INSTALLATION

1. Install the O-rings to cylinder head RH, cylinder head LH, cylinder block LH and oil pan upper.

NOTE:

• Use new O-rings.

• Apply a coat of engine oil to the O-rings.

2. Apply liquid gasket if there are gaps between front camshaft cap and cam carrier (A), cam carrier and cylinder head (B), and cylinder head and cylinder block (C) as shown in the figure.

Liquid gasket:

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

3. Apply liquid gasket to the chain cover mating surface and center boss (5 places) as shown in the figure.

NOTE:

• Before applying liquid gasket, degrease the old liquid gasket seal surface of the engine and chain cover.

• Install within 5 min. after applying liquid gasket.

Liquid gasket:

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

• Use a new O-ring to the oil level gauge guide.

• Apply a light coat of engine oil to the O-rings of the oil level gauge guide and the oil level gauge.

Tightening torque:

T1: 6.4 N·m (0.7 kgf-m, 4.7 ft-lb)

T2: 36 N·m (3.7 kgf-m, 26.6 ft-lb)

6. Connect the terminal (A) to the oil pressure switch, connector (B) to the engine oil temperature sensor, connector (C) to the intake oil control solenoid LH, connector (D) to the exhaust oil control solenoid LH, connector (E) to the intake camshaft position sensor LH, and connector (F) to the exhaust camshaft position sensor LH, and secure the engine harness with the clips (G) and (H).

NOTE:

The oil pressure switch harness must be positioned toward the left lower side of the vehicle within the range of 90°.

(a)

Left side of vehicle

Tightening torque:

1.5 N·m (0.2 kgf-m, 1.1 ft-lb)

7. Attach the rubber cap to the oil pressure switch.

8. Secure the oil level switch harness with clips (A), and connect the connectors to the oil level switch.

9. Connect the connector (A) to the intake oil control solenoid RH, connector (B) to the exhaust oil control solenoid RH, and connector (C) to the intake camshaft position sensor RH, and then secure the engine harness with the clips (D) and (E).

10. Connect the connector (A) to the exhaust camshaft position sensor RH, and install the engine harness stay to the chain cover.

Tightening torque:

6.4 N·m (0.7 kgf-m, 4.7 ft-lb)
