May be going to look at a d2 td5 landmark

As above thinking of going to look at a d2 td5 landmark, 127000 on clock been converted to coils from air

what should i be looking out for, i know rear chassis goes on them so thats 1st port of call but after than no idea with d2.

Check the red ECU plug for oil. If it is oily then it needs a new injector loom.
Check level of engine oil and sniff it. If it smells of diesel then it is probably the injector seals.
Usual checks for oil in water or water in oil.
Check carpet and headlining for damp.
Usual checks for bangs, clonks or any other noises when pulling away, stopping. Go up and down kerbs one wheel at a time.
Check all the positions on the transfer box.

cool cheers for that, is injector loom an expensive job?

Injector loom can be £30 to £75 depending on the quality and where you buy it from.
It's a job you can do yourself if you're so inclined, everything you need to know can be found here:

not fussed about doing it myself im pretty handy just like to know cost of parts thats not too bad either

cheers for link though
