intake manifold leak
Well I finally fired up my engine today, all of one second. After doing this a couple times, I noticed that I had gas leaking out of my intake manifold.
The reason why is I had to connect a S4 lower manifold with a S5 upper manifold.
The problem with doing that is all but one stud aligns. I asked around and everyone in the second gen forum, and other threads I searched just said to remove the stud and it will be fine.
Well now its leaking around that area, just like I thought it would. Does anybody have any ideas on how I could recreate the clamping presure in that area of the manifold since I cant use a nut or bolt? The area of the manifold in question is where the last nut securing the mid intake manifold at the rear of the engine.

I know I should have searched, lol but I had to run off to work. Those helicoils seem pretty cool.
Anyway, I'm confused on how exactly taping in a helicoil is going to help, I have the missmached bolt holes, so why shouldnt I just tap a normal hole, (assuming there is room for one, I'll fine out tomorrow) I guess the heli coils hold better, but that assumes that I have two holes ligned up to put a bolt through, which I dont.
I think I'm missing the idea being presented to me here....

I think the suggestion was made, while missing the point of the offset/misaligned hole pattern. Your best bet is to drill and tap a new hole providing there is enough meat left in the casting to do so. Good Luck!
