Hello, I have a 2003 Dodge Ram 1500, 4.8L, V8, 4x4, SLT, extended cab, Gas, with 120k miles. I started to replace the ignition coils and spark plugs, and 4 of the 8 bolts were so rusted they broke off when I tried to remove the nuts. These are the bolts that up through the intake manifold, and have a double nut. They serve to hold the intake manifold down and then allow the ignition coils to be bolted down with a nut. How can I replace the broken bolts? Can I just remove them from under neath the intake manifold, and replace with new ones? Are the bolts threaded into the block/intake manifold? I am hoping I do not have to remove the intake manifold to do this. Any help would be appreciated. Thanks!
