ABSTRACT:
Apparatus for testing engine heads of internal combustion engines of various sizes for fluid tightness of internal cavities in a head which commmunicate with ports in the fire deck surface of the head. A universal mounting frame for a cylinder head is rotatable on a longitudinal pivot axis to position the head with its fire deck surface at any orientation relative to the axis. Longitudinal support rails are positioned above the water ports, and spring loaded stopper means and fluid supply and venting members which are longitudinally adjustable on the rails are aligned with the ports, and the support rails are then moved down to seal the stoppers and heads against the rims of the ports. Compressed air, and then hot water are introduced to the head cavities to check it for leaks.
