Valve Guide Inner Diameter
WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- Measure each valve guide by using a small hole gauge and a 0-25 mm (0-1 in) outside micrometer. Record each valve guide inner diameter so valve-to-guide running clearance may be determined. If valve guide inner diameter exceeds specifications, install a new cylinder head.
- Using the valve guide inside diameter and the valve stem diameter measurements, determine valve stem-to-guide running clearance, install new valves as required. For additional information, refer to SPECIFICATIONS .
