I am drilling the boss so I can mount the XJ water pump.

Here's my reasons for using a WJ block: The first time I rebuilt a 4l engine in my first XJ (88), the "good" used engine someone sold me was so beat down, it might as well been a dead horse. To say the valve cover was clogged with sludge was an an understatement. The sludge had solidified into...

The rear main seal for 2000+ 4l do not have the locating ears of the earlier seals. the earlier seals can be used in the later main cap with the carful trimming with a razor blade. Ask how I know it can be done. :laugh::laugh::laugh: 87-99 seal...

Except for not taking the timing cover off the XJ block, the price of WJ block was dirt cheap plus machine shop work and gaskets/ seals. My total is about $1500 USD. I would have preferred having a ZJ/XJ block, but living in rural America with only two salvage yards within 30 minute drive...

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...

Besides the untapped/changed bosses, I noticed the oil filter boss was raised higher on the block. Bye troublesome oil filter adapter.

Lets dig up an old thread and add more information. Thank Google for finding this. Here's the deal. My 94 XJ just suffered some grotesque metal fatigue in the #1 connecting rod and added a nice window to the block. What can one expect from the original engine with 500000+ miles. Should have...
