  1. My truck is an 89 with 2.5L and 4spd. I bought it a little over a year ago for $400 and have been tinkering on it since. When i got the truck it was basicly stock other then the 31x10.5 15s, the lights on the sides of the cowl which were cosmetic and had never been wired in , and a flowmaster muffler,it ran and drove but had been neglected/abused and needed ALOT of little things. First upgrade i did was a guage swap,my truck is a base model with idiot lights so i swapped them out for guages from a 1990 XJ. No photos but I'm sure youve seen MJ/XJ guages next project was the
  2. I purchased the Comanche from the 2nd owner who did nothing to and it sat for at least 7 years. I purchased it because I love Comanches. It was gonna be my toy. Then reality set in and and I remembered that I have 4 kids. It sits more then I driver it.. Runs and drives great. I Have done a ton of things to it because it sat for so long I wanted to make sure it all worked. A couple of things that need to happen Oil Pan gasket needs replaced(I have the gasket), Timing cover gasket (I have the gasket). I was going to do the head gasket (have the gasket), I planned on doing the exhaust manifold g
  3. Quick question (hopefully). Putting a new power steering pump in my 90 Comanche, 2.5l. When I disconnected the old PS pump high pressure line (top finger) this is what it looked like. New pump looks like bottom finger. I assuming i just need to take the nipple with the o-ring off the old high pressure line, then that long cylinder before the bigger nut will go in the pump, right? Any help is appreciated! Thanks
  4. This is my first attempt at completely rebuilding/restoring a vehicle. I have no previous mechanic experience. I was curious if anyone would give me some advice on the process. What needs to be done first? I have drained most of the fluids. Removing the gas tank is next. But after that, do I just clear everything out underneath the hood? How do I check to see if I need to replace my engine (supposedly it has a cracked head gasket; and if its not terrible I should be able to replace it, correct?). I am open to any suggestions. I am flying blind on this one. I have checked YouTube for help, and
  5. Oh yeah burnt the hell out of that throw out bearing. Wouldn't you know it, I was on my way to work. Yep custom intake and open up air flow I, someone else on CC has done similiar using a speaker mesh to cover as to mine is just open. Attempted to do CAD flip but needed to jack up truck to aline 2 piece shaft for colar to slide over. Someone elses photo on CC but just to show what it looked like before I closed it up. Oh that's my clutch pedal and clutch master push rod linkage Cleaned up both
  6. Well, I guess this is the start to my build thread! won't really be a build just the progress of my daily. I’ve had her for like 2 months now and so far ive: Replaced both window regulators Fixed a lower radiator hose leak Got a steal on new taillights Did front breaks New tires Window tint Right now I'm working on chasing down a TCU problem. My trans isnt shifting on its own so I have to go 1-3-4. I’ve got some big plans for this truck in the future its just a matter of saving up! If you want to follow the build closer follo
  7. I have only been on this site for a little bit and haven't posted enough things to create a classified listing yet, but I am looking to convert to the aluminum cover for my 2.5L. I don't have many options for junkyards around here and haven't found a suitable donor yet and am wondering if anyone has one they can part with or can point me in the right direction to find one. I've seen for the gasket to use a FelPro vs50502r and a cover from a 93- YJ or a Dakota with a 2.5. I haven't been able to locate any of those valve covers online anywhere either though.
  8. I am about to head to parts store to grab some bulk hose to do heater control valve delete and wanted to know if the hose I am pointing to at in picture needs replumbed. It seems to run from thermostat housing into front of Intake manifold and right out the back of Intake manifold and into heater control valve.
  9. Hello guys, hope everyone is doing well! My motor is on the way out, I check the engine compression and three cylinders are at 90 psi and idling rough . thought about rebuilding but going with remanufacture instead, what are you guys thoughts on ATK and sure fire engines ? I heard really bad reviews and what do you guys recommend ? (still wanted to keep small 4 cyclinder instead going 4.0 ) The MJ is my daily driver, details in my MJ are 1987 base 4x2 2.5 L Thanks for the reply !
  10. For those of us that still love our 4 screaming squirrels, here is a little necessary upgrade/Egr Delete The manifold I used was from a 2.5l yj ( a knock off pacesetter header from ebay) Header Link and EGR Block off plate There are going to have to be some modifications, the new mid pipe is shorter than the original, so you can either lengthen your new mid pipe or lengthen youe existing exhaust set up if you are going to reuse it It is short about 1-1.5 ft, so it gives you the opportunity to run a new exhaust if you want
  11. Hey guys, as some of you may know my oil pressure sending unit fitting broke flush with the block and this is a write up on how to get it out. Yes there are several ways to get this fitting out, such as pulling the engine, removing the engine mount etc. This is what worked for me and can be used as a reference for other 2.5l renix owners. This problem started when I swapped my cluster from the dummy lights to a full cluster. The oil pressure switch ( which turns on the dummy light if oil pressure goes down) does not work with the full cluster. I got the oil pressure se
  12. Hey guys I was wrenching on the jepp today and nothing good happened. The plan was to go in and remove the oil pressure light switch in favor of the oil pressure sending unit I have for the gauge to read properly. As I was trying to take the old one out *SNAP* the 90° brass fitting snapped at the block. I am trying to figure out what to do. I have tried an extractor bit but the drill doesnt fit the the space and the engine mount is in the way. I will post up pics soon
  13. I tried searching for the answer to this, but I've had no luck. I tried starting my truck today, and it wouldn't start. So I opened the hood, and noticed gasoline sprayed around the passenger side firewall area. I'm at work right now, so i havn't had a chance to really check it out. Does anyone have any clue what could be going on? If any of you have seen my build thread, you probably read that the PO put gasoline in the master cylinder. So I'm terrified about what else he did.
