Cylinder Head: Installation

  1. To install, reverse removal procedure. Before installing cylinder head bolts, apply light coat of engine oil to threads and below bolt heads.
  2. Tighten cylinder head bolts in sequence. See Figure . Tighten bolts in several steps to specification. See TORQUE SPECIFICATIONS table at end of article.
  3. If cylinder head components were serviced, check valve clearance. See VALVE CLEARANCE ADJUSTMENT under ADJUSTMENTS.
  4. Ensure reference mark is aligned on distributor. If fuel injectors were removed from fuel rail, install new grommet and "O" ring on each fuel injector and insulators in cylinder head. Lubricate "O" ring with gasoline before installing fuel injector on fuel rail.
