Yes, they used the Iron Duke for a few years in the late 70's, I believe. They dropped it when they came out with our own, dearly beloved 2.5L I-4. I think the Iron Duke was used in some years of the Concord and the Eagle. Yup, the iron duck could be found in most any amc as well as the CJ's.

I don't know of any plastic 4.0 valve covers?

Just got my new Asus Eee PC today. 10 inch screen, 160 gig hard drive. 7 hr battery. Good so far. Screen is incredibly sharp and clear. Keyboard has a very good feel to it as well.

OK, give me a list of non AMC engines used in Jeeps during the AMC ownership.

Hmmmmm, I think I know a little something about AMC engines as well. You are not the only well aged guy here. :chillin: . And I agree about the blasphemy!

Congrats and welcome. Let me be the first to let ya know that Comanche only has one 'M' :D . Enjoy your truck. I'm only on my second, but some guys here have a serious addiction going.

Have seen this a couple of times, but it was always the hose from the sender to the pump and you said you already checked that. Is is a quick turn that does it, or a long slow one? If it is a quicker turn, it may not be fuel at all. Check for a harness rubbed through somewhere.

Are you sure it is the cap?

I hand this out in class: TECH 101 – source Bubba Engineering Limited Page 1 of 3 Here are some interesting new tests developed by some of our brightest engineers with strange nicknames using probable value /observation equation technique. Use them carefully. FUEL PRESSURE CHART (For those who refuse to use a pressure gauge) Due to the fact that most technicians do not want to take the time to correctly test the fuel pressure, we have developed the following... With the engine running, either push the Schrader valve in or loosen the fuel line THEN IF: Observation Probable Value (PSI) Fuel does not come out of the test area Approx. 0 Fuel hits the hood insulation 5 - 8 Fuel squirts over the fender 10 - 15 Fuel splashes off the fender onto the hood insulation and into the next repair bay 25 - 30 Fuel squirts to the garage roof, all over the car and hits shop owner or mgr. 35 - 50 VACUUM TEST "The Rule of Thumb" Put thumb on vacuum hose leading to direct vacuum Observation Probable Value Don't feel anything Change thumb and retest Still don't feel anything Vacuum is very low to none Hose has slight suction 1" - 5" Suction causes skin to wrinkle 5" - 8" Suction turns thumb blue 8" - 10" Suction creates hickey on thumb 0" - 12" Suction creates pain 8" - 20" Suction will not release and begin to move toward index finger 20 - 25" TECH 101 – source Bubba Engineering Limited Page 2 of 3 TEST LIGHT ILLUMINATION CHART With the vehicle prepped and ready to be tested, hook the negative lead of the test light to a good ground and proceed with testing. Observation Probable Value (Volts) The bulb DOES NOT light 0 – 1 The bulb MIGHT be glowing 1 – 3 The bulb BARELY GLOWS (or there is a reflection from the overhead lights) 3 – 5 The bulb GLOWS MUCH BRIGHTER than #2, but only a little brighter than #3 5 – 7 The bulb GLOWS WITH THE SAME INTENSITY AS A BALD HEAD ON A SUNNY DAY 7 – 9 The bulb GLOWS BRIGHTLY and is GAINING IN INTENSITY 9 – 11 The bulb is ALMOST BRIGHT ENOUGH TO READ BY 11 – 13 The bulb is BRIGHT ENOUGH that you still see a spot when you look away 13 – 15 The bulb SHINES WITH THE INTENSITY OF A HALOGEN HEADLAMP 15 – 17 The bulb is so bright that it MAY BE A SIGN FROM GOD 17 = 19 The bulb flashed with the INTENSITY OF A MINOLTA FLASH POINTED 3 FEET FROM YOUR FACE 20 - 20,000 Note: may be testing coil pack IGNITION VOLTAGE OUTPUT TEST Scopes may be inaccessible from time to time, so here is a test for Ignition Output : 1. Hold medium wrench in one hand. Sears wrench preferred for accuracy of test because other smooth wrenches are too slick for throwing. 2. With the engine running, grab hold of the plug end of an ignition cable and with the other hand, hold on tight! 3. Pull plug wire. This will more than likely cause you to throw the wrench. KV output is based on how far the wrench was thrown. NOTE: Experienced users have learned to move other vehicles aside while conducting this test. Observation Probable Value (Volts) +10 feet 10,000 give or take a few KV +20 feet 20,000 give or take a few KV +30 feet 30,000 give or take a few KV +40 feet and beyond 40,000+ (add a couple of 10 KV as needed) Caution! Must be one of them new ultra high output ignition systems, next time use a bigger wrench. TECH 101 – source Bubba Engineering Limited Page 3 of 3 HOW TO TORQUE WITH AN IMPACT WRENCH With a skilled ear and quick finger, you can use your impact gun to torque nuts and bolts. Please note these values are for Ingersol-Rand brand impact guns only! Probable Value Observation 25 to 35 ft/lbs BAP! 35 to 45 ft/lbs BAP! BAP! 45 to 60 ft/lbs BAP! BAP! BAP! 60 to 75 ft/lbs BAP! BAP! BAP! BAP! 75 to 90 ft/lbs BAP! BAP! BAP! BAP! BAP! 110 to 300 ft/lbs BAP !BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! BAP! Stripped/broken bolt/nut BAP! BAP! BAP! BAP! BAP! BAP! VRRRRRRRRRRRRRRRRRRRRRR! Crap!

