For reliability which diesel Paj motor is best 2.8L or 3.2L

Any known problems for either

And which one is easy to work on ie. do you need to pull half the car apart to do a timing belt

Anyone put LPG fumigation onto one

Looking at an 04 NP and in the list of things on carpoint it lists Lpg Compatible; just wondering if these were designed specially to take fumigation

Also will an NS difflock fit an NP
