Valve Guide Removal

WARNING: This page is about a different variant/trim than selected.
  1. Use a hot plate or oven to heat cylinder head to 300°F (150°C). Use Valve Guide Driver (07942-6570100), or fabricate valve guide remover from an air impact chisel. See Fig 1 . Using an air hammer and valve guide remover, drive valve guide 5/64" (2 mm) toward combustion chamber.
    CAUTION: DO NOT heat cylinder head with a torch, or heat cylinder head hotter than 300°F (150°C). Excessive heat may loosen valve seats.
  2. Turn head over. Working from combustion chamber side of head, drive valve guide out toward camshaft side of head. If valve guide does not move, drill valve guide using a 5/16" bit, then try to drive it out again.
CAUTION: Drill guides in extreme cases only. Cylinder head damage can occur if valve guide breaks.
