ABSTRACT:
The detached cylinder head is placed on a table or other flat surface which has a recessed area within which is retained a deformable elastic bladder. Air, water or some other fluid is introduced into the bladder causing it to expand so that it conforms to the chambers within the cylinder head. The pressure of the expanded bladder within the chamber forces the valve upward against the valve seat. Once the valve is pressed upward against the valve seat, the valve can be disassembled by depressing the spring and removing the fastener, so that the spring can be removed, or the spring can be put in place and the valve reconnected.