You don't need a hole that big either. Just enought to get to the bolts with 1/4 " drive socket, then slide the whole thing toward the engine compartment. Remount the new one further back, like where it will cool better when it gets hot. Geniuses, these engineers, huh?

I personally like the little 2.8. It really gets better with MPI, but that is a lot of work. A different carb would be a great upgrade. The varijet on it now is the absolute worst carb I have ever worked on. I think the issue with the engines self destructing is that GM sold AMC a bunch of substandard engines, just like they did with the iron duke 2.5.

Not sure if I used the correct terminology in my post. I am trying to find the information on this. I remember learning about it in a class a LONG time ago. We were basically told that it can be used to check the mix level of the coolant.

Your coolant will actually produce a voltage based on the electrolytic reaction in the system. I highly doubt that that is what caused your new radiator to leak. It is present in all coolant. Where is the new radiator leaking from?

I just changed the bulb in mine. It was just a couple of bucks for a pair at Advance Auto.

Pete, do you have a pull over as well? I have a pull over in XL and it fits fine. I like my clothes big, just not rapper big :D

Don't know which way to go on this one. Haven't had the chance to see them side by side. Until your link most of the 10 inchers were a 100 more than the 8.9's so I didn't see the benefit, but only 50 or so more might swing me. Thanks for the web link, I'll check that out before I buy. Another reason I'm interested is as a work thing for tech's. The newest Chrysler scan tool needs a laptop in the car to view data. Something this size would be a much better set up for a tech than a full size unit. Hey dasbulliwagon, you guys have your Witech up and running yet?

Ya got 4 0r 5 401's to go along with them? :brows:

Is xxl the only size you have? I'm in for one if you have an XL. Thanks, Joe

Well, I don't play games and don't mind having an external drive for rare occaisions. Just like the idea of the portability. And the price for the 8.9 inchers seems to be around three bills. Have you guys used it with a remote monitor?

:nuts: Put down the crack pipe and slowly back away. :D (see the smiley).The 2.8 is in his Comanche, not the J truck.

Bring a camera with you!!!!!!!

never seen a HP ZJ.

I guess the only thing bothering me in this whole thread is how what Sam posted could be taken as anything BUT a joke. :dunno:

Brent, I hope you realize that I have a great deal of respect for you and think you are a hell of a good guy. But please understand that your cultural thinking is not universal. Dogs and cats ARE food for some societies. I grew up in a failry impoverished (though we didn't know it) area of NYS on a small farm. All I was saying is that rabbits were not kept as pets. Many raised some type of rabbits, I have no idea what they were. I raised several pigs and calves for 4H. Some even followed me around like a dog. Eventually they met their end as part of the food chain. This does not make me ignorant or uneducated. I never in any way insinuated that YOUR rabbits would or should be food. I think what you do for the rehabilitation of these animals is commendable.

Don't know if it makes a difference or not, but some of those ZJ's had something called Speedpro steering. It was a module that changed the amount of assist through the pump.
