If so, there is your problem, your trying to use 2 sets of gaskets and it leaking through the two. The intakes with the o-ring gaskets made in it , you don't use any other gaskets.
Just use a little RTV around the coolant ports only, and you'll be set....
Dusstbuster said:pinhole coolant leak or pinhole air leak? so it probably wouldn't hurt if we did a small ring of RTV on the heads around the coolant ports or would that in turn make it sit a little higher possibly and then cause vacuum leaks...

Dusstbuster said:Ehh...what? I know for sure there isn't a gasket on the manifold. That picture is just of the manifold upside down with the 2 gaskets I just bought today sitting on it...

When I did my intake originally w/ the NPIs, put the gasket onto the manifold first, then sealed where the gasket missed. If you put it onto the head, there is no way of telling if you've used enough rtv to insure a good seal... either that or you use way too much. It is really hard to tell from those pictures, but it almost looks like you're trying to seal up the gaskets on the head, not where they miss on the intake. here is a picture of my intake when it was done..
As you can see, the gaskets don't seal the port on the side facing the runners, so you just need rtv there, not all over the head. I almost guarantee you have a massive vacuum leak where your gaskets are not sealing the intake ports properly. Thats an easy enough fix, but I recommend using the PI gaskets this time though, and only using a dab of RTV where it doesn't seal the water jacket all the way.

Where did you purchase the intake in this picture, and is that aluminum on the front of the intake?

Someone wanna inform me exactly what knock/ping/detonation is supposed to sound like? When you're under the car it sounds like every once and awhile someone is like inside the exhaust tubing and slightly knocking on it...a metal creaking noise/knocking noise. I'm assuming that's why it's called "knock"?
