ooops. sorry ill shut up 

i thought a coil pac and dispac were the same thi...... actually dont worry bout explaining, im too thick!!! 

coil packs just sit directly onto the plugs ..... no HT leads 

Did they produce one for the 2.2 which was not bolted down though?  :-/

Vauxhall say this is how its should be

No.

It did have the head changed, at a Garage about 3 years ago, Before I had it mind !! 

Is a 2.0 head going to make much difference to the car? other than bolt threads for coil pack??

Does make sense if 2.0 has dispac. the coil pack at the moment has two wires running off the two bolts to the battery,

I knew it wasn't right,

Cheers also Zulu for the link on changing spark plugs, Clearly see the thread holes are there!

Errrrrr 

You what? The coil pack is directly wired to the battery!?

thats a really good guide and i see what it means in my own basic way 

so as the coil pack is long and sits on top of the plugs how come the v6 has a dispac instead of also just sitting on the plugs?

sorry if thats a daft question but im slowly learning basics 

ps sammo not wanting to hijack your thread, ill bugger off after this 

[Sammo]

Yes directly to the negative terminal, Trouble is i'm no expert with car engines but know a little,

this was done according to an invoice to earth the coil pack,

Its a real mess,

2.6/3.2 has a coil back, but the 2.0 had a dis pack 

Coil packs where introduced as part of the DBW improvements with the new engine, coil packs remove the need for plug leads

What about the original plug to the coil pack? I assume that's plugged in.  :-? :-?

If you have the invoice go ask the garage why the hell the used a 2.0 head instead of the original. Even if the 2.2 head over-heated it could have been skimmed.

Can only think it cracked  :-/

Don't apologise, I am also on the learning curve, and sometimes it gets very steep 

The late V6s have the coil / dispacks (not sure of the difference) in the same position as the one described i.e. directly on top of the plugs, hence no HT leads - much easier to get to.

nice one 

so in essence the actual function is completely the same but the insertion of a coil pack and removal of leads creates more engine space and easier removal/fitting?

ive been reading the 'general help' section (never usually commenting) to get some basics. ill know im a mechanic god when ive learnt to change spark plugs by myself

Some will argue it was a backwards step, coil packs are no more reliable than dis pack it seams. But it does look neater, less clutter.
