It's not difficult, but it is time consuming due to all the covers etc. that must be removed. You may wish to replace the HT leads whilst you're at it (taking care not to trap the coil R/H pack-distributor lead on reassembly). Use only Denso or NGK iridium plugs. Allow a full day, because this is not something that can be rushed. The lexls.com tutorial tells you all you need to know. Good luck.

well the plugs and HT leads are now done . time taken was 2 and half hours . not as hard as i thought it would be . done it on holiday . took tools with me hoping i had all the bits i needed , stripped off all the parts and done it on the camp site .

thanks all for advise ..

keiron.. :D
