  4. Apply liquid gasket to the mating surface of cam carrier RH as shown in the figure.
    NOTE:
    • Before applying liquid gasket, degrease the old liquid gasket seal surface of the cylinder head RH and cam carrier RH.
    • Install within 5 min. after applying liquid gasket.

      Liquid gasket: 

      THREE BOND 1217G (Part No. K0877Y0100), THREE BOND 1217H or equivalent

      Liquid gasket applying diameter: 

      3±0.5 mm (0.1181±0.0197 in) range A

  6. Set the part so that the intake manifold is on the upper side.
  7. When the cam carrier RH has been disassembled
    NOTE: When the cam carrier RH has been disassembled, perform the following steps also.
    1. Install the cam sprocket RH. Ref. to MECHANICAL (H4DOTC)>Cam Sprocket>INSTALLATION>CAM SPROCKET RH .
    2. Install the scavenge pump. Ref. to LUBRICATION(H4DO)>Scavenge Pump>INSTALLATION .
    NOTE: When installing the scavenge pump, do not turn the intake camshaft RH to the outside of range of zero-lift (in range where it can be turned lightly by hand).
  8. Check the cam clearance. Ref. to MECHANICAL (H4DOTC)>Cam Clearance>INSPECTION>WHEN TIMING CHAIN ASSEMBLY IS REMOVED .
  9. Connect the water pipe hose to oil pan upper and EGR cooler, and install the water pipe assembly.

    Tightening torque: 

    6.4 N.m (0.7 kgf-m, 4.7 ft-lb)
