>>A<< Valve Stem Seal Installation

CAUTION:
  • The valve stem seal must not be reused.
  • Do not damage the tappet wall during assembly.
  • Be sure to use a special tool to install the valve stem seal. Poor installation causes oil loss via valve guides.
  • If oil is not applied, the valve stem seal may rise to the surface after it is press fitted.
  1. Apply a thin coat of engine oil to a new valve stem seal.
