I need help changing spark plugs

[RobboR]

ive just took off my engine cover to get at my plugs but i believe the coil pack needs removing first? How does this come off? i thought there would be a guide and ive searched all over but no joy. I didnt want to just pull at it so thought best to ask first.

i step by step would be spot on.

im basically ready togo.

also do the plugs need to have a certain gap? or do you just tighten up as normal.

cheers

they are basically a plug
they just pull up

 

[Damoegan]

The coil packs are either bolted/screwed in or just pushed in. Just remove the bolts/screws (if its that type) and prise them up with a screw driver. Simple

 

[RobboR]

hmm im sure it didnt look as easy as that. its an LCR if thats any different.

The coilpacks can be tight and need a good firm pull upwards with your hand,disconect plug with wires to coilpack first using a small screw driver to press retaining clip in on the plug,being carefull not to snap it in the process.Then just pull coilpack up,they can be tight.Remove plugs with plug socket and long reach extension and refit new ones making sure it is seated right with thread,start it off with hand first and then tighten down with rachet,the washer will get compressed as it is tightened up and once this happens the plug should become tight.not sure on torque setting for plugs,but dont over tighten them.Refit coilpack by just pushing it back over plug and conecting coilpack plug.If you have got new plugs and they are for LCR then they should be at correct gap already.Hope this helps.

...making sure it is seated right with thread,start it off with hand first and then tighten down with rachet...

Great re-fit advice.

Be VERY careful not to mis-thread - remember that it's an ally head, which is exactly why AA & RAC etc inspections won't run risk of doing a compression test.

Cheers for that guys, il give this ago later today and post how it goes.
i got the platinum NGK plugs for the LCR

Which of the things on this page would be recommended for changing the plugs?

just get a spark plug socket, they come in most socket sets, they are long, thin with rubber inside to grip the plug, then use a ratchet extension onto it, then ratchet them out. back in ust the socket and extension by hand until they grip then torque upto 30nm


coils, undo the wiring clip and pull up. they will pop when they come out, push back down to refit.

gap to 0.028 if mapped, 0.032 if not.

to be fair its not quite as easy as made out above as two of the coil packs are not accessible without undoing a few bits. (the right hand two looking at engine).

However this isnt as bad as it looks, there is a bracket with an allen key bolt securing it and perhaps another bolt to undo, everything can be moved out of the way as they have rubber hoses which are compliant. So not need to undo any hoses or anything.

where did you get these two plug gaps from did not know you need to change plug gap on a remapped car my car has a revo remap never heard of this.?

Id like to know more about this as im in the same boat as you?

It is stated on many forums as the above. Also a smaller plug gap puts less strain on the coilpacks, so they should last longer

Another trick to help with starting the plug into the thread in the head is to use a length of tightish fitting rubber hose on the end of the plug. You basically turn that to start threading the plug in - if it starts to cross thread the hose slips around the top of the plug instead of chewing the head

 

[james walker]

why the need to use hose when the extensions on the spark plug socket. just hand tighten to get the threads started. dont be scared of it, just careful to get the threads seated then its fine.

Bit of a hangover from my old Rover days, although once you strip a sparkplug hole, its the one and only time you ever do it.....

Jees what seemingly understatements of ease.

Had a quick look today at the right had side ones that are covered with the metal bracket. You undo the brackets but there's so many bloody pipes going over and across you can' just move them to get the coil packs out.

thats the n249 bits take them off
