For my clarification… When I have a Stat in. water should be pumping out the back whether or not the Stat is opened or closed.. Correct?? When I had the stat in, water was not peeing out, Took out the stat, water was peeing..
That’s right. Water should be coming out of the exhaust relief at all times.
With this motors symptoms, I’d first remove the cover and check the small passage between the cover and the gasket for blockage.
