Sorry, I can't help, but I was wondering how a failed injector could destroy a piston, bore and valve. A friend of mine had to have new injectors and pump on his Peugeot 307 under warranty, but it just produced a lot of smoke and rattling noises. The engine was fine.

Navara also has a reputation of engines "letting go" and at far less milages than your X Trail !

the 2.2 engine is a nissan engine, the only problems i had was a leaking intercooler, and a weeping sump plug after a main dealer service, my son has it now with 35k miles.

At present i have the 171bhp 2litre which is a renault engine, the car has been 100% trouble free, revs like a petrol engine and still returns 40 plus mpg, but i still prefer the first xtrail, on the other hand the wife much prefers the new version. however only done 7.5 k miles, engine is nearly run in, so i can now pull 6th gear at 1500rpm, something not possible when new.

It's an 'old shape' with the YD22 Nissan engine.

Currently in dialogue with Nissan Ireland.

Hopefully I won't need to gamble with a Small Claims Court case (which, since January 2009, can be done against companies based in other EU countries via a UK county court), which might be difficult to enforce the judgement of anyway.

Saw the engine block on Friday - burned out valves, piston head wrecked, bore damaged by piston.

Clearly caused by a massive overfuelling resulting from the injector failure. The heat generated by compressive explosion must have been massive, looking at the damage.
