Please soe tell me what is going on....I think it is a blown head gasket.....Is the Rad. Fluid killing my bottom end????? What is the clankig I was hearing???? Connecting rod or bent Valve?!!!!!! or crank bearing?

 

your radiator has a hole in it that connects your tranny cooler lines to the water area if you had a blown head gasket you would have antifreeze in the oil making it milky colored, drain your oil, drain the radiator and flush it, then disconnect the tranny fluid lines and rerun the motor but no moving or you will fry your tranny from not circulating cool fluid through for about 2-4 minutes then flush it out and see if you have tranny fluid in it again. More then likely you need a new radiator
