  2. CHECK VALVE CLEARANCE


    1. A01CJ11E01

      Set the No. 1 cylinder to TDC/compression.

    2. A01CGRRE01

      Check the valve clearance of the No. 1 cylinder intake valve and the No. 3 cylinder exhaust valve.

      Valve clearance (Cold)
      Intake
      0.30 mm (0.0118 in.)
      Exhaust
      0.45 mm (0.0177 in.)

      Note

      Do not apply excessive force to the valve adjusting screw.

      Tech Tips

      If the clearance is not as specified, record the out-of-specification measurement, then adjust the valve clearance.

    3. A01CJ4ZE01

      Check the valve clearance of the No. 1 cylinder exhaust valve and the No. 2 cylinder intake valve.

      Valve clearance (Cold)
      Intake
      0.30 mm (0.0118 in.)
      Exhaust
      0.45 mm (0.0177 in.)

      Note

      Do not apply excessive force to the valve adjusting screw.

      Tech Tips

      If the clearance is not as specified, record the out-of-specification measurement, then adjust the valve clearance.

    4. Turn the crankshaft by a further 360° clockwise.

    5. A01CJ11E01

      Set the No. 4 cylinder to TDC/compression.

    6. A01CGOFE02

      Check the valve clearance of the No. 2 cylinder exhaust valve and the No. 4 cylinder intake valve.

      Valve clearance (Cold)
      Intake
      0.30 mm (0.0118 in.)
      Exhaust
      0.45 mm (0.0177 in.)

      Note

      Do not apply excessive force to the valve adjusting screw.

      Tech Tips

      If the clearance is not as specified, record the out-of-specification measurement, then adjust the valve clearance.

    7. A01CGMTE02

      Check the valve clearance of the No. 3 cylinder intake valve and the No. 4 cylinder exhaust valve.

      Valve clearance (Cold)
      Intake
      0.30 mm (0.0118 in.)
      Exhaust
      0.45 mm (0.0177 in.)

      Note

      Do not apply excessive force to the valve adjusting screw.

      Tech Tips

      If the clearance is not as specified, record the out-of-specification measurement, then adjust the valve clearance.

  3. ADJUST VALVE CLEARANCE

    A01CH8ZE01

    1. Turn the crankshaft clockwise to align the matchmark on the crankshaft pulley with the pointer on the timing gear case.

      Tech Tips

      If not, turn the crankshaft 1 revolution (360°) to align the matchmark.

    2. A01CHWVE01

      With the No. 1 piston positioned at TDC on the compression stroke, using a feeler gauge, adjust each valve clearance.

      Valve clearance (Cold)
      Intake
      0.30 mm (0.0118 in.)
      Exhaust
      0.45 mm (0.0177 in.)

      Tech Tips

      The feeler gauge should move with a very slight pull.

    3. Loosen the lock nut on the valve rocker arm and loosen the adjusting screw.

    4. Insert a 0.30 mm (0.012 in.) feeler gauge for the intake or a 0.45 mm (0.018 in.) feeler gauge for the exhaust between the adjusting screw on the valve rocker arm and the valve bridge.

    5. Turn the adjusting screw on the valve rocker arm until the feeler gauge slides with a very slight drag, and lock the adjusting screw with the lock nut.

  5. BLEED AIR FROM FUEL SYSTEM


    1. A01CGS9

      Loosen the fuel filter's air bleed plug.

    2. A01CGKM

      While covering the drain pipe with a shop rag or a piece of cloth, press and release the priming pump until the fuel from the drain pipe does not have any bubbles.

    3. A01CIWK

      Tighten the air bleed plug.

      Note

      Do not use any tools.

  6. INSPECT FOR FUEL LEAK


    1. Perform the Active Test.


      1. Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.

        Note

        Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.

      2. Connect the intelligent tester to the DLC3.

      3. Start the engine.

      4. Turn the intelligent tester on.

      5. Select the following menu items: Powertrain / Engine / Active Test.

      6. Perform the Active Test.
