This may be kinda long, but I want to give as many details as possible..... 87 Laredo 4.0L AW4 NP242 Anyways, few weeks back the jeep began sputtering very badly after it seemed to warm up. I figured it was a fuel filter/distributor cap issue so I replaced both one night. Started up fine the...

I have seen the schematics to make a variable MAP sensor on Dino's page, my question, will this same mod work with the Renix system?

Can anyone who may have carfax please look up this VIN number for me? I would really appreciate it! JM1NA3533S0605964

Hey guys I have an 87 Laredo and I need a full weather stripping kit. The jeep is originally from Denver with dry weather so everything has cracked/rotted on it. I'm not just talking weather stripping around the door, I need that and around all the windows including the hatch glass side...

Hey guys, I have an 87 XJ and I am having a problem with the A/C. I recently charged it with R-12 so it blows nice and cold, but when it cycles (when it turns off for a small amount of time, then comes back) it stays off for a LONG time! I used a multimeter on it to see how much voltage it is...

Hey guys, I just need a confirmation that any aftermarket header that can fit the HO engine is still compatible with the Renix system. Isn't that true since the only real difference in head design is the location and porting of the intake ports? The exhaust will still be the same, right?

Hey guys, I searched around and didn't find a definite answer if anyone has attempted or knows anyone who runs this on their Jeep. It's cheap enough and I am considering putting it on my 87 to see how it works out. Why? Cause I'm bored and would like learn how to do it! Would you expect any...

For those of you who have the A-pillar gauge pods, where did you get them? I found a place that sell an autometer pod but it says its only from 88-00 Cherokees. I have an 87 but I can't believe there is ANY difference...

Hey guys, I have an 87 Laredo that I just rebuilt back to stock specs except I put in the Crane Cams 753901 in it. I knew I would lose some low end power, but now the whole car just seems slower than it was before. What can I do to regain some low end torque, or atleast make the car seem faster...

I saw this at the stillen website http://www.stillen.com/Supertrucks_detail.asp?cat=2&subcat=286&Brand=&id=33214&page=1 and wondered if anyone had it, or their views on it.

Has anyone swapped newer grand cherokee seats into their XJ? I ask this because I would kill for heated seats and I feel that if they fit correctly I could make a switch for it to work in my XJ. Any ideas?

Hey guys, I have an 87 Laredo with the Jensen Premium audio system. After looking through a Chiltons wiring manual I found that not only do I have speakers in the front doors and the rear hatch, but 2 speakers in the lower part of the dash (I always wondered why there was little grills there...

Hey guys i need to change my tranny fluid and it will be my 1st time doing it. I know I need dexron/mercon III, but I wanted to know if there is any precautions I need to take to change out the filter and filling the system back up. Thanks!

Hey guys, I have an 87 Laredo with the Dana 44, and I wondered what are my options on converting to disc brakes? What parts can I pull from a salvage yard in order to do this and how much do you think is involved in undertaking a project like this? I am a college student that can work on...

Hey guys, I have rebuilt my 4.0 and have put it back in the car but have not fired it up yet. Anyway, I was double checking everything and I found this tube on the left side of the bellhousing (if you look at the engine from the grill, its on the left) and I put tape over it so obviously nothing...

Hey guys, first off, I have an 87 XJ with the AW4 and a D44. The car has 181k on it is in need of a little help. I am rebuilding the engine as we speak and I am waiting to make the final adjustments...Anyway, before I did anything, I noticed a strange thing (perhaps problem?) about leaving the...

Hey guys, I am thinking of building a budget stroker like Dr Dyno, but haven't heard of many people using the Renix engine as a base. I called a Jeep shop and asked a couple of questions but I don't think the guy knew what he was talking about. He said you can't build a stroker with the older...

Hey guys, you may have noticed I have been posting questions about the 753901 cam and other things on my rebuilt 87. Well, we have been having problems with it so we took the head off to see if I bent a valve. Well, to make a long story short, the cam has eaten the lifters (all of them but...

Hey guys, I am having the crappiest day ever. I have been having problems with my rebuilt 4.0 I recently re-installed in the Jeep. So far it hasn't been anything major until yesterday. To cut right to the chase, I purchased the Crane Cams 753901 with the recommended anti-pump up lifters and...

Hey guys, i got my new engine in and it runs, but i know it is not completely filled with coolant. Since the engine is brand new with 0 miles on it, it kinda runs warm because of all the new friction. When the engine gets warm and starts to build pressure and overflow from the catch can, when...
