Valve Guide Servicing: Replacement
- Using hammer and drift, tap valve guide firmly enough to break guide off flush with cylinder head surface. Remove snap ring. Gradually heat head to 176-212°F (80-100°C). Using Valve Guide Driver (09201-60011), drive guide out toward block side.
- Measure cylinder head hole for valve guide. On Camry & Celica engines, standard guide hole diameter is .5118-.5129" (13.000-13.027 mm). Maximum rebored cylinder head guide bore diameter is .5138-.5148" (13.050-13.077 mm).
- On Celica GTS engines, standard guide hole diameter is .4331-.4338" (11.0-11.018 mm). Maximum rebored cylinder head guide bore diameter is .4350-.4357" (11.050-11.068 mm). If guide hole measures more than specification, machine guide hole for oversized guide. If guide bore exceeds maximum specification, cylinder head must be replaced.NOTE: On Celica GTS engines, intake valve oil seal is Brown and exhaust valve oil seal is Black.
- Drive in new guide using Valve Guide Remover and Installer (09201-60011) until snap ring comes in contact with cylinder head. See Fig 1. Using an 8 mm reamer for Camry and Celica engines or a 6 mm reamer for Celica GTS engines, finish guide bore to specified clearance. Reface valve seat surface as needed.
