This build -- Middle-ish of page 5

Well, the above worked until the OBD1 PCM was driven enough for it to ‘learn’… It developed an obnoxious stumble at idle every 6 seconds though ran/ drove flawlessly. (My guess is the late model canister required a purge solenoid, and I didn’t want to deal with it as the PCM triggers a ground that turns it on and off.) Couldn’t live with the stumble so back to the drawing board. I used the original charcoal canister mounted to the rear valance panel with vacuum lines up to the engine bay, and a cut-up front inner fender liner as a splash shield around it. Perfect fit and runs right.

Telescoping steering shafts are available for 84-94 GM columned MJ/XJ’s. It is absolutely no fun installing a new box in these early XJs with the non-telescoping factory shafts. Left to right is a non-telescoping Crown beside an A-Premium (middle) and Dorman (right). The two telescoping shafts have their own unique design. They feel about the same weight and look to be quality parts. Dorman stayed more true to the OE shaft design while the A-Premium sliding shaft is shaped like a +. Would almost think that’s the stronger design. Dorman has good reviews on Amazon and I need to see if there are any on A-Premium. About time the first gen MJs/XJs see some love here.

It was time to free up some workspace around the old 4.0L… oil changes were unnecessarily difficult. Time to relocate the charcoal canister. In mid-1998 Jeep decided to move the XJ’s charcoal canister from the inner engine bay ‘frame rail’ (where our MJ’s is located) to just in front of the rear axle on the exterior floorboard driver side. Pure genius. All ‘98-‘01 XJ’s had this set up. From the early Renix 4.0L days through 1997 the cylindrical charcoal canister was located way too close to the engine oil filter. As equipped from the factory Renix and early HO years weren’t too much of an issue as the oil filter was more or less vertical (spectacularly dumping oil out at every oil change). I’ve always converted early era MJ/XJ’s to the later horizonal oil filter setup for a somewhat less messy oil change. MJ/XJ AW4’s have the trans cooler lines running just below the oil filter in addition to AC lines (R134a ‘94.5-‘96 XJ setup as I’m running have lines wound in a bell shape for flow making the oil filter extremely difficult to loosen with a wrench/ eventually remove), spark plug wires, and heater core hoses (yes, I’m running ‘97+ XJ hoses) cluttering up the entirety of that area. I have barely 3/8” to maneuver the slip-around filter wrench into place. The original setup... And below is the revised setup comprised of an ‘00 XJ canister bracket (installed with a new Standard Motors charcoal box), a cobbled/cut up hard vacuum line from the same wrecked XJ that runs along the frame rail to the firewall, two Renix era engine vacuum harness’ large rubber elbows (Crown Automotive new), the original ’91 MJ horizontal HVAC vacuum line cut and now running vertical from the bottom firewall up to the intake manifold rear-most port, and a ‘97+ XJ air box/ lid (at right in pic below). Other doo-dad’s include a new freshly bent 1/4” brake line taking whatever vapors that exit the two roll-over valves at the top of the MJ fuel tank into the charcoal canister and a ‘98-early ‘99 TJ canister breather ‘top hat’. (The TJ had an almost identical rectangular canister to the later era XJ with a different bracket. The difference TJ to XJ is that the ‘98 XJ instead of the ‘top hat’ ran this breather line up the frame rail up to the lower center area of the firewall where it just stopped and connected to absolutely nothing. ‘99+ XJ’s saw that breather line connected to an even more convoluted emissions venting system.) An alternative to this TJ cap would be a simple breather line into the MJ frame rail. The end result is a ton of space around the oil filter. I can actually get a whole hand and arm in there. Perfecto. (Worth mentioning in this writeup, both my MJ’s are running an exhaust turn-down pipe just after the muffler. The exhaust doesn't go all the way back. But based on the trajectory of the muffler it looks like running this setup with the stock MJ exhaust wouldn’t be an issue.)

In addition to what you have noticed, you'll also want to POR15 the entire floorboard. The seams aren't fully sealed. Rainy season water can also come up from between the floor panels and seat track mounting studs. When you POR15 it, you'll get to see all the less than sealed spots. Worth doing before putting the interior back in.

