No more difficult than any other car.
Check this thread for more info. TB45 is the same as TB42.

paul1351,
Make sure you make the adjustments with the motor hot or at least warm. If you do it cold, you will probably end up with a noisy tappet or two i.e. too much clearance - and/or worse, a tappet or two with too little clearance (worse because you can't hear them), which might be a cause of a burnt valve. Take your time and when you think you have finished, turn the engine again and re-check all clearances - you might be surprised.
