If you are connected in the housing below the T-stat and at the block drain isn't the pressure the same at both ends? why would the water flow?
Possibly because the front connection is closer to the pump?
This is exactly what I was thinking. I guess even if you have equal pressures at each end, you still have a heated manifold. Your just doing it by having stagnant water inside the manifold.
It would be nice if Tlowe could do a test for us by making a copy of a clear Clifford manifold and running a motor on the dyno with clear hoses so we could see what is actually going on. LOL!
