10) Apply engine oil to timing chain and then turn 

crankshaft clockwise by 2 revolutions and check that 
match marks (1) on intake and exhaust camshaft 
timing sprockets are in match with notches (2) on 
cylinder head and key (3) is in match with notch (4) 
on cylinder black as shown in the figure.
If each marking chain and each match mark are no 
matches, adjust each sprockets and timing chain.

CAUTION

!

 

• Keep working table, tools and hands clean 

while overhauling.

• Use special care to handle aluminum parts 

so as not to damage them.

• Do not expose removed parts to dust. 

Keep them always clean.

 

Removal

1) Remove timing chain cover referring to “Timing 

Chain Cover Removal and Installation: For M16A 
Engine with VVT”.

2) Remove timing chain referring to “Timing Chain and 

Chain Tensioner Removal and Installation: For M16A 
Engine with VVT”.

3) With hexagonal section (1) of intake camshaft (2) 

held stationary with spanner or the like, loosen 
mounting bolt of intake cam timing sprocket 
assembly (3) and remove it.

CAUTION

!

 

Never attempt to loosen mounting bolt with 
intake cam timing sprocket assembly held 
stationary. Failure to follow this could result 
in damage to lock pin.
Do not loosen bolt “a” because intake cam 
timing sprocket assembly is not serviceable.

4) Loosen camshaft housing bolts in such order as 

indicated in the figure and remove them.

5) Remove camshaft housings.
6) Remove intake and exhaust camshafts.
7) Remove camshaft bearing (1).

8) Remove tappets (2) with shims (1).

Installation

1) Install tappets and shims to cylinder head.

Apply engine oil around tappet and then install it to 
cylinder head.

NOTE
When installing shim, make sure to direct 
shim No. side toward tappet.

 

2) Install camshaft bearing (1) to cylinder head.

CAUTION

!

 

Do not apply engine oil to camshaft bearing 
back.
Only a upper half bearing of intake camshaft 
bearing No.1 has some holes. Other 
bearings.

3) Install intake camshaft (1) and exhaust camshaft (2).

Align knock pin (3) and match mark (4) with notches 
(5) as shown in the figure.

NOTE
Before installing camshafts, turn crankshaft 
until key position faces upward.
Refer to “Timing Chain and Chain Tensioner 
Removal and Installation: For M16A Engine 
with VVT”.

 

4) Apply engine oil to sliding surface of each camshaft 

and camshaft journal then install them as shown in 
the figure.

5) Install camshaft housing pins (1) as shown in the 

figure.

6) Check position of camshaft housings.

Embossed marks are provided on each camshaft 
housing, indicating position and direction for 
installation. Install housings as indicated by these 
marks.

7) After applying engine oil to housing bolts, tighten 

them temporarily first. Then tighten them by the 
numerical order in the figure. Tighten a little at a time 
and evenly among bolts and repeat tightening 
sequence two or three times before they are 
tightened to specified torque.

Tightening torque
Camshaft housing bolt (a):  11 N·m (1.1 kgf-m, 
8.0 lb-ft)

8) With hexagonal section (1) of intake camshaft (2) 

held stationary with spanner or the like, tighten bolt 
of intake cam timing sprocket assembly (3) to 
specification.

Tightening torque
Intake cam timing sprocket bolt (a):  60 N·m (6.0
