    Glass - Oooops.

    Broke out a back hatch glass or side window? It happens. Is it hard to fix? Not really. Side or back, it's held in with a rubber gasket. The gasket has two slots, one for the glass on the outer side, one for the body flange inside. You probably discovered that pulling the somewhat empty gasket...

    Projected nose plugs in the RENIX

    Looking for some input from knowledgeable spark pluggers - A regular plug for a 90 RENIX is a NGK FR5 (7373.) Hohum, runs ok does the job. For the 92 its a projected nose design FR5-1 (7252) which is also what the 2.5 uses. The projected nose is .200" longer after surveying Autolite and...

    30 degree valve seats

    A coworker has been a fountain of info lately, and showed me his copy of Dave Vizard's third book on Chevy engine building - specifically, 30 degree valve seats and how they produce more hp at low lifts with mild cams. I nodded my head and answered yes to stuff like "you know how hydraulic...

    Improving the Renix crank time

    If you have a Renix XJ, you know about the cranking the system requires to get a signal before it will start. For some, this seems to be a lot longer than it should. The RENIX computer has to see 300 RPM for a few cycles to pick up a valid signal from the sensors, so it seems. Try the following...

    Those guys at the auto parts store . . .(long)

    Many of you buy parts at parts houses, and I'm sure you have favorites. The industry is consolidating a lot now, there are fewer independents and bigger chains every day. I work at one of them, and have for another. We all pretty much know what we own - XJ's. That can still be a challenge, as...

    MSD Spitfire Ignition

    It's been out for a year. Has anyone installed one, and does anyone have an opinion? CD ignitions aren't the highest priority on our modding list - but some of us have XJ's getting long in the tooth. Blowby, oil consumption, and fading power over the years takes it's toll on our enjoyment -...

    97 to Renix taillight swap?

    Searched here & googled. Where do I remember a post about the 97 up to Renix taillight swap? It definitely required reshaping the deck lid a lot more than the swap. Some may disagree, but I like the looks of the later model taillights. It seems to me to be a matter of making the tailgate fit...

    Watch those replacement fan drives

    Hit a deer last night. Now my 3 core GDI is terminal. What took it out wasn't the fan or the deer, but the fan clutch. It's a replacement with five cast fins that stick out directly toward the core 3/4". The impact pushed the spinning fins into the tubes and severed them for a 6 inch arc...

    Massively loud lifters - and a cure

    Ran into a problem a few months back - the lifters collapsed and began the "Death Rattle That Sounds Like a Diesel Truck." Searched and found a cure - frequent oil changes and Marvel Mystery Oil, which seemed to work. But it came back, even worse. Change oil again. More MMO. It came back...

    Dirt simple horn repair

    Hi, my name is Tirod (ahem,) and I own an XJ that hasn't honked in two years. I've changed everything out, the horn button, slip ring, turn signal and harness, and the ignition switch on the bottom of the column. I jumpered the horn relay contacts with a push button to get some action, but...

    Hella upgrade w/ wiring harness

    Put me down as another happy camper on this upgrade. For those of you who cringe at the idea of any electrical mod beyond battery cables, you should really take a deep breath and reconsider. 1) read the Gojeep tutorial. Print it out and convert everything to inches. Maybe some day metric will...

    battery bus bars

    No, not hi test martinis on a commuter vehicle. I just finished installing a headlight relay harness and E-codes. Love the light. Thanks, Gojeep, your instructions are great. I don't like the ring terminals all over the battery posts, tho (not your fault.) They are electrically sound, but the...

    2009 Jeep Cherokee diesel

    AP - The new 2009 Jeep Cherokee will come with a clean diesel engine to help improve fuel mileage . . . I'm paraphrasing the article I just read, mostly on the new V-6 that can run on three, but am I late to this news?

    $50 paint job

    Searched some and don't see it here, so if it is please correct me and link - A Corvair enthusiast and others are using a new/old school method of painting with Rustoleum, hard foam rollers and multiple sandings. It seems the total outlay is in the $50 dollar range, and from the slick looks...

    Spooled front diff - anybody drove one?

    Anybody with experience driving a spooled front diff XJ? Handling, tire wear, or breakage issues? Looking for the general how it worked for you, off road or on - if on pavement, did you have an axle disconnect or hubs? This is part two of finding out if its doable -

    Locking a front disco axle -

    Welding, spooling, or whatever - for a disco Dana front 30, what specific problems will crop up locking the differential? On pavement, disco open, axles allowed to differentiate; of course, you gotta do that. Off road, in 4H/L, axles locked. Full time traction. I'm talking snow, gravel, mud...

    engine balancing - really?

    I've been reading and working on auto mods since I bought a '66 Mustang in the early '70's - now I have a '90 XJ, which is a lot more similar than I would have first thought (inline six, unibody, aging electrics, etc.) Every engine buildup I have read or done included engine balancing - getting...

    engine bay reinforcement

    Anyone seen a "shock tower" cross brace for the XJ? I keep looking at an engine bay built like a 66 Mustang - and Shelby added a brace to stiffen it. There was already one on bottom - the XJ doesn't have any. If the steering box will rip out and needs braced, and a winch bumper is alleged to...

    Horn blows and shorts out the fan?!?

    Well, not exactly, but I need help. This is the second time - I fixed it somehow before . . . Laying on the horn caused a Zrbrt noise in or below the dash - the horn didn't honk - and the next time I checked the temp gauge by golly the fan wasn't doing it's job. Popped the hood, tapped the...

    Single (electric) disconnect swaybar?

    I have searched and found more crack smoke than what I'm looking for, but haven't I seen or read about an electric disconnect swaybar? It had a solenoid operated spline coupler centered on a tubular "bar" and operated by a switch on the dash. Yeah, I do live in the 417 area code, no, I am not...
