VALVE CLEARANCE ADJUSTMENT 5.0L & 5.7L
Although valve clearance adjustment is not usually required (engine uses hydraulic valve lifters), perform the following procedure after servicing valve train.
Rotate crankshaft until timing marks are aligned and cylinder No. 1 is at TDC of compression stroke (Firing position). Adjust exhaust valves at cylinders 1, 3, 4, and 8, intake valves at cylinders 1, 2, 5, and 7. To adjust, loosen rocker arm adjusting nut until up and down lash is present. Tighten adjusting nut until lash is removed, then tighten adjusting nut one full turn. Rotate crankshaft 360 degrees to bring cylinder No. 6 to TDC of compression stroke and timing marks are aligned. Adjust exhaust valves 2, 5, 6 and 7, intake valves 3, 4, 6 and 8.
