no engine oil pressure to the CMP actuator, the high tension spring positions camshaft timing at CMP System Lubrication Flow and Actuator Operation Fig. 41: Cutaway View Of Actuator 1. Oil enters the camshaft at the second main bearing journal (1). 2. Oil travels through the camshaft into the CMP actuator valve check ball (2) and filter (3). 3. Oil exits the valve and travels through the internal passages of the camshaft (4). 4. Oil exits the camshaft and enters the actuator oil entry ports. 5. Oil travels through the actuator and is directed back into the valve (5). 6. Valve spool position directs oil to the advance or retard passages of the actuator. The valve may also, under certain conditions, be positioned in a neutral position with no flow to

Fig. 42: Identifying Actuator Passages 1. Oil flows from the camshaft into the valve inlet (3) through the internal check ball and filter. 2. Oil exits the valve (2) and travels within the internal passages of the camshaft into the entry ports (7) of the actuator. 3. The center oil groove of the actuator is pressurized and oil reenters the valve (1). 4. Valve spool position directs oil out of the valve advance (5) or retard (4) ports to the actuator. The valve may also, under certain conditions, be positioned in a neutral position with no flow to
