I am afraid this sounds like a lower intake manifold leak, but other possibilities are the thermostat housing or a faulty upper radiator hose. The upper radiator hose wraps around behind the A/C compressor before continuing back up front to the radiator.

i found a hex plug in the block that is rusted out looks like the leak came from the intake man and was leaking for a while not to bad but bad enough and it ran down to this plug and the rest is history thanks for the feedback
