In our setup, the mistral intake does not use hot coolant for intake warming. The two intake coolant ports on the rotor housings were sealed with a plug of silicone and a cursory look indicated those plugs were intact. Also, the ports are essentially blocked by the "blind flange" effect of being covered by the Mistral Intake. On further review I need to mention that examining the thick spacer and its "geared wheel" appearance..from welding to the bearing.. The appearance is uniform all the way around, so maybe it wasnt pinched after all but failed nonetheless. Or maybe I'm just grasping at straws. either way its clear it failed.. and considering installation is a known failure point with this part.. Ok.. off to the Rodeo to work my shift.. Dave
