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 we -
The timing cover on a 4.2L is different than the 4.0L. TDC mark is many degrees away from the 4.0L damper mark, which is typically the damper used in a Mopar EFI conversion. Use true TDC for #1 piston when referencing TDC. If your damper mark does not match up with #1 piston TDC, place the #1 piston at true TDC and scribe a timing mark on the damper to match the timing cover TDC. This is one builder’s 4.0L/4.6L experience. He has a 4.0L in a ’98 TJ Wrangler and installed an OE 4.2L/258 crankshaft. The 4.2L crankshaft keyway did not match his OE 4.0L crankshaft keyway position: -
First, I'm not sure what I would do without your books. I'm a newbie mechanic restoring my own 82 CJ7. I have your Jeep Rebuilder's Manual and I have searched many forums. The complete MPFI kit came with my 82 CJ. I'm lucky because the kit was worth more than I paid for the entire Jeep. With some help from a mechanic friend the install of the MPFI has been pretty straightforward. I still have some factory wiring issues (what I need to use, what I don't) but I'll go slow and steady and figure out. My question is mainly around what needs to be connected to the charcoal canister that c

I recently got a 1989 Jeep YJ that sometime in the past, had the Mopar 1994 FI conversion installed on the engine. While the Jeep came with a lot of documentation about the other work done on it, there was only one page concerning the FI conversion. The problem that I am running into is this: If the alternator is hooked up correctly, the engine won't turn off by using the key. If the alternator is not hooked up correctly (meaning that it's not charging) the key shuts off the engine. I thought that it might of been a bad ignition switch, but after changing out the ignition switch, the prob -
Happy Thanksgiving to all! I've posted before that my CJ-7 has a Cherokee 4.0L in it, but it's not really that simple Here is the history as I know it or can guess from some evidence: 1. Originally a 258/4.2L straight six with the FrankenCarb--this one was sold in California, so I'm sure it was extra-special. 2. MOPAR EFI kit added to the 4.2L. It seems this addition happened sometime after 2000, as the MOPAR labels for the kit have a 2000 copyright on them. I learned from the shop that did most of the work on this Jeep that the lady I bought it from purchased it sometime around 2001. It w
