I can't understand why anyone would want to use Bar's leak.
However, I do believe in Moroso Ceramic Engine Sealer... and this tale
points to the need for bleeding the thermostat housing before adding the
moroso... (and don't bleed it while moroso is the coolant system... cause
wherever there is metal, water, and air moroso will act to seal it up in the
presence of heat... {?}... which includes your bleeders, and any screw
threads... )
