    Wow , what an ordeal !
    Since I was changing spark plugs , I figured why not put on a Mace Spacer ( 12mm ) .
    Changing plugs is fun like a barrel full of monkeys ( Yeah , not fun at all )

    To the spacer :

    [​IMG]

    My VZ has these little locator pins , and they didn't want to come out ...
    And the Mace spacer has no holes for the locator pins :

    [​IMG]

    So I had to drill some , Im just glad the gaskets were intact when the manifold came off so I could use them as a hole guide .
    I made the guide holes a little oversize so I had some wiggle room .

    Unfortunately the holes marked 1 and 2 did not really align well .. About 2-3mm to far forward .
    So the 4 big bolts in the middle of the manifold went in fine , but the single bolt at each end ( small bolts ) , they didnt want to go in ..
    Back to square one :
    I enlarged holes 1 and 2 a fair bit and elongated them back toward the spacer ( 4 big bolts ) , this time I did a lot of test fitting .
    Once I was happy with the test fitting , I assembled for the 2nd time ..

    This time things went well , and it went together reasonably easy .
    Just waiting for the blue stuff to cure ( 24hours )

    What a day !
    I sure hope the car still runs ..:rofl2:


    My advice to anyone :

    If you are doing it to a VZ , change your spark plugs at the same time ( Why not )
    Test fit the spacer , put the bolts in , dont use the blue stuff yet .
    Only if it test fits ok , then move onto doing a permanent fit !

    Appreciate your write up.
    Was it a 12mm or 25mm spacer?
    Please post your post install experiences.

    12mm

    I was thinking about the 25mm , but decided on the 12mm ...
    I was thinking I might be able to put the engine covers back on with the 12mm spacer ..

    The passenger side cover went on very nicely , but on the driver side , the front right mount for the cover will not hold properly ..
    The rear most mount is fine , I will take a better look Saturday and see if I can get the right front mount sorted out ...
    ( Driver side engine cover )

    Post ( Yes Im very interested myself )

    the engine covers don't fit at all with the 25mm insulators , I've got them on my SV6 , but I'm (still) working on a solution to have them fit , they're a good modification though I'm sure you'll be happy .I'm sure mine came with the holes for the pins though .

    Hmmm

    Some of the mounts for the engine cover are on the manifold , so need to do nothing there ..
    The other mounting points would need to be raised , or the mounting points in the cover lowered ..
    I tried to lower the front right rubber , but it was not enough .. ( only a few mm - would need 12mm )
    Would only need to be firm enough to stop the cover flapping about whilst driving ..
    Writing this an idea has sprung to mind ..

    I took my covers off ages ago.
    As far as I am concerned they trap heat and dust, and serve no other purpose than to make the engine look noice.

    BTW you had better change your signature as it ain't 100% stock anymore!

    Hmmmm

    I dont think the insulator/spacer is a big mod ( hotting up a car - in fact its supposed to cool it )
    I went for a short drive , and ??
    Yeah I dont really feel anything different , engine is a lot smoother but I think the new laser platinum plugs are responsible for that .
    I look forward to filling the tank , and then seeing what happens to the mileage ...
    Was about 15/100 doing lots of short trips , no freeways or long stretches at all ..
    Just driving through the local suburbs - local roads/streets so mostly stop start stuff and nothing over 2k without a light ...
    I will be happy to see a improvement ( how much would be the fresh plugs ? )
    So unfortunately no scientific - verifiable - proper testing results ...
    Manifold temp :
    With the car stationary for about 20 minutes , there is a slightly cooler manifold ..
    Before it would be warm enough not to be able to hold your hand on it for more than 5 seconds without serious discomfort , now you can keep your hand on it , its still very warm but not quite as warm as before ..
    Well , for me , it will be make or break on fuel consumption ..

    They do drop temps , I've found that with the 25mm insulator , the intake dropped a fair bit , for example going for a decent run town and country , stop , and start and so on , the temps dropped doing a before and after test , have a search and you'll find my results , obviously the top of the manifold can be a guide , as for fuel consumption , well my right foot tends to be a bit heavy , so I've not noticed much there .

    Im rather easy on the throttle !
    Latest fuel figures ( just filled the tank )

    Regular 91 octane
    27.5 liters for 209.7km
    13.2/100 ( No freeway ) mostly 60 - 80 ....
    So will see what happens !

    Ok , a fuel fill up has occurred , and it does not look good at all

    172.4km and 26 liters to refill the tank
    That would appear to be 15/100
    That is quite a difference from 13.2/100 before installing the spacer ..
    So I will , do another re-fill and see whats going on .. But if fuel consumption has gone up , ( and I really dont feel any increase in power what so ever ) I may need to remove the spacer and go back to stock !

    12.2L / 100km much too high for freeway use. ( A little bit of freeway, mostly Suburban streets )

    Another refill ... ( 14 October 2015 )

    261.2km Travelled ( No freeway at all, Suburban streets , 60 - 80 )
    34.24 Ltrs Used ( ULP 91 )
    13.1 / 100

    Previous refill 3 - 9 -2015 ( this one 14 - 10 - 2015 ) , so over a month between refills .. ( Yeah I don't drive that much ) ..
    Is there any evaporation ?
    Anyhow , so this last one was 13.1 / 100 and before the spacer 13.2 / 100 , so (?)
    I will keep posting as I refill the tank .

    Thanks for the data and write up. I have only recently got back into a Holden, 05 VZ wagon, so I am reading as much as I can on improvements, mods, problems etc.

    Now you must be able to say if the spacer was worthwhile? Perhaps some other complementary mods would help such as exhaust or intake would help the over all performance.

    Regards
