Engine broken: What should I do?

I agree, looks like this engine should work. Ideally you should buy that engine, and use it as a donor to your engine. The 4.0 stroker websites have a lot of information regarding the different year blocks,heads,etc. and which are the best. This is a good website: http://www.angelfire.com/my/fan/stroker.html

For example take the block from this donor engine, use the head from your old engine (inspect it first obviously) because the head from newer jeep engines is typically better. I recommend doing new crank/cam bearings, new camshaft, freshen up the engine while you have it out. New lifters on the head, definitely. New oil pump, new water pump - The old engine blew up for a reason. Check all your piston rods and balance them, since the piston was damaged. Maybe take the pistons and rods from the donor engine. Otherwise keep as much as you can from your jeep's engine since the sensors and electrical will match right back up easily.

If you can get the replacement parts to freshen up this engine where you are, then a fully rebuilt 4.0 will last you until the jeep falls apart. Also make sure you have a guy doing the rebuild who understands engines! The 4.0 is not a very complicated engine.

I agree — buy it. If nothing else, you can use the block and internals....and swap your head / accessories / brackets / etc. over if necessary. I also vote for new pistons / rings / cam / internals in the replacement block

It's important for me to understand why my engine was broken, especially since I only have 191,000 km on it.
I tried to see with my friend who is an expert in mechanic and who takes care of the repair of my vehicle. What he noticed when opening the engine is that one of the six rods present was blocked and did not turn around its axis ... The other rods were OK. And he found traces of charred oil all over the engine ... His conclusion was that the waste caused by the burned oil had clogged the oil circuit and therefore the connecting rod was out of oil. caused the problem.

Although I did not drive a lot with my car and regularly flushed, he thinks the old car owners were probably responsible for poor maintenance.

I do not know what you think about it but it's the only explanation I have so far.

That's a nasty engine...

I would bet they went 10K+ on conventional oil regularly.

I think so too ... in any case I hope that it is that and that I have no other problem like the oil pump or other ... Especially that I checked daily the level of oil engine and I had no problem ... Even the dipstick on the dashboard was mostly above average.
Maybe the only thing to report is that I had a few drops of oil flow under the vehicle (between the engine and the gearbox). I had already bought a new Parasail but I did not want to replace it for the moment ... I do not know if it could be the cause of my problem, especially with the contact of the sand with the underside of the car but I do not think it's the real reason.

I had a similar situation happen to me this past fall. My engine went out (2.5L), I haven't torn it apart yet to find the culprit, but decided to do an engine swap at that time. So if I were you, I'd take this chance to possibly throw something fun in there, like a diesel, V8, or whatever else is reasonably priced that you can get your hands on. Especially since finding a new 4.0 is going to be a challenge for you. It's not much extra effort to swap something like a V8 vs putting another stock option back in.

The idea tempts me, but I do not know at all what diesel engine can fit my vehicle ... Here there are many used engines Mercedes, BMW and Volkswagen diesel available , but I do not know how much It's hard to get one of these engines work properly on my car ... I do not understand much about mechanics, but I think a replacement like that requires a lot of modifications and new parts (maybe adapter or others) , so it can be very complicated for me. .. Then I have a 32rh automatic, and I doubt that this box will be compatible with a Mercedes engine or a Volkswagen TDI ...

That is an insane statement, sorry. It is WAY easier to put the original type engine back in vs changing to a V8 or anything else. A 4.0 will bolt up, just the same as it does now. Nothing else is a bolt in affair... Nothing.
