97-02 guaranteed. If I'm not mistaken the engine has been on the chrysler computer since 1991 but I'm not certain if the plugs are all the same for anything earlier than '97. Anything later than '02, maybe someone who knows for sure can chime in? I don't believe any changes were made right up to the end of the TJ era, but I can't find documentation to support that. Google has failed me.

4.0

I believe that 97-99 are the same but in 00 they got rid of the distributor. The engine wire harness is a little different as well.

and starting in 02 they improved the head IIRC. Are you sure the engine is blown? If there isn't anything obviously broken it could be a good time to do a stroker.

Did you actually bend something in the engine? Have you done all the usual stuff to an engine that sucked in some water such as removing all the plugs and cranking the engine to pump the water out?

As i said in my email to you the 97 to early 99's are the same, the late 99's and up have no distributor, and run coil packs. They also changed the cam so that they use a different cam sprocket and cam retention plate.

If you're looking to put a 4.0 back in it you need to get a 2000 and up engine.

Just buy my 318 swap

The OP is a friend of mine and lives in my home town. He told me last night he shot a rod through the bottom of his oil pan, says it is about the size a .22 caliber round would make.

is that totally true though? if he's just replacing the "block" then all the rest of his stuff from the 00 will bolt up to the new engine.

There are bosses on the 00 and up engines to bolt the coil packs to. The older 97-99 blocks dont have them. I'm sure there's other things about the two different year groups, but this is just a few things i've learned while looking up stroker builds.

I bought my rubi in 03 with TWO rods pushed through the oil pan. The other 4 have beautiful arcs in them I purchased it from an insurance salvage sale; had 12,000 miles on it and still had that new car smell. My title reads : Previously had flood damage

To make it easy on your life, get any 4.0 2000-2006. These have the Coil rail and camshaft position sensor. Any 4.0 from any model; TJ, WJ, XJ - auto or manual will work. I stuck a 2000 WJ 4.0 w/ 18,000miles in my rubi while rebuilding the stock 4.0. I found it for $800 bucks and was shipped up from Houston to the local scrap yard. You would probably need to swap over a few sesnors as the plugs can differ b/w models. IIRC I had to swap over my TPS and oil sending unit.

Please do not make the same mistake I made by getting a replacement or simply rebuilding..... STROKE IT. Has I known a Jeep (amc) 4.0 was built just like a small block chevy before hand, it would have been no problem.

An encouragment picture:

FWIW: I would rather replace the engine over dropping the tranny ANY day

to buy it back i would need a liscence from the state of ill to rebuild salvage title vehicles and go to auction to get it... Unless that said vehicle is nine yrs or older. Hey Ill jeepers its time for a fire sale all must go but you gotta have parts to replace after market parts with. Check my sig and pm me ill make sum helluva deals. Probably getting an 04 rubi next week so at least i got something to look forward to
