>>D<< THRUST CAMSHAFT BEARING 
CAP/CAMSHAFT BEARING CAP/OIL FEEDING 
CAMSHAFT BEARING CAP INSTALLATION

1. Install the camshaft bearing caps to the cylinder heads.

NOTE: Because the thrust camshaft bearing cap and cam-
shaft bearing cap are the same in shape, check the bearing 
cap number and additionally its symbol to identify the intake 
and exhaust sides for correct installation.

2. Tighten each camshaft bearing cap mounting bolt to the 

specified torque in the order of number shown in the figure 
in two or three steps.

Tightening torque: 12 

± 1 N⋅ m (107 ± 8 in-lb)

.

>>E<< FRONT CAMSHAFT BEARING CAP 
ASSEMBLY INSTALLATION

CAUTION

When the mounting bolts are tightened with the front cam-
shaft bearing cap tilted, the front camshaft bearing cap is 
damaged. Install the front camshaft bearing cap properly 
to the cylinder head and camshaft.
1. Install the front camshaft bearing cap to the cylinder head, 

and temporarily tighten the front camshaft bearing cap to the 
specified torque in the order of the figure (1).

Tightening torque: 17 

± 3 N⋅ m (13 ± 2 ft-lb)

2. Tighten the front camshaft bearing cap again to the specified 

torque in the order of the figure (2).

Tightening torque: 30 

± 2 N⋅ m (23 ± 1 ft-lb)

>>F<< FUEL HIGH-PRESSURE HOSE 
CONNECTION

CAUTION

• When pushing in the retainer of the fuel high-pressure 

hose connector, pay attention to avoid damage to the 
retainer.

• After the installation of the fuel high-pressure hose, 

slightly pull the fuel high-pressure hose to check that it 
is connected securely. At this time, also check that 
there is approximately 1 mm (0.04inch) play.

1. Securely insert the fuel rail stopper into the fuel 

high-pressure hose connector groove to install the fuel 
high-pressure hose to the fuel rail.

2. Push in the retainer of the fuel high-pressure hose 

connector to lock the fuel high-pressure hose and fuel rail.
