leaking exhaust manifold

I thought it sounded like I had an exhaust leak, so I crawled underneath with a light while it was running. On the driver's side, I can see around three of the four ports where it looks like it's leaking and there's some wet residue goo. One of them was even bubbling a bit. I put a ratchet on the bolts just to see if any of them were obviously loose, but didn't seem to be. I didn't wrench on them too hard, but none turned at all.

Suggestions? Tighten bolts? I don't want to over-tighten and break any. New exhaust gaskets and bolts?

By no means am I a manifold expert, but I'd be very, very cautious about overtorquing the bolts. I'd be much more inclined to replace the gaskets than go cranking on bolts, break something off, and then be stuck trying to fix the aftermath. Gaskets seem like the more plausible culprit here.

Interesting...It doesn't really look like there are gaskets on mine now.

My 2002 does not have exhaust manifold gaskets. You do not want to break an exhaust manifold bolts. Trust me on that.
