Changing VE/VZ spark plugs?

[RiCeY]

Ignore the manifold replacement one, at least most of it, as you dont need to actually remove the manifold.

Just loosen it to allow it to be lifted enough to remove coilpacks and plugs.

I replaced the spark plugs in my VZ commodore yesterday and it was very easy. It took about 40minutes to do in total.

As has already been said you need to remove all the manifold bolts and lift it slightly to allow you to remove the coilpacks and plugs.

Does MY10 sidi require manifold removal to change the plugs ?

 

[RiCeY]

The ones with the plastic manifold dont.

 

[Ron Burgundy]

That sucks. How long the plugs on it should last anyway ( sidi)

Depends what's in there.

From memory coppers are 20k, platinums are 80k and not sure about iridiums. Somewhere In between?

My alloytec has it in the manual for the 120,000km service, so just check ur manual.

My aloytec also 120,000 just about ready, did wonder about the manifold .. If I remove all bolts apart from the 2 listed above and lifted it up is there still chance I could ruin the gasket by doing this?
(also what a stupid place to put them - doesn't make it easy)!

ricey, is it worth putting on some anti seize on the spark plugs?

Don't use anti sieze if the plugs are shiny metal as you can easily over tighten the plug snapping the end off.
Check. http://www.ngksparkplugs.com/pdf/TB-0630111antisieze.pdf
