5.0L Valve Clearance Adjustment

NOTE: Hydraulic valve lifters are used; no valve adjustment is required. If valve clearance is incorrect, use oversize or undersize push rods to correct clearance.
  1. Rotate crankshaft in normal operation direction until No. 1 cylinder is at TDC of compression stroke. Using Lifter Bleed Down Wrench (T71P-6513-B), apply pressure to No. 1 intake valve lifter tappet until lifter is completely bottomed.
  2. Hold valve lifter in this position while measuring clearance between valve lifter and valve stem. Record measurement. Repeat this procedure for intake valves No. 7 and 8, and exhaust valves No. 1, 4 and 5.
  3. Rotate crankshaft 180 degrees (1/2 turn). Bleed lifter and check intake valves No. 4 and 5, and exhaust valves No. 2 and 6. Rotate crankshaft 270 degrees (3/4 turn). Bleed lifter and check intake valves No. 2, 3 and 6, and exhaust valves No. 3, 7 and 8. See 5.0L COLLAPSED VALVE LIFTER CLEARANCE table. If clearance is not within specification, use shorter or longer push rod to obtain correct clearance.
