Well, I have not had a chance until now to really look and figure out the leak. It turns out that it is the bolts that connect the manifold to the cross-over pipe on the drivers side. The bolts rusted away in the center. So, there is a portion of bolt nut still on both sides.

Is it more of a "Stud" in the manifold? If so, do you think I can fix without removing the manifold. What would be the best way to get it out? Do I have to drill it out? I've been soaking it in penatrating oil overnite and will add it continuously through the weekend where I'll try and tackle it.

The gap is not too severe, like I mentioned earlier...as it warms up and the pipes swell...the noise is gone.

What would you guys do? I'm not opposed to a cheap fix.
