Valve Springs: Removal

  1. Remove rocker arm cover and spark plug on cylinder to be serviced. Install air line with adapter in spark plug hole.
    NOTE: If air pressure fails to hold valve closed, remove cylinder head for inspection of valve seat.
  2. Remove required rocker arms and push rods. On 302" engines, remove exhaust valve stem caps. Use suitable spring compression tool to compress valve and remove retainer locks, sleeve (302" & 351"W only), spring retainer and valve spring. Remove and discard valve stem seal. Do not remove air pressure as this will allow valve to fall into cylinder if piston is at bottom of cylinder.
