GU Patrol 3 litre longivity

[Chaz]

Hey Chaz thanks for the info and balls ! being a manual i am guessing the box or motor will have to come out owing to pressure plate. Any idea which manual on here suits my 2001 diesel zd30 di .. i dont seem to get the links come up for me

Sorry, I can't help you with the manual - I haven't downloaded them.
It's always easier to pull the engine out to do a rebuild, but if you're just going to replace the pistons, it may be easier to pull the trans out. Either way, one of them will have to come out to remove the sump.
