Your bad manifold gasket... are you sure you don't already have broken bolts? That's usually the cause for the leak. Reach in, get a light, feel and look, and count all the bolt heads. I bet you are missing at least one. When you take out the bolts, to avoid breaking them, use an impact. You will have to go through the wheelwell, and use some extensions and wobblers. It will be a pain, but an impact will spin them out instantly without breaking.
