    Stupid me snapped a bolt on the Plenum Chamber :(
    So I am checking to find out if if I can replace the broken bolt or would I need a new Plenum Chamber?

    Which bolt mate? Inside or the lid? Iv got all my spares from when i put my spacer and insulator in. To be honest, they look like a standard bolt.

    More importantly, where is the rest of the bolt? Still in the inlet manifold? Can you remove it?
    No you don't need a new plenum. Whilst the plenum bolts are relieved in the centre and supposed to remain as part of the plenum, they can be removed by un-threading them out of their hole or vise versa for fitting a replacement.

    Good to know.. thanks for that info.

    Yeah the rest of the bolt is still in the inlet manifold :( Not sure how much thread is in it though... My torque wrench failed so i will have a look again when i get a new one hopefully this Sunday... I am sure it will not be hard to remove?

    So I can only get this bolt from a Holden dealer?

    Do you have a easy out kit? Used for getting snapped bolts out. Or even a reverse thread bolt/screw?

    Just dug through my bucket of VS bolts. Im going to guess its a seat bolt, its an allen key head, roughly the same length. Pack it up with some washers. That will do untill you get another bolt. See attached. Well you cant since i just killed my phone again :(

    I would have to get one.

    Looking down the hole on the plenum you could see where it has snapped off... Hopefully there will be enough there for me to use vise grips or something when I take the plenum off....

    Just about, roughly 5mm, from the casting marks in the manifold is where the plenum meets manifold.

    Yeah I knew about that, but I did it higher to compensate for the snapped bolt lol

    Does it help with performance?

    Mine needs a clean, but it is not that bad considering the amount of K's it has done...
