You can see the coolant pooling in the crevaces on top of the engine, specifically the intake manifold. It will also smell like radiator coolant due to it evaporating on the hot engine. Most of the cost is labor due to the many parts that must come off the engine to reach the intake manifold and change the gasket. Mechanic said that all GMC/Chevy trucks of this era will leak around 90,000 in this same manner.
