First off, no replies about a WJ will not work in a XJ. It gin will work, just takes a little work, which is why I am doing this thread.
The 4.0l in my 94 Cherokee throw a rod and made a nice window in the block. The engine was close to 600,000 miles with 200,000+ since last rebuild. Yes, It is the original engine. I knew I should have changed all the connecting rods during the last rebuild.
To answer why I would use a WJ engine, It was five miles away @ $250. Next closest engine was about 4 hours away @ $500+. The engine build date November 7, 2001. I would rather replace the mechanical fan with an electric one and use the accessories from the 2001 engine since there is a tensioner, but the A/C in my Cherokee works and do not want to rerun all the A/C lines.
The areas in yellow need to be drilled and tapped, the areas in red need to be material relief.
To get the engine mount brackets to fit properly, only the rear most boss on the driver's side needs to be cut back and drilled and tapped and a spacer installed on the front boss on the passenger side. These are the only problems I have found to get the engine to work in a XJ.
