I've had my intake manifold apart like 87 times and I now have a vacuum of -15psi at idle like I have a vac leak in the manifold somewhere. All hoses are fine so I assume it has to do with the gaskets leaking somewhere. I was going take it apart AGAIN and use the red liquid gasket stuff to seal it up. That should be fine right?? Anyone do this before?

ya, you can ask Urban Customs, when we put his turbo manifold we used gasket maker, the color that they recommended (dont know if it has to do with it) is cooper they said it would be the best one to use for stuff like that

yeah its fine, use copper silicone, high temp!

I would use Permatex Hylomar with the factory gasket... This is the stuff that Rolls Royce developed to seal flanges on their jet engines. Non hardening, so it shouldn't be nearly the bitch to remove..

Try the stuff in cans they sell at autoparts stores that you spray it where you think the leak is and the engine will idle bad or stall and just keep trying different spots to make sure. I don't remember the name of it just tell the guy at the store what you need it for.
