and an occasional lurch at highway speed. I have noticed the misfire when cruising at highway speed after driving about 20 minutes and feeling a sudden lurch, or when sitting at a red light idling. The engine runs fine aside from the occasional lurch and running rough at idle. I suspected a sticky lifter so I ran Sea Foam in the oil for about 2k miles and then changed the oil and filled with 10w-40. I never noticed a misfire on the highway after this, but it idles rough at stop lights and the check engine light -
Been talking about stroking the 242 block I got last year for a while now, but I got tied up with building my XJ and fixing some suspension "over build" (it had 9" of lift) issues with the TJ I bought last summer. Also, got on the idea of a SBC or SBF swap for a while. Now that I've pretty much tapped my "Jeep savings", I'm back to building the extra 4.0L with money being tight for the project. I read in Moses' articles that just adding the 258 crankshaft with a 242 rebuild will also do wonders. Will I really see any reasonable gains or should I just put the money elsewhere instead of gett -
I have a 95 Wrangler with the 2.5L AX-5 combination. I have the opportunity to replace this combo with the 4.2L AX-15. Other then the engine and transmission swap are there any hidden changes that will have to be made for this swap to work? -
I am looking at used jeeps and I will be a first time jeep owner. I am interested in CJs or YJs. I want the jeep mostly for hunting and putt-ing around town. As far as engines go, do you think a 4 cyl would be okay for what I want and not get me in trouble in the mountains, or should I just look at the 6 or an 8 cyl? If a 4 would work, what transmission, axle gearing and tire size would you recommend? I have already found the forums to very informative. Thanks. Rich -
At the magazine, building a Jeep inline 4.0L six with a 4.2L crankshaft (stroker motor) is very popular. Tony Hewes (Hewes Performance, Reno, Nevada) and I did a series of HD videos and shared our favorite components for a 4.6L (0.030" overbore with the 4.2L crankshaft) stroker motor build for combined street and trail use. Since then, we have received a lot of feedback and continue to address the tuning and camshaft requirements of these engines. From our testing, the pre-coil pack (1998 TJ and older 4.0L) engines with older style injectors do very well with Ford 5.0L V-8 24-pound injec

Another pre-forum, Q&A exchange with Jason Logan (forum member JayDLogan) is useful to those installing a new clutch. Jason has concerns about which type of release bearing to use. The discussion continues here at the forum:: Jason: Hello Moses! Hope I am not bombarding you with questions? I have sent to you a photo of two release bearings for my 1999 jeep 4.0L clutch assembly. Both are brand new. Which release bearing should I use? The one on the left is a composite (plastic)/steel design while the other one on the right is full cast (original design) . Thanks for any information
