Valve Guide Installation

  1. Chill new valve guides in freezer for about one hour. Remove new valve guides from freezer as needed. Slip a .234" (6 mm) steel washer over Valve Guide Driver (07742-6570100).
  2. Install new valve guides from camshaft side of cylinder head. Drive each guide into heated head until washer bottoms against head. If replacing all valve guides, reheat cylinder head as necessary.
  3. Intake valve guide installed height must be .974-.994" (24.75-25.25 mm). Exhaust valve guide installed height must be .632-.652" (16.05-16.55 mm). Using cutting oil, ream new valve guides by rotating Valve Guide Reamer (07HAH-PJ7010A or 07HAH-PJ7010B) clockwise the full length of valve guide bore. Measure valve stem oil clearance. See CYLINDER HEAD  table under ENGINE SPECIFICATIONS.
NOTE: Always reface valve seat after replacing valve guide.
