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 the Top Dead Center (TDC) at the end of compression stroke (Position No.1 in the illustration), check the following valves:





2. When compressing valve spring to remove push rods, make sure piston in individual cylinder is below TDC to avoid contact between valve and piston. To replace a push rod, it will be necessary to loosen the rocker arm seat retaining bolt and rotate rocker arm to the side. After replacement of a push rod, rocker arm or hydraulic valve tappet, the engine should not be cranked or rotated until valve tappets have an opportunity to leak down to their normal operating position. The leak-down rate can be accelerated by using a valve tappet bleed-down wrench on rocker arm and applying pressure in a direction to collapse valve tappet.
