Hi,

Depends on what part of the engine was slugged up. If its the engine blocks then seems you had a gasket leak and water got mixed with the engine oil but still repairable.

However, if the car overheated and pistons got jammed then going a good engine from a wreck is your best option. Re-Building it will cost you too much and not every mechanic can rebuild an engine properly.

If they are saying it has sludge, and time for a new engine, try running some cleaner through the oil of your current engine.
Or running a diesel grade oil with higher detergents to try and clean it up?
If its all ready basically a goner what do you have to loose??

But these are almost identical (possibly are identical mechanically, just the ECU programming may be different) to the mitsubishi 3.5. dont know engine code. The one from the Pajero.
So i would ask a mitsu engine specialist or japwreck style place

I had a look at the 3.5 Pajero engine a while ago, only difference I could see was the sump was a slightly different shape, and the oil filter was on the other ( Mitsubishi Magna) side. Neither probably a big issue as you could probably swap the parts over. Even the electrics seemed the same.

This add suggests that the engine internals are the same as well. http://www.store.partsdinosaur.com/page435.html

Other option is the Hyundai Terracan, engine, gearbox, and T/C are all identical to Sorento up to 2008.

Look for a product called CEM on line, it is designed to de gunge small Japanese diesels. Try that and then as suggested above run diesel engine oil for a few changes to clean the rest out. I run diesel oil (mixed fleed rated) in mine all the time, the engine is super clean inside, no lifter noise, and it burns no oil at all at 150,000 Km.

i believe the gearbox would be different after the 2004 sorento. That is when the 5 speed came out rather than the 4 speed.

If you want to get down to the nitty-gritty you have to consider the chronology. The Sorento gearboxes (auto and manual) were designed to be a common fit for both the 2.5lt diesel and the 3.5lt gas V6 (& later 3.3/3.8lt variants).

The Sorento chassis and original diesel engine (also possibly the 2.4 gas variant seen in some territories) were lifted from a hyundai/kia truck line.

The odds are that there may well be some mismatch between direct Mitsubishi parts and Kia parts in the engine/bellhousing/transmission attachments. My thought is Kia may well have redesigned external parts of the V6 to match the existing chassis/transmission configuration. They had to do the same exercise anyway to turn the V6 90 deg and fit it in the Sedona. (which didn't have the Sorento's 2.5lt Diesel - it came with a 2.9lt variant).

You are correct, I forgot all about the 5 speed. :) The 3.5 engine and T/Case is still the same.
