Valve Guide Inner Diameter

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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.
