Re: 145 junior 1600 twinspark - spark plugs
Dead easy, took me about 30 mins as the light was fading, remove 4 spline screws and take off the oil filler cap, lift off the plastic cover.
Disconnect the feeds to the coil packs (x4) and using same spline bits remove the bolts holding down the coil packs. GENTLY ease the coild packs up from over the plugs, pull the 4 coil packs up evenly and pull the 4 'ordinary' plug leads up to start with. Once you have removed the coil packs etc. you will have access to the 8 plugs, drown them with WD40 and spray a little down each plug cap to aid refitting. Then unscrew and remove.
Fitting is the opposite of reversal (Duh) and make sure the coil packs & secondary leads are clicked home.
All in all a fairly easy job and access is not as much of a problem as some cars I've owned.
