Hi guys i just changed my sparkplugs and took the pics as i was doing it.its a twin spark 1.8 so i hope this helps out a few peeps.and i hope i did the job right lol
  CLICK ON PIC TO ENLARGE
Using an alin key turn and remove all four bolts which are circled in yellow below and also remove the oil filler cap.
  
Once the bolts are removed using both hands lift the cover of the engine reveiling the cables underneath as in the pictures below now replace the oil filler cap before proceeding to carry out anything else to prevent spillage.using the alin key remove the bolts which are circled in yellow.i have also included a picture of when the bolts are removed.
 
Placing a small flat head screwdriver under the clip just push up and pull the cable away from the plug.
  CLICK ON PIC TO ENLARGE
Placing a hand on each side of the spark plug cover plate pull upwards to remove the cover it will probably be stiff as it will still be connected to the plugs.
  YELLOW=BIG RED=SMALL
All you have to do now is just remove the plugs and replace them like for like.so not to get confused as i removed one plug i immediately replaced it and also cleaned the hole from which the plug was removed as there was a lot of debris and oil.
I have colour coded the picture in which size the plugs were.once plugs are replaced just reverse the process to get the covers back together.
 
Remember to place all the wires back into there clips before putting any covers on and on the ts version the is a wire which goes onto the top right handside bolt which is on the sparkplug plate.remember to replace the oil filler cap before going for a drive or the oil will spill over the engine.

That looks like the later Euro3 setup with both spark plugs for each cylinder running off of the same coil. On earlier Euro2 versions (pre mid 2000) each coil runs one plug in its own cylinder and another plug in a different cylinder.

Great guide  BUT there are one or two steps you missed/skipped [ see the bolded bits ]
Quote:
Once the 4 TORX [ m25? ]bolts are fully loosened, you have to remove the oil filler cap then using both hands lift the cover of the engine reveiling the cables underneath as in the pictures below..... now re-fit the oil filler cap.
Now using the allen key remove the bolts which are circled in yellow. I have also included a picture of when the bolts are removed. |

Just wanted to say thank you miximup for the illustrated guide It was really useful today as I'd gotten some oily water in the two left plug holes.
Thought I'd contibute a bit with this pic of my Euro2 version (1998 2,0 TS). As you can see there's only three screws holding the cover plate, plus as the wiring is a little different it needs to be loosened from its clips.

Hey Mix,
looks like the rubber rings around the plug leads that stop s**te getting down the holes need replacing.
Wonder if they sell them separately?
