A variable cam timing phaser for an internal combustion engine with at least one camshaft includes a housing (144), a rotor (138), and a phaser control valve (168). The phase control valve is offset from a center axis of rotation through the camshaft of the phaser and may also be parallel to the center axis of rotation. The phaser control valve directs fluid flow to shift the relative angular position of the rotor relative to the housing. The phaser may be cam torque actuated, oil pressure actuated, or torsion assist.
