Putting the year of your car will help they produced them from 1969 - 2002 odd with a variety of Rover engines before we can help really.
It's chain timing and a Land Rover Haynes manual covering the year is your friend for the gearbox and engine.
The rest is pretty agricultural really, which is a big plus when doing your own servicing and repairs as quite a number of us older guys prefer to do.
The owners manuals do appear on fleabay etc but are pretty useless really.
