    Strangely the drill test (see pic)  directly on the drive shaft  at the  top of the lower section shows tons of water shooting out and should flood the  engine’s water cavities… cyl jackets and all.  A section of  SS  steel cable (small & flexible ) on a drill should work it’s way around the engine’s  water cavity  and  hopefully exit somewhere clearing out any debris.

    the amount of water gushing out on the drill tests should eliminate any  possibility of obstructions below the impeller  housing.  should….

    hopefully  the  PH is the original CD12 PH and  matches the base gasket pattern ….OMG !

     

     

    up the creek nothing works…?  pulling welsh /frost plugs  may provide ” insight” to cavity blockages..
