Valve Guides

WARNING: This page is about a different car, the 1995 Ford Ranger and 1995 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Valve guides must be reamed for an oversized valve if valve stem oil clearance exceeds specification. See CYLINDER HEAD  table under ENGINE SPECIFICATIONS. Valves are available in .008" (.20 mm) and .016" (.41 mm) oversize.
  2. If oversized valves or oversized valve stem seals are not available, valve guide may be bored out to use a service bushing. Always use reamers in proper sequence (smallest first).
CAUTION: Always grind valve seat after valve guide has been reamed or service bushing has been installed.
