Installation
Continuous Variable Valve Timing (CVVT)
1.

Install the continuous variable valve timing (CVVT) assembly.

Tightening torque :

64.7 ~ 76.5 N.m (6.6 ~ 7.8 kgf.m, 47.7 ~ 56.4 lb-ft)

caution
●

Install camshaft-inlet to dowel pin of CVVT assembly.

At this time, attend not to be installed to oil hole of camshaft-inlet.

●

Hold the hexagonal head wrench portion of the camshaft with a vise, and install the bolt and CVVT assembly.

●

Do not rotate CVVT assembly when camshaft is installed to dowel pin of CVVT assembly.

A.

A: LH exhaust CVVT

B.

B: LH intake CVVT

C.

C: RH intake CVVT

D.

D: RH exhaust CVVT

note

When installing the CVVT assembly bolt, prevent the camshaft from rotating by using a wrench at position (A).

2.

Install the timing chain.

LH Intake and Exhaust camshaft
caution
●

Be careful the right, left bank, intake, exhaust side before assembling.

●

Assemble the key groove of camshaft rear side to the same level of head top surface.

●

Apply a light coat of engine oil on camshaft journals.

1.

Install the LH camshaft assembly (A).

2.

Install the LH camshaft bearing cap (A) and thrust bearing cap (B).

Tightening torque

1st step : 5.8 N.m (0.6 kgf.m, 4.3 lb-ft)

2nd step :

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

caution

Be sure to install the thrust bearing cap bolts and the bearing cap bolts in the correct place.

note

Be careful the right, left bank, intake, exhaust side before assembling.

A : L(LH),R(RH)

B : I(Intake), E(Exhaust)

C : Journal number

D : Front mark

caution

Rotate the crankshaft not to contact the valves to the pistons by making the pistons below 10mm(0.3937in.) from the top of cylinder block.

3.

Install the RH exhaust camshaft oil control valve (OCV) (A).

(Refer to Engine Control/Fuel System - "Oil Control Valve")

Tightening torque :

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

4.

Install the timing chain.
