Tech Tips


  • Use the same procedure for the Bank 2 side and Bank 1 side.

  • The following procedure is for the Bank 1 side.

PROCEDURE


  1. REMOVE VALVE ADJUSTING SHIM


    1. B000URT

      Remove the 16 valve adjusting shims from the cylinder head LH.

      Tech Tips

      Arrange the removed parts in such a way that they can be installed to their original locations.

  2. REMOVE LH CYLINDER HEAD INTAKE VALVE


    1. B000UWGN02

      Using SST, compress the LH cylinder head intake valve and remove the 16 LH cylinder head valve spring retainer locks.

      SST
      09202-70020   ( 09202-00010, 09202-01010, 09202-01020 )

    2. Remove the 8 LH cylinder head valve spring retainers, 8 LH cylinder head intake valve compression springs and 8 LH cylinder head intake valves from the cylinder head LH.

      Tech Tips

      Arrange the removed parts in such a way that they can be installed to their original locations.

  3. REMOVE LH CYLINDER HEAD EXHAUST VALVE


    1. B000Z33N02

      Using SST, compress the LH cylinder head exhaust valve and remove the 16 LH cylinder head valve spring retainer locks.

      SST
      09202-70020   ( 09202-00010, 09202-01010, 09202-01020 )

    2. Remove the 8 LH cylinder head valve spring retainers, 8 LH cylinder head exhaust valve compression springs and 8 LH cylinder head exhaust valves from the cylinder head LH.

      Tech Tips

      Arrange the removed parts in such a way that they can be installed to their original locations.

  4. REMOVE LH CYLINDER HEAD INTAKE VALVE STEM OIL SEAL


    1. B000TRR

      Using pliers, remove the 8 LH cylinder head intake valve stem oil seals.

  5. REMOVE LH CYLINDER HEAD EXHAUST VALVE STEM OIL SEAL


    1. B000W7K

      Using pliers, remove the 8 LH cylinder head exhaust valve stem oil seals.

  6. REMOVE LH CYLINDER HEAD VALVE SPRING SEAT


    1. B000TXQ

      Using compressed air and a magnet hand, remove the 16 LH cylinder head valve spring seats from the cylinder head LH by blowing air onto them.

      Tech Tips

      Arrange the removed parts in such a way that they can be installed to their original locations.

  7. REMOVE NO. 1 STRAIGHT SCREW PLUG


    1. B000XJV

      Using a 10 mm hexagon socket wrench, remove the 6 No. 1 straight screw plugs and 6 screw plug gaskets.

      Note

      If coolant leaks from a No. 1 straight screw plug or the No. 1 straight screw plug is corroded, replace it.

  8. REMOVE NO. 2 STRAIGHT SCREW PLUG


    1. B000VQP

      Using a 14 mm hexagon socket wrench, remove the 2 No. 2 straight screw plugs and 2 screw plug gaskets.

      Note

      If coolant leaks from a No. 2 straight screw plug or the No. 2 straight screw plug is corroded, replace it.

  9. REMOVE STUD BOLT

    Note

    If a stud bolt is deformed or the threads are damaged, replace it.


    1. Using E6 and E8 "TORX" socket wrenches, remove the stud bolts.
