  1. Remove carbon and varnish deposits from inside of valve guides with a reliable guide cleaner.
  2. Measure valve stem-to-guide clearance as follows:
  3. Install valve (2) into cylinder head so it is 15 mm (0.590 inch.) off the valve seat. A small piece of hose may be used to hold valve in place.
  4. Attach dial indicator Tool C-3339A(1) to cylinder head and set it at right angle of valve stem being measured.
  5. Move valve to and from the indicator. For clearance specifications. See Engine - Specifications .
    NOTE: If stem-to-guide clearance exceeds specifications, you must measure valve stem. If valve stem is within specifications or if guide is loose in cylinder head, replace cylinder head.
