Abstract
A pistol grip spring compressor system including a spring lock unit, an actuator assembly, and an anvil module such that the spring lock unit secures a valve spring coil of a valve spring unit from an internal combustion engine in a fixed position relative to a frame element to permit an anvil, provided by the anvil module and positioned against a valve spring retainer of the valve spring unit, to maintain compression on the valve spring while the valve spring unit is separated from an automobile internal engine combustion block.