  14. Just curious, what is the group consensus on painting the grill/headlight surrounds to match body color? Like how Zone Offroad did with their comanche. Personally, I think it looks great. Kinda afraid to do it though, because I love the classic look. Although, my truck already has the wrong grill. It's an ugly chrome now, and I very much dislike chrome. I guess worst case, I could paint it black if I ended up not liking it. thoughts/comments? ps. here is a picture of the Zone truck because I know everyone hates threads without pictures. lol
  15. Let me apologize in advance if this thread is in the wrong place. I bought a toolbox for the comanche. Unfortunately it has no key, so i have no way to lock it. Has anyone ever replaced the locking mechanism on a toolbox? Is it fairly simple? I won't be keeping anything valuable in there, so if this is going to be a huge PITA, I will just live with not being able to lock it. It would be nice to not have to worry about someone stealing my jumper cables or gas can though.
  16. I'm new to the site and recently picked up an 86 2.5L with a 5 speed and 4.10 gears. I know its a 4cyl but it just doesn't have the power to make it up some of the hills in town anywhere close to the speed limit. Are there any upgrades (other then motor swaps) that will increase the power and performance? Right now it is fully stock, but I'm planning on putting on a 3" lift and 31s before the winter starts here. I have heard about throttle body swaps and different injectors, but i don't know where to start. Any help would be appreciated.
  17. I have a 1989 Comanche sport truck. It is a 2.5l 4cyl 2wd. I am in the current process or rebuilding the engine and doing a 4wd swap. I have pulled the ax4 as it is worn out with nearly 350,000 miles on it and intend to replace it with a Ax5/np231 combination. I have sourced a pair from a 97 2.5l TJ. Will that bolt up to my '89 block once i get done rebuilding my engine? and is there any serious modification required to do that swap? Any extra electronics on the '97?
  18. Looks like this guy has had a hard life, someone should save him: http://www.govplanet.com/jsp/s/item/666840?h=345-22,15471 2.5L 4x4, 1986 Model with 160k on the clock. Probably none of that was highway miles either. But, the auction starts at only $900!
  19. So the belts on my 86 Mj are dry-rotted, and I'm in need of some new ones. Problem is, I have too many options. Unfortunately I'm using my phone at the moment so I have no way to upload pictures, but I need the one that has the grooves in it, I belive it's called the v belt. I'm probably wrong on that though. I also need the smooth one. Rockauto has belts for my truck, but some day with ac, others say without and I don't know which ones I need. My truck does have factory ac, power steering, etc. Problem is, I don't know which belt is supposed to power what. Any help?
  20. Hey, so i just picked up my first Comanche, its a 1987 4x4 2.5L 5 spd. sporTruck in red. It's a project to say the least, but I'm excited none the less. I'm pretty mechanically inclined and have all the tools and access to most of the machines to do most of what I need to, only major problems being: 1: Funds 2: Minor access to heated building to work on it in the frigid Illinois weather as my garage is not heated and my dads garage has two cars in the front heated garage and 3 cars in the heated shop in the back yard :fs1: he has more projects than me I think It has a few issues th
  21. Merry Christmas everyone! Quick question about the fan/fan clutch. I finally got her running so now its time to buy the parts I'm missing to get her driveable. My question is, on my 86 mj, the pulley for the fan clutch only has one stud coming out of it. is that normal, if not, can it be fixed, or do I need a new one? I'm trying to post a picture but photobucket isn't working for me at the moment.
  22. Hi guys havent been on here in a while but its summer now and work on the truck begins once more. So ever since I have had the truck it has run rough. It has gotten rougher and rougher over the years. Its at the point where it won't start without some gas and then it won't remain at idle without gas. After it has warmed up itll idle okay, but still pretty rough.' So i took it to a basic auto shop to check it out. They found that one of the cylinders compressions is at around 25lbs which is what they said was low comparable to what they said it should be like all the other 3 is 150l
  23. Ok,so I'm very new to Comanches. So new in fact, I had no idea what they were up until a couple months ago when I was forwarded a post of one for sale. Well I bought it and I love it. I think it would be very cool to convert it to 4wd and from what I could figure out, that should be as easy as finding a doner cherokee and switch the trans and axles. Then I know upgrading to the 4.0 would be really cool as well. Unfortunately that's a much larger job than I could do on my own and since this is my daily driver, I can't be without it too long. I guess what I'm looking for is some quick and fun mo
  24. here we go again 86 jeep comanche 93 jeep cherokee 2.5l engine low idle runs good when cold as the idle drops to normal begins to misfire and it gets worse the warmer it gets to the point it dies and starts itself again.... driving down the road at a low rpm runs fine put any type of pressure on the pedal to accelerate it begins to buck and misfire terrible....... drove to work today stopped to turn and the truck died went to start it, and had to hold my foot to the floor to get it to start.... seems like it lacks fuel but pump sending unit resistor and pressure regulator are brand new. i pull
  25. Went to the junkyard today with my sights on getting a Durango steering box and brake master cylinder for my XJ. There were a ton of Durangos and Dakotas out there. When I'm there, I always check the Dakotas for the infamous AMC 2.5L and 5-speed. Sure enough, the last one I checked, a '98, had the engine removed but the 5-speed was still there and still intact. I jumped into the engine bay and snatched her up. Can't believe I found one after all this time of searching... With that said, I have no use for it at the moment since I did the 4.0 swap... If I could've found this last year, I w
