2009 Ford Expedition Intake Valve Parts Q&A

• Q: How Do Exhaust Valve and Intake Valve Stem-to-Guide Clearances Affect Service and Repair on 2009 Ford Expedition?

  A: The service process starts with checking the valve stem diameter according to specifications and follows by validating the valve stem-to-valve guide clearance measurement. In case of instability use a magnetic base. You should position the Valve Guide Clearance Gauge onto the valve stem while using a Dial Indicator Gauge with Holding Fixture for attachment. Place the clearance gauge at the upper surface of the valve guide while regulating the valve. Moving the Valve Guide Clearance Gauge toward the Dial Indicator Gauge with Holding Fixture enables you to set the Dial Indicator Gauge to zero. Read and record the measurement from the Dial Indicator Gauge with Holding Fixture as it moves away from the Valve Guide Clearance Gauge because this figure indicates the valve stem-to-valve guide clearance twice over.
