Valve Clearance: Adjustments

NOTE: Ford does not provide a TDC (Top Dead Center) mark or determination procedure for this engine in this vehicle.
ALLDATA users have reported success using aftermarket tools to determine TDC on this engine.

1. With No. 1 piston on top dead center (TDC) at the end of compression stroke, check the following valves:
Exhaust valves, No. 1, 3, 6.
Intake valves, No. 1, 2, 4.

2. Rotate crankshaft 360° to position No. 2 and check the following valves:
Exhaust valves, No. 2, 4, 5.
Intake valves, No. 3, 5, 6.

3. Valve clearance (Collapsed Tappet) should be: 2.15-4.69 mm (0.085-0.185 inch).
4. If clearance is excessive, inspect valve train for worn components.
5. If clearance is too low, and valves or valve seats were refaced, the valve stem end may need to be refinished.
