Valve Guides

WARNING: This page is about a different car, the 2001 Ford Pickup, 2001 Ford Econoline, 2000 Ford Pickup, and 2000 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
  1. Valve guides must be reamed for an oversize valve if valve stem oil clearance exceeds specification. See CYLINDER HEAD  table under ENGINE SPECIFICATIONS. Valves are available in .015" (.38 mm) and .030" (.76 mm) oversize.
  2. If oversize valves or oversize valve stem oil seals are not available, valve guide may be replaced with NEW guide. Always use reamers in proper sequence (smallest first).
NOTE: Always grind valve seat after valve guide has been reamed or new guide has been installed.
