Quote: Ran a solid no whole motorplate for years with a Meziere pump. All you are doing is sealing the water off. That empty cavity in the timing chain cover just fills up with water that basically never moves.
Me too, not sure how that is any diferent than what the Meziere plate does?
The Meziere plate is machined on the back side to block off the cavity area. It wouldn't matter if everything was perfectly balanced in the cooling system, but if one side of the engine has some extra flow resistance, all the water will go to the other side.