I’ve been holding my breath for the past 5 years hoping the measurements and work I did on the support bracket between the front crossmember and bumper was spot on for my hidden winch setup. And thankfully it was – just bolted it all together. My youngest helped me with this whole hidden winch setup back when she was in 4th grade (and she starts her freshman year of college in a few weeks). Crazy how time flies – and how long sometimes these projects take to get done! The go-between support bracket itself has weld nuts just behind the front bumper for the fairlead and Maximus winch line hanger bolts to thread into. Nothing is bolted down tight but wanted to do a test fit before taking everything to get powder-coated. Mounting hardware for the fairlead will be the same stainless steel bolts I used on for the factory sport bar. There will also be a ‘dust brush’ (shown below) just behind front bumper to keep the winch line clean and bug-free. Warn Epic fairlead and hook both blacked out will adorn the front. Getting back to it!

She's my daily. 88K on the clock now. Bought it at 85K.

Got around to cleaning up and painting the MJ-specific SnugTop I found a while back. Decided satin black was the way to go to keep the Chief graphics poppin'. Next up... rebuilding and gearing the D44.

Looks like the aftermarket is modifying 97+ XJ style evaporators to work with the slightly older setup with threaded nuts. There was no difference in the AC HVAC box HO years r12 to r134. I see though why you need to modify.

Seems like you're on the right track... Just know you're going to want to keep it to the renix years (87-90) as this is where you started from a pulling parts perspective. 91 was a different set up; '94.5 year-'96 got r134.

Looks sharp. Like the rims also. Era appropriate.

I've wondered about that also -- the only thing that came to mind was maybe a potential diesel variant in some other market?? Hard to say as that clock shape is unique to MJ/ XJ only.

At first I thought this was an R/C MJ, as the flares are kinda nuts... But I see these taillights are available on both Etsy and eBay. Not so much a fan of the American flag version, but having the flexibility of including amber (especially for European MJs where it's required at the rear) is nice. Good first effort on this. I don't think the lenses look quite right yet, but different. And not sure what the little turquoise piece is for. Possibly locks it all together? I've never been a fan of the 3 section factory taillights; always thought a smoother design would have looked better on the MJ. https://www.etsy.com/listing/4521337669/jeep-comanche-mj-taillights?gpla=1&gao=1&&utm_source=google&utm_medium=cpc&utm_campaign=shopping_us_-electronics_and_accessories&utm_custom1=_k_Cj0KCQjwornRBhCrARIsAON5exF-mKh0CTGcAtxvi8vty8SPhAFOb1cPe8k6as2unxzM97M4QIIFppgaAjyOEALw_wcB_k_&utm_content=go_21500569338_164907277163_707558291657_aud-2545588685997:pla-315906365651_c__4521337669_12768591&utm_custom2=21500569338&gad_source=1&gad_campaignid=21500569338&gbraid=0AAAAADtcfRLj7PteAPUDdUbbRjBQcpQ9O&gclid=Cj0KCQjwornRBhCrARIsAON5exF-mKh0CTGcAtxvi8vty8SPhAFOb1cPe8k6as2unxzM97M4QIIFppgaAjyOEALw_wcB

Jeep did it a couple different ways over the years. As mentioned, a blank cover attached to the dashboard overlay and also, but less common a full pod that was screwed in (similar to the at left fog/ cargo light pod) but with an adhesive blank cover (this was more commonly found on Renix era plain Jane XJs).

There was a car show in town recently, so I set out to get the name of a good powder coat shop. I had gotten lots of thumbs-up on an in-town shop over the past year, but the guys whose restorations were top notch at this show universally said – don’t go there, go to Outlaw powder coating (little ways away). And so it is. The MJ’s bumpers will be dropped off this week. I decided that the factory black trim taillights just didn’t look right with my graphics. Majority of the lines on the lights are vertical while my graphic breaks are vertical. Going with solid red lights. Also, with the MJ having a clear theme of silver and black, I’m thinking there is a good chance I’m going to run Marchal black fog light covers over the white. Will see. Just finished polishing the custom Buick GNX billet center cap sleeves (difference before to after) and then will modify the Nissan Titan center cap to fit atop the sleeve and finish it off with a domed logo’d ‘Jeep’ emblem. Instead of a having white logo, I went with silver & black to keep with the theme. Lastly, the alternate grille is just about ready for paint. Finished it off with 1000 grit this morning/ ready for black trim paint. I think the grille to go with will be a modified all black setup. Got the screw inserts back side permapoxied into place and flat top screws will be used to fasten the mesh insert into place.
