Rev's '88 Comanche build

I sold my XJ back around May, and I had been looking for an MJ before I ended up getting my XJ. So before I put more money into the XJ I felt it was best to move on. Well after all that time I ended up hauling a truck back today with a friend. We drove about 2 hours out for me to get this one, it's a 1988 4.0L, 5 speed, D30/D35, Sportruck with 94,453 miles. The previous owner parked it roughly 10 years ago due to a bad alternator, he said about 6 months later when he went to replace it he noticed some of the engine harness had been chewed up and shut the hood. After intending to fix this up for his now 13 year old to drive he decided to sell it to help with bills and let it stop 'rotting.' It's in great shape, there are very few dents or dings and NO rust from what I've found. I can't WAIT to get this back on the road and ready to enjoy!









It's amazing what a pressure washer will do.













I plan on tuning it up and flushing all the fluids this weekend. I'll be scouring the junkyard for a renix 4.0/5speed engine harness to probably just swap it completely out.


Here's my old XJ.

Dropped $300 on parts so far today...lol Ordered a new alternator that should be in Friday, went from a stock 65amp to a stock upgrade 105amp. Got all fluids for radiator, engine, diffs, trans, transfercase, and a bottle of Marvel Mystery Oil I plan on putting in the cylinders today to help lubricate them before I do an oil change this weekend. Got a water pump, thermostat, all heater/radiator hoses, all new ignition tune up parts, filters, and went ahead and got a new serpentine belt. I'm kind of bummed I don't get off until after dark or I'd get more done this week. I'm thinking of taking a half day on Friday since we're having our holiday party, that way I can tear out early and start working on it!

Aside from the harness it looks to be in great shape. Have you pulled up the carpet on the driver floorboard to check for rust? Also check the fuse box to see if the clutch master cylinder has leaked and damaged it. Those are the two main issues most people find on the MJs. Good luck. Nice to have another MJ owner in ATL.

Thanks man! I didn't pull the vinyl flooring to inspect that area for rust, but I did check the fuse block and that was fine. Since there isn't any padding on the backside of the vinyl I didn't bother inspecting because I figured it would be obvious. But honestly I was bringing this truck home regardless of a little bit of rust. haha

Make sure you watch your eng. temp. If you get hot you're losing pressure in that old overflow tank. It has to hold 16lbs of pressure. Don't ask, Autoparts stores don't carry them, salvage yards are ghost towns, and Chrysler Jeep will laugh and say AMC made those. No remakes. But you can update your coolant system to a '91 style. Bypass the overflow tank, get a new radiator with cap, and just an unpressurized overflow tank with vent tube, you can mount it behind the radiator on the drivers side. $100 fix at most.

You can get the expansion tank from partsgeek. http://www.partsgeek.com/catalog/198...sion_tank.html

Thanks for the input! I've already purchased a Spectra ''conversion'' radiator with a cap and the temp sensor plug in the side of the radiator. I'll just source a reservoir bottle and swap it in! The weather has been terrible here so I unfortunately haven't gotten the chance to really get anything done. The harness is wrapped up though, so that should just be a matter of installing it!

Well my big hold up at this point is my harness. Everything else is practically done other than flushing the trans and diffs. The waterpump, thermostat, alternator, and belt are in. I've got the radiator in place but not installed as it's going to make fishing a harness back in a good deal easier. If I can find a harness this thing should be running with about 2 hours worth of work!





I can't wait to drive this thing!

Thanks!

Non CAD HP30 with 30 spline unit bearings (already have the stubs and unit bearings)
Ford 8.8 rear SOA swap (going to look for disc rear, lsd, 4.10)
Long arms
97+ front and door conversion
Eventually an ax15 swap

Otherwise I just want it to be a clean driver/weekend toy.

No luck on a replacement harness just yet, I've found a few RENIX era 4.0/5 speed harnesses but they all have additional relays and are routed differently.

Buuuuuuuuuut, I did just make a sweet score.

Made some headway on my old chewed up harness. I also got a clutch fork, seal kit, throwout bearing, and the CJ 304 pilot bushing for the ax15. Hopefully this harness will work out once I have it back in there. If that gets me on the road I plan to source the rest of the items for the ax15 swap, that'll be the first be project before a lift or axle swaps.







The missing section was cut from an incorrect harness so the coloring would all appear as factory as possible.
