    22lb/ft is not enough, spec is 30lbs, are the block surfaces true? Exhaust dividers can leak but would think there would some water in other cyl's.

    The early exhaust dividers were a problem for cracking, If the crack is near the bottom it may be spraying water into the #6 ex port only.

    Bad power head gasket letting water through.
