Also...it seems that some of that leak at bottom hose was spraying UP onto the Tstat housing...making me think it was housing or seal. Im pretty sure I solved this one. Hope this helps someone out there. Check for corrosion on water pump where lower Rad hose attaches to the pump. If you see aluminum corrosion, removing it with emory cloth is not enough. You must apply some sort of sealing aluminum primer or maybe Permatex Hytack. Im confident with Zinc Phosphate Primer.

Glad to see you got it sealed up hopefully for good.Good tip on the Zinc Phosphate Primer for sealing aluminium and slowing it's corrosion factor.
