Ok she past her MOT and time to keep her good so going to change the timing belt on my 1997 Disco soon cos no idea when last done or ever! Iv had a look and seen that there have been problems with the timing belts and various upgrades available, its there a way to know if it has been done already just dont want to buy a kit and chnage the same thing. Other thing is to lock the engine do you have to buy a kit i know when i done my old pug diesel it was just 3 M8 bolts and a 6mm drill bit can you improvise with the disco too. Anything else to be aware of or help much appreciated. Gary
