Valve Guide: Service and Repair
DESCRIPTION
If the valve stem-to-valve guide clearance exceeds the service clearance, replace the valve guide and ream the valve guide to the standard diameter
of 7.02-7.04 mm (0.276-0.277 inch). Always reface the valve seat after the valve guide has been replaced.
REPLACEMENT
1. Press out original guide and install service bushing.
2. Hand ream the valve guide.
3. Use a suitable scraper to break the sharp corner (ID) at the top of the valve guide. Failure to do so may result in possible valve train wear and/or
damage.
4. Reface valve seat as required. Install standard-size valve stem seal.
5. Check valve lash (collapsed tappet gap).
