VZ alloytec (how do i change spark plugs)
I am wanting to change plugs on my VZ alloytec,my question is how do i get to them and how do i replace them.is it a hard job?

its a manifold off job

As mentioned u have to take off the Manifold,
There are 5 bolts ontop, undo them, then disconnect all hoses it will take abit of effort to get off.
When u take it off put a rag covering each of the 6 intake holes to stop dirt entering. All you have to do now is disconnect each of the coil packs to access the plugs.

Are the manifold bolts need to be done up with a tension wrench.
And is the job able to be done by someone with a bit of mech knowledge or do you need to be a qualified mechanic.
How do you get the plugs out (do you unclip the electrical harness and undo the one bolt to free the terminal from the plug?)
when do u chage them on the sv6 my book says 2 different times one page says 90 one says 120 which one is it???
What are you referring to? tension?
Tension: 16-20Nm for the plugs.
Tension the bolts for manifold
Of what I can see, it should be 23Nm.
Shit I totally miss read your post and went off at a tangent. I had a look through my owners manual (which covers the stock and the 190 model) and I could only find 120km interval. Flip a coin I guess.
now choppin the VZ
I'm lifting the manifold but don't want to do damage. I've taken out 5 bolts and disconnected 3 hoses, one at the intake and 1 on each side halfway along. I've got the front loose but something seems to be holding it at the back. Lifting harder is probably the way to go but wanted to check. Its a 190 not that it should matter. any quick advice would be appreciated
ps how the hell do you get the plugs out after undoing them, they're a mile deep

That the automobile has practically reached the limit of its development is suggested by the fact that during the past year no improvements of a radical nature have been introduced.

there is a bolt at the very end of the manifold only a short one, look over the back near the map sensor and you should see it, its next to it, have you also disconnected the lead to the variable intake actuator?

I know this post is very old, but your doing it all wrong. To save time, and the paper gasket in between the 2 halves of the manifold, you leave in the passenger side front bolt, and the drivers side rear bolt(very back of motor). These 2 bolts don't go all the way through, they are only into the bottom half of te manifold. This means u can then just chock up the front of the manifold with a block and then proceed the plug change. You should never have to replace the gaskets when doing plugs on a vz. Ve's are a different story tho, as there is less room.

care to elaborate on this?
if your lifting the manifold chances are the paper gaskets will break therefore, you've gotta replace them

the voices told me to
sounds too much like hard work. think ill drop mine into the mechanics and go fishing.
i do as the voices tell me

If you wanna pay me, I'll come and do them :P Only a Stones throw away from Kanwal
If it's not a Symptom its not relevant, and if its not relevant I don't care!

The manifold is a 2 piece item, if you do not undo the front right and rear left bolts the manifold does not seperate therefore the paper gasket doesnt get damaged.

the inlet manifold is a once peice....
and if you dont undo all the bolts...how are you suppose to lift it? you'd still not get any movement

never said i did, but i've pulled the inlet manifold off my old vz and that was my experience so, i'd appreciate the idiot comment being removed...
cheers

The inlet manifold is a 2 piece, seperated by a paper gasket.
Not removing the bolts I mentioned allows the whole manifold to be removed without seperation. Those 2 bolts only hold the two parts together, not hold the manifold to the block.

No. You made a dumb comment based on doing something wrong. Idiot suits.

how is following a set of instructions, doing something wrong...?

Because the instructions were wrong. Holden tech just said so.
