Oil Control Valve Inspection

S6JB0A1416015

Oil Control Valve

1) Inspect strainer (1) and mating surface (2) of oil

control valve for clog or damage. Clean oil control
valve if clog or foreign matter is present on strainer
or mating surface of oil control valve.
Replace oil control valve if its mating surface is
damaged.

2) Check resistance between terminals of oil control

valve.

Oil control valve resistance

Timing Chain and Chain Tensioner Removal
and Installation

S6JB0A1416017

Removal

CAUTION

!

After timing chain is removed, never turn
crankshaft and camshafts independently
more than its allowable turning range
described in “Installation”.
If turned, interference may occur between
piston and valves and valves themselves,
and parts related to piston and valves may be
damaged.

1) Remove timing chain cover referring to “Timing

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

2) By turning crankshaft, align both intake and exhaust

camshaft timing sprocket marks (1) with notches (2)
of cylinder head respectively and align crankshaft
sprocket key (3) with notch of cylinder block (4).

3) Remove timing chain tensioner adjuster assembly

(5).

4) Remove timing chain tensioner (6).
5) Remove timing chain No.1 guide (7).
6) Remove timing chain (8) with crankshaft timing

sprocket (9).

Installation

CAUTION

!

After timing chain is removed, never turn
crankshaft and camshafts independently
more than such an extent (“a”, “b”) as shown
in the figure.
If turned, interference may occur between
piston and valves and valves themselves,
and parts related to piston and valves may be
damaged.

1) Check that match marks (1) on intake and exhaust

camshaft timing sprockets are in match with notches
(2) on cylinder head as shown in the figure.

2) Set key (3) and turn crankshaft to position key on

upside of crankshaft.

3) Install timing chain by aligning dark blue plate (1) of

timing chain and triangle mark (2) on camshaft
timing sprocket as shown in the figure.

4) Fit crankshaft timing sprocket to timing chain by

aligning gold plate (3) of timing chain and circle mark
(4) on crankshaft timing sprocket. Then install
crankshaft timing sprocket fitted with chain to
crankshaft.

5) Apply engine oil to sliding surface of timing chain

No.1 guide (1) and install it as shown in the figure.
Tighten guide bolts to specified torque.
