So I picked up a 2004 XJ 4.0 engine and didn't realize the many differences in the block casting from the older 4.0. It wasn't until I started doing more research on the engine that I realized this, but I did get the engine for a really good price that was too good to pass up. Being that I've already put in some time into this engine, I HAVE to make it work. The first issue that I ran into was with the driver's side motor mount pads on the block. on the older 4.2 and 4.0 engine, the top bolt pad is pushed back about half an inch, and on the XJ 4.0 they are flush with each other. So, I went ahead and cut the top one off about 1/2" and that left enough thread for the bolt. There is some space between the mounting plate and the block, but not much, that I am going to use washers. I'm hoping that will work. For the passenger side, I had to do some cutting on the CJ7 motor mount brackets and a bit on the block due to block webbing interference. Now, the next issue that I am facing is with serpentine accessory drive. I wish that I could just use the 4.0 accessories, but being that I did not get the harness and computer with the replacement 4.0, I am going with the carb setup. So I will be using the 4.2 intake. Unfortunately, the water pumps are different. The older 4.0 engines have the built-in power steering bracket on the pump, so it's not like I could go this route to solve my power steering issues. This is starting to be somewhat of a headache because it is turning out to be a much more involved swap than I thought. I wish that I could just go the fuel injection route and be done with these issues. This would allow me to use all 4.0 accessories without an issue.
I have an 04 Dakota 4.7 V8 4x4 with the 545RFE tranny. My plan is to swap in the 2.8 Cummins crate engine or possibly the 05 to 06 VM Motori 2.8 diesel out of the Liberty. Will the VM bolt up to my transmission? Does anyone make a bellhousing adaptor for the Cummins swap? thanks
Hey I was looking to upgrade my 1998 Jeep Cherokee SE’s ignition system. My intent is to drop the distributor and replace it with a camshaft synchronizer (https://www.morris4x4center.com/dorman-camshaft-synchronizer-oil-pump-drive-includes-sensor-dor-689200.html?gclid=Cj0KCQjwn7j2BRDrARIsAHJkxmw1PJPPvcy8YpgleZmsRNOW_q9zw78_4IXXuvfIbh7uufSEW3rMaaEaAtSzEALw_wcB) , and a RIPP 3.8 High Performance Coil Pack (https://rippmods.com/collections/jeep-wrangler/products/ripp-3-8-high-performance-coil-pack). “Viper Coil Kit” Will this work with my current wiring harness and PCM? or will I have to grab a 99-01 wiring harness and PCM to make this work?
