(Mace's) 25mm Insulator and Plenum Spacer questions - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

nikos30 · 06-07-2012, 03:08 PM

I figured that I'd make my own thread, with my own questions because I keep asking questions on other's threads.

So I have the Ported intake manifold, the plenum spacer, and the 25mm insulator and I have already installed the PIM and the insulator. I am now installing the plenum spacer.
My plenum spacer did not come with the 4 bolts that hold down the manifold. I have the new ones that came with the insulator when I bought that. I am worried that those bolts will not fit. I am not installing anything until I am sure, because I am leaving tomorrow afternoon...

Also, the bolts that came with the insulator (only 4 of them, the ones that hold down the manifold) aren't all the same length. Only one of them is shorter than the others. When I installed the insulator, I just ignored that it was shorter and I used it as one of the four. It worked, but if its wrong, or if mace was supposed to send me another bolt, ill go buy it. idc, whatever makes everything work properly without cutting corners in the end.

Thanks for the incoming help (please be some)

Got any pictures? I can help you with the IM bolts but don't really understand you. How many bolts did u receive with the insulator?

I got 4 with the insulator. 1 was shorter than the others. I installed everything with that and everything worked fine, and everything was tight.

I cant take pics because my phone wont save them. I dont have a camera...

To the best of my knowledge, you need 4 160mm (6.3 inches) bolts to retain your Mace 25mm insulator and 12mm plenum spacer. I'm talking about the 4 bolts that pass thru the plenum cover and IM.

I haven't installed my plenum spacer yet, but thats what I'm expecting to use.

They are 8mm X 1.25 X 160mm bolts.

I believe I have 1 extra- if you need it.

For the 4 bolts in the center, do I use that oem gasket for them? and where do the 4 spacers go, underneath that?

SO I put (from bottom to top) the gasket, the 4 spacers, then the cover. is that correct?

Best results would come from (top to bottom):

IM cover
OEM gasket
Plenum spacer/metal spacers
gasket maker
IM

The bolts pass thru the metal spacers- they are there to keep the metal cover from bending (and leaking) when you tighten the bolts.

Use gasket maker on both sides of any flat surfaces that don't have a gasket including the metal spacers (bushes).

PM your address and I'll ground ship you a bolt- you can buy me a beer sometime if I'm ever in NJ, and introduce me to Snookie of course!
