New guy here and also new to new to trucks or anything with a V8. I raced old Rx7s for awhile, and also work as a C130 engine mechanic, so I'm handy with tools. Anyways, k1500 with a 305. Coolant on top of engine right on either side of the valve covers. I don't see any lines leaking, or any residue coming from the themostat gasket. So I'm shooting for a intake manifold gasket. Anyone else agree or had a similar issue? Im thinking it could be coming up from the bolts, and just sitting right in those pockets on top of the manifold.
